Abstract: In modern clinical practice, Digital Subtraction Angiography (DSA) is a powerful technique for the visualization of blood vessels in a sequence of X-ray images. A serious problem encountered in this technique is the presence of artifacts due to patient motion. The resulting artifacts frequently lead to misdiagnosis or rejection of a DSA image sequence. In this paper, a new technique for removing both global and local motion artifacts is presented. It is based on a 3D space-time motion evaluation for separating pixels changing values because of motion from those changing values because of contrast flow. This technique is proved to be very efficient to correct for patient motion artifacts and is computationally cheap. Experimental results with several clinical data sets show that this technique is very fast and results in higher quality images. (C) 2001 Elsevier Science Ltd. All rights reserved.

Abstract: With the increasing number and complexity of therapeutic coronary interventions, there is an increasing need for accurate quantitative measurements. These interventions and measurements may be facilitated by accurate and reproducible magnifications and orientations of the vessel structures, specifically by accurate 3D vascular tree centerlines. A number of methods have been proposed to calculate 3D vascular tree centerlines from biplane images. In general, the calculated magnifications and orientations are accurate to within approximately 1-3% and 2-5 degrees, respectively. Here, we present a complete system for determination of the 3D vessel centerlines from biplane angiograms without the use of a calibration object. Subsequent to indication of the vessel centerlines, the imaging geometry and 3D centerlines are calculated automatically and within approximately 2 min. The system was evaluated in terms of the intra- and inter-user variations of the various calculated quantities. The reproducibilities obtained with this system are comparable to or better than the accuracies and reproducibilities quoted for other proposed methods. Based on these results and those reported in earlier studies, we believe that this system will provide accurate and reproducible vascular tree centerlines from biplane images while the patient is still on the table, and thereby will facilitate interventions and associated quantitative analyses of the vasculature.

Abstract: Purpose. To compare helical CT-angiography (CTA) and two techniques of MR angiography (MRA) to conventional angiography in aorto-iliac occlusive disease.

Materials and Methods. The abdominal aorta and iliac arteries in 22 patients (4 for preoperative assessment of abdominal aortic aneurysm and 18 for peripheral vascular disease) were imaged using four techniques: digital subtraction angiography ("gold standard"), 2D TOF MR angiography, 3D Gd-enhanced MR angiography and helical CT angiography. Source (CTA and 2D TOF MRA) and MIPed images (after subtraction measures before and after gadolinium injection for 3D Gd-MRA) were reviewed.

Results. Sensitivity, specificity and accuracy for the detection of significant (>50%) stenosis and occlusion of aorto-iliac arteries were respectively: 38%, 89%, 77% for 2D TOF MRA; 75%, 71%, 72% for 3D Gd-MRA and 95%, 90%, 92% for CTA. Excluding the internal iliac arteries, results were 54%, 96%, 88% for 2D TOF MRA; 96%, 80%, 83% for 3D Gd-MRA and 92%, 93%, 95% for CTA.

Conclusion. 3D Gd-MRA, a technique with potential for further improvement, is superior to 2D TOF MRA for detecting significant stenosis and occlusion of aorto-iliac arteries. Results at Gd-MRA are nearly similar to those at CTA (after excluding internal iliac arteries). Results at Gd-MRA are not affected by calcified plaque.

Abstract: The 3 D Heart View project produced an advanced software application fur lime-variant 3D cardiac modelling based on back projection of rotational X-ray angiographic sequences. Due to standard DICOM 3.0 interface, the software can be used as an add-on to any modern digital angiographer. The system accuracy has been measured and the approach has been validated with static and dynamic phantom object studies. The prototype: has been tested in a clinical routine environment us well. In this paper we present the main features of the system, the methodology of 3D angiographic modelling, and certain testing and operation results. We also describe the application of high-performance computing technology in the modelling process. (C) 2000 Elsevier Science Ltd. All rights reserved.

Title: Effect of sex, hemodynamics, body size, and other clinical variables on the corrected Thrombolysis In Myocardial Infarction frame count used as an assessment of coronary blood flow

Abstract: Background Compared with the conventional Thrombolysis in Myocardial Infarction (TIMI) flow grade system, the corrected TIMI frame count (CTFC) quantifies coronary blood flow in a more reproducible Fashion. The purpose of this study was to determine if the CTFC is affected by sex, body size, hemodynamics, or other selected clinical variables.

Methods and Results CTFC was measured in 534 coronary arteries from 200 consecutive patients referred for coronary angiography. CTFC in each artery was related to patient variables (sex, age, race, and body surface area), clinical variables (cardiac rhythm, medication use, diabetes, hypertension, hypercholesterolemia, smoking, and left ventricular hypertrophy), angiographic variables (wall motion abnormality in each coronary artery distribution, left ventricular ejection fraction, percent stenosis in the artery, and presence of collaterals), and hemodynamic variables (aortic systolic and diastolic blood pressure and left ventricular end-diastolic pressure). By multivariate analysis, CTFC in all arteries was significantly associated with aortic systolic and diastolic pressures and body surface area. In addition, there were significant associations between CTFC and age and sex in some but not all arteries. Although significant the absolute change in CTFC associated with these variables was small.

Conclusions CTFC provides a quantitative assessment of coronary blood flow that varies only a small amount in association with body size, systemic arterial pressure, age, and sex.

Abstract: The interpretation of three-dimensional (3D) structures of the coronary tree and the myocardium by a clinician demands a subjective visual integration of two-dimensional (2D) images of cardiac diagnostic procedures like coronary angiography and myocardial scintigraphy. Although in the conventional analysis of 2D display scintigraphic myocardial perfusion segments an arbitrarily assigned to three major coronary artery systems, the standard myocardial perfusion distribution territories correspond with the individual pathologic-anatomic coronary tree in only 50-60% of the patients. Hence, the mental integration of both 2D images of corollary angiography and myocardial scintigraphy does not necessarily allow art accurate assign ment of particular myocardial perfusion regions to the corresponding vessels. For an objective assignment of each vessel segment of the coronary tree to the corresponding myocardial regions, we have developed a 3D " fusion image" technique and applied it to patients with coronary artery disease. Cause-and-effect relationships may be more obvious with 3D data Fusion and may enable an easier comparison of anatomy and physiology.

Preliminary results demonstrate that our newly developed 3D fusion image is useful for accurate assignment of coronary vessel segments to the corresponding myocardial perfusion regions and suggest that it may allow the clinician a comprehensive and accurate assessment of the patient's myocardial status.

Abstract: A method for extraction and labeling of the coronary arterial tree (CAT) using minimal user supervision in single-view angiograms is proposed. The CAT structural description (skeleton and borders) is produced, along with quantitative information for the artery dimensions and assignment of coded labels, based on a given coronary artery model represented by a graph. The stages of the method are: 1) CAT tracking and detection; 2) artery skeleton and border estimation; 3) feature graph creation; and iv) artery labeling by graph matching. The approximate CAT centerline and borders are extracted by recursive tracking based on circular template analysis. The accurate skeleton and borders of each CAT segment are computed, based on morphological homotopy modification and watershed transform. The approximate centerline and borders are used for constructing the artery segment enclosing area (ASEA), where the defined skeleton and border curves are considered as markers. Using the marked ASEA, an artery gradient image is constructed where all the ASEA pixels (except the skeleton ones) are assigned the gradient magnitude of the original image. The artery gradient image markers are imposed as its unique regional minima by the homotopy modification method, the watershed transform is used for extracting the artery segment borders, and the feature graph is updated. Finally, given the created feature graph and the known model graph, a graph matching algorithm assigns the appropriate labels to the extracted CAT using weighted maximal cliques on the association graph corresponding to the two given graphs. Experimental results using clinical digitized coronary angiograms are presented.

Title: Fusion imaging: Combined visualization of 3D reconstructed coronary artery tree and 3D myocardial scintigraphic image in coronary artery disease

Abstract: Background: In patients with coronary artery disease, coronary angiography is performed for assessment of epicardial coronary artery stenoses. In addition, myocardial scintigraphy is commonly used to evaluate regional myocardial perfusion. These two-dimensional (2D) imaging modalities are typically reviewed through a subjective, visual observation by a physician. Even though on the analysis of 2D display scintigraphic myocardial perfusion segments are arbitrarily assigned to three major coronary artery systems, the standard myocardial distribution territories of the coronary tree correspond only in 50-60% of patients. On the other hand, the mental integration of both 2D images of coronary angiography and myocardial scintigraphy does not allow an accurate assignment of particular myocardial perfusion regions to the corresponding vessels. To achieve an objective assignment of each vessel segment of the coronary artery tree to the corresponding myocardial regions, we have developed a 3D 'fusion image' technique and applied it to patients with coronary artery disease. The morphological data (coronary angiography) and perfusion data (myocardial scintigraphy) are displayed in a 3D format, and these two 3D data sets are merged into one 3D image. Results: Seventy-eight patients with coronary artery disease were studied with this new 3D fusion technique. Of 162 significant coronary lesions, 120 (74%) showed good coincidence with regional myocardial perfusion abnormality on 3D fusion image. No regional myocardial perfusion abnormality was found in 44 (26%) lesions. Furthermore, the 3D fusion image revealed 24 ischemic myocardial regions that could not be related to angiographically significant coronary artery lesions. Conclusion: The results of this study demonstrate that our newly developed 3D fusion technique is useful for an accurate assignment of coronary vessel segments to the corresponding myocardial perfusion regions, and suggest that it may be helpful to improve the interpretative and decision-making process in the treatment of patients with coronary artery disease.

Abstract: OBJECTIVE. The purpose of our study was to investigate the value of respiratory-gated three-dimensional (3D) MR angiography in identifying coronary arteries in healthy volunteers and in patients with proximal coronary artery stenosis and to compare the results with those of conventional coronary angiography.

SUBJECTS AND METHODS. Twenty healthy volunteers and 20 patients with coronary artery stenosis were examined on a 1.5-T scanner with a retrospectively respiratory-gated 3D gradient-echo sequence. Visualization of the main coronary arteries was analyzed after curved multiplanar reconstructions. A six-point grading system was used to evaluate 400 vessel segments. The assessment of stenosis was performed by two observers who were unaware of the results of conventional coronary angiography.

RESULTS. The proximal, middle, and distal segments of the coronary arteries were completely identified with or without luminal irregularities in 55%, 47%, and 20%, respectively, of the healthy volunteers. For the 20 patients, results were 69%, 44%, and 20%, respectively. For the assessment of coronary artery stenoses (n = 53), sensitivity was 73% and specificity was 50% after evaluation of the MR angiograms of all patients. A sensitivity of 79% and a specificity of 54% were found for evaluation of the MR coronary angiograms, with an image quality score of at least 3 (i.e., artery segments completely identified with major luminal irregularities).

CONCLUSION. With the navigator echo MR imaging technique, a complete 3D visualization of the main coronary arteries was possible in cases with high image quality. However, further experience with and improvement of the navigator echo technique we used is necessary for reliable assessment of coronary artery stenosis.

Title: Dynamic feature extraction of coronary artery motion using DSA image sequences

Abstract: This paper aims to define and describe features of the motion of coronary arteries in two and three dimensions, presented as geometrical parameters that identify motion patterns. The main left coronary artery centerlines, obtained from digital subtraction angiography (DSA) image sequences, are first reconstructed. Thereafter, global and local motion features are evaluated along the sequence. The global attributes are centerline and point trajectory lengths, displacement amplitude, and virtual reference point, while local attributes are displacement direction, perpendicular/radial components, rotation direction, and curvature and torsion. These kinetic features allow us to obtain a detailed quantitative description of the displacements of arteries' centerlines, as well as associated epicardium deformations. Our modeling of local attributes as quasi-homogeneous on a segment analysis, enables us to propose a novel numeric to symbolic image transformation, which provides the required facts for knowledge-based motion interpretation. Experimental results using real data are consistent with cardiac dynamic behavior.

Abstract: Background: The calculation of absolute artery dimensions in quantitative coronary angiography is usually carried out by catheter calibration. It is based on the proportional comparison of the dimension of the imaged artery segment to the dimension of the imaged angiographic catheter of known size. This calibration method presumes an identical radiographic magnification between angiographic catheter and artery segment of interest. However, due to the different intrathoracic location of both objects the radiographic magnification or calibration factor is often not identical for a given angiographic projection. The aim of this study was to quantify the magnification error (out-of-plane magnification error) for the major coronary artery segments imaged in frequently used angiographic projections. Methods: The intrathoracic spatial location of 468 coronary segments (RCA 196, LAD 156, LCX 116) and their respective coronary catheters were established with biplane angiography and known imaging geometry data. The error in the radiographic magnification or calibration factor was then calculated for ail 936 monoplane projections using the spatial coordinates and imaging geometry data. Results: The mean magnitude of magnification error was 4% within all 936 measurements. The magnitude and direction of error varied with the lesion localization and the angiographic projection angle (range -12.6% to +10.6%). The error characteristics could be described with six typical error groups by stratifying the data according to the three main coronaries and two angiographic planes. In 24% of measurements, the magnification error exceeded the 5.2% error limit acceptable for reference vessel sizing. Measurements of left coronary arteries were mainly affected by it. Conclusion: The magnification error contributes to the calibration error in measuring arterial dimensions by quantitative angiography. This error may affect the reliability of clinical studies and the proper sizing of interventional devices. These findings could be used to improve current error correction algorithms in order to reduce the effect of the magnification error in measuring arterial dimensions.

Abstract: Background The functional significance of the anterograde and retrograde filling of coronaries on angiography is controversial.

Methods and Results Eighteen patients with 27 severe lesions (>85% diameter stenosis) after previous extensive myocardial infarction were selected. The left ventricle was divided into 33 segments for regional comparison of epicardial flow las assessed by angiography) and tissue perfusion as well as metabolism las measured by (NH3)-N-13- and (18)FDG-PET). Viability was defined as normal per fusion (>80% relative of maximum (NH3)-N-13 activity) or mismatch defect (>1.2 metabolism/flow ratio). A method has been developed to register the 'lesion predicted region' determined on the basis of angiography, in the same polar map as derived from the positron emission tomography data. Distal to the lesion, the anterograde epicardial flow was evaluated by Thrombolysis in Myocardial Infarction (TIMI) criteria (TIMI flow 0-3), and retrograde filling was graded on a 0-3 scale (collateral grade 0-3). TIMI flow grade and retrograde collateral grade in every lesion predicted region segment were summed to indicate the total segmental epicardial flow. Out of the 594 segments, 369 were associated with a severe lesion. Among them, significantly higher average perfusion and metabolic activities were found in segments of good epicardial filling (summed epicardial flow greater than or equal to 3) than in the territories of:limited epicardial flow (summed score <3): 65.4 +/- 17% vs 45.6 +/- 10 (P=0.001%) and 68.6+/-16% vs 47.4+/-11% (P=0.0004), respectively. However, when we analysed the predictive value of angiographically detectable good epicardial flow for positron emission tomography viability criteria then the positive predictive value was found to be as low as 0.5; while the negative predictive value was considerably higher (0.82).

Conclusion After myocardial infarction, angiographically detectable limited epicardial flow reveals scarred segments while good epicardial contrast filling does not necessarily indicate maintenance of nutritive function.

Title: Three-dimensional reconstruction of the coronary arteries using a priori knowledge
Source: MEDICAL & BIOLOGICAL ENGINEERING & COMPUTING 1998, Vol 36, Iss 2, pp 158-164

Abstract: A method for 3D reconstruction of the coronary arteries from two radiographic images is presented. A novel technique for matching image structures is the main contribution of the work. After a comprehensive study of the knowledge required to approach this problem, an automatic method, which includes both numeric and symbolic procedures to solve geometric ambiguities, is developed. In the proposed method, all possible (virtual) reconstructions are first obtained. Their validity is evaluated by means of a priori knowledge about the 3D object and its projections, From the set of chosen possible solutions, the most likely solution is selected. The method is tested using real images and is implemented in a platform that allows further clinical validation.
