چکیده
To my Parents, Brother and Sister iii ACKNOWLEDGEMENTS I sincerely thank my advisor Dr. Allen Tannenbaum for giving me support and guidance to carry on my research for the past two years. I take this opportunity to extend my gratitude to Dr. Anthony Yezzi and Dr. Oskar Skrinjar for teaching me various image processing techniques and for being the members of this thesis committee. I would also like to thank Drs. Arthur Stillman and Paolo Raggi of the Emory Medical School for their help in working with and understanding CTA imagery.

Analysis of Soft Plaque Detection Methods in Cta Images
Cardiovascular diseases are considered primary cause for increasing rate of mortality. Automatic stenosis detection in CTA data is highly demanded by clinicians to analyze the coronary related abnormalities timely. The detection of vulnerable plaques in CTA is challenging because these plaques may exhibit similar appearance to nearby blood and muscle tissues. Moreover, accuracy of stenosis dete...
متن کاملDetection of Symptomatic Carotid Plaque Using Source Data from MR and CT Angiography: A Correlative Study.
BACKGROUND Carotid plaque MRI has been a useful method to characterize vulnerable atherosclerotic plaque elements. Recent investigations have suggested that source images from CT angiography (CTA) and MR angiography (MRA) can identify the simple high-risk features of symptom-producing carotid artery plaque. We studied the correlation and relative diagnostic accuracies of CTA and MRA source imag...
متن کاملSoft Plaque Detection and Automatic Vessel Segmentation
The ability to detect and measure non-calcified plaques (also known as soft plaques) may improve physicians’ ability to predict cardiac events. This is a particularly challenging problem in computed tomography angiography (CTA) imagery because plaques may have similar appearance to nearby blood and muscle tissue. This paper presents an effective technique for automatically detecting soft plaque...
متن کاملAssociation between Carotid Plaque Features on CTA and Cerebrovascular Ischemia: A Systematic Review and Meta-Analysis.
BACKGROUND CTA is a widely available imaging examination that may allow the evaluation of high-risk carotid plaque features. PURPOSE Our aim was to evaluate the association between specific carotid plaque features on CTA and ipsilateral cerebrovascular ischemia. DATA SOURCES We performed a systematic review of Ovid MEDLINE, Ovid Embase, Scopus, and the Cochrane Library from inception to Mar...
متن کاملPrediction of Carotid Intraplaque Hemorrhage Using Adventitial Calcification and Plaque Thickness on CTA.
BACKGROUND AND PURPOSE Carotid intraplaque hemorrhage is associated with stroke, plaque thickness, stenosis, ulceration, and adventitial inflammation. Conflicting data exist on whether calcification is a marker of plaque instability, and no data exist on adventitial calcification. Our goal was to determine whether adventitial calcification and soft plaque (a rim sign) help predict carotid intra...
