Evolving Concepts in the Diagnosis and Management of May–Thurner Syndrome

Journal of Clinical Interventional Radiology ISVIR, 2017
May–Thurner syndrome is a common cause of left lower extremity venous thrombosis resulting from repetitive and dynamic compression of the left common iliac vein by the right common iliac artery, commonly seen in young to middle-aged women.

The diagnostic role of IVUS in pelvic venous disease

Turkish Journal of Vascular Surgery, 2021
The two main mechanisms for pelvic venous disease (PeVD) are reflux of ovarian vein and obstruction of left common iliac or left renal vein. Some patients have a combination of the two.

CLASSIFICATION OF INTRAVASCULAR ULTRASOUND IMAGES BASED ON NON-NEGATIVE MATRIX FACTORIZATION FEATURES AND MAXIMUM LIKELIHOOD CLASSIFIER

International Journal of Advances in Signal and Image Sciences, 2018
The amount of plaque in coronary arteries in any particular point is identified by the IntraVascular UltraSound (IVUS) images. The classification of IVUS images is very important to diagnose various coronary artery diseases.

Diagnostic Performance of 60 MHz High-Definition Intravascular Ultrasound versus Fourier Domain Optical Coherence Tomography for Identifying Plaque Rupture, Plaque Erosion, and Thrombosis in a Rabbit Model

Reviews in Cardiovascular Medicine, 2023
Background: Most acute coronary syndromes occur due to coronary thrombosis caused by plaque rupture (PR) and plaque erosion (PE). Precise in vivo differentiation between PR and PE is challenging for intravascular imaging.
