OCT versus IVUS: accuracy versus clinical utility.
The technology of optical coherence tomography (OCT) has evolved from time-domain to frequencydomain imaging. Time-domain OCT is most often performed using proximal balloon occlusion; as such, dimensions are smaller than measured using intravascular ultrasound (IVUS), presumably due to diminished perfusion pressure. Conversely, frequency-domain OCT does not require proximal balloon occlusion, t...
متن کامل3T intravascular MRI, IVUS and OCT: A study in contrast.
Audience: Interventional radiologists and clinicians interested in intravascular imaging. Purpose: To compare, head-to-head, the performance of three intravascular (IV) imaging modalities—Ultrasound (IVUS), optical coherence tomography (OCT) and 3T MRI—for studying atherosclerotic and stented vessels. Atherosclerosis is marked by lesions which, with high extracellular lipid and thin fibrous cap...
متن کاملFusion of IVUS and OCT Through Semi-Automatic Registration
The most frequent cause of heart attack and sudden cardiac death is the disruption of plaque build ups in the arteries. Current technologies such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) image the vessels from inside-out in order to detect plaque deposits as well as other structures. In this work we develop a novel image fusion technique that produces images wit...
متن کاملIntegrated IVUS-OCT for real-time imaging of coronary atherosclerosis.
Accurate assessment of atherosclerotic plaque characteristics and the subsequent tailoring of optimal therapy holds great promise for preventing acute coronary syndromes (ACS) and life-threatening sequelae (1). Combined use of optical coherence tomography (OCT) and intravascular ultrasound (IVUS) was proposed as a potential method for accurate assessment of plaque characteristics and vulnerabil...
متن کاملAssessment of coronary atherosclerosis progression and regression at bifurcations using combined IVUS and OCT.
OBJECTIVES The aim of this study was to evaluate the progression of atherosclerotic coronary plaques at bifurcations, using combined intravascular ultrasound-virtual histology (IVUS-VH) and optical coherence tomography (OCT). BACKGROUND Pathological findings reveal that atherosclerotic plaques characterized by the presence of large necrotic cores (NCs) with fibrous cap thicknesses < 65 μm are...
