目的我们评估动脉粥样硬化斑块的分布和成分在分叉血管内超声虚拟组织学（IVUS-VH）和多探测器计算机断层扫描（MDCT）的分叉角（BA）的关系。方法和结果在33例患者（年龄63 +/- 11岁，79%男性）与IVUS-VH和MDCT成像，33分叉匹配和研究。将分析的主血管分为5 mm近端段、分叉段和5 mm远端段。在MDCT和IVUS-VH上手动追踪斑块轮廓。具有>10%融合坏死核心的斑块，
Aims We evaluated the distribution and composition of atherosclerotic plaques at bifurcations with intravascular ultrasound-virtual histology (IVUS-VH) and multidetector computed tomography (MDCT) in relation to the bifurcation angle (BA).Methods and results In 33 patients (age 63 +/- 11 years, 79% male) imaged with IVUS-VH and MDCT, 33 bifurcations were matched and studied. The analysed main vessel was divided into a 5 mm proximal segment, the in-bifurcation segment, and a 5 mm distal segment. Plaque contours were manually traced on MDCT and IVUS-VH. Plaques with >10% confluent necrotic core and
