经冠脉CTA，冠脉磁共振(coronary magnetic resonance imaging, coronary MRI), OCT或IVUS等腔内影像，NIRS联合IVUS，可从不同角度观测到贯穿于心脏的各条蜿蜒曲折，宽窄不一的血管成像。若血管外弹力膜（extravascular elastic membrane, EEM）面积介于病变部位近端和远端EEM面积之间，则表示无血管重构。血管重构包括正性重构（positive remodeling）和负性重构（negative remodeling）, 若面积大于病变部位近端和远端EEM的面积，称为血管正性重构，反之当EEM面积小于病变部位近端和远端EEM面积，称为血管负性重构，参数上可通过重构指数，即病变部位EEM面积与近远端EEM面积平均值的比（Remodeling Index，RI）来表示，RI>1.0 表示正性重构， RI<1.0 表示负性重构。

经IVUS获得的有关血管正性重构的发生率、疾病表现及血管正性重构与临床预后间的关系的相关文献按发表时间排列如下，
