    In vivo detection of lipid-rich plaque by using a 40-MHz intravascular ultrasound: a comparison with optical coherence tomography findings

    iMAP™ has recently been introduced as a new tissue characterization method using the 40-MHz intravascular ultrasound (IVUS). However, few data have been published on the comparative findings of other imaging modalities in vivo. We examined 108 matched lesions from 70 patients (35 with stable angina and 35 with acute coronary syndrome) that underwent percutaneous coronary intervention (PCI) using pre-PCI OCT and IVUS. Identification of OCT-derived lipid-rich plaques and thin-cap fibroatheroma (TCFA) was performed using iMAP™. OCT-derived lipid-rich plaques and TCFAs were detected in 56 (51.8 %) and 20 (18.6 %) lesions, respectively. The iMAP™ analysis identified significantly greater percentage of ...
