摘要

方法:选取25例颈动脉狭窄患者，其中颈动脉狭窄率为70%，有临床适应症，需行动脉内膜切除术。血管造影(AngioMRI)用于评估斑块内出血(Cube序列)。获取PAI片段(5秒，帧率1000/秒，每个患者3 - 15个)。通过综合评分系统(半定量，从0到12)对每个片段是否存在PAI信号进行评分。采用半定量分级量表评估出血斑块的组织学特征和易损性。

P.46 Assessment of Intraplaque Hemorrhage by Photoacoustics Imaging (PAI): First in-vivo Human Validation Study

Methods: 25 patients with carotid stenosis>70% and clinical indication to tromboendoarterectomy were recruited. AngioMRI for intraplaque hemorrhage assessment (Cube sequence) was performed. PAI clips (5 seconds, Frame rate 1000/sec, 3 to 15 per patient) were acquired. Each clip was scored for the presence of PAI signal by means of an integrated scoring system (semiquantitative, from 0 to 12). Semiquantitative grading scales were used to assess plaque histological features of hemorrhage and vulnerability.
