一站式多模态CT联合RAPID软件在急性缺血性卒中的应用

Application of Multimodal CT Combined with RAPID Software in Acute Ischemic Stroke

摘要: 目的：研究一站式多模态CT联合RAPID软件对急性缺血性卒中的诊断价值。方法：选取2020年1月~2021年02月于我院就诊的发病24小时内急性缺血性卒中患者作为研究对象，行一站式多模态CT检查并使用RAPID软件进行处理，分析RAPID图像特征。结果：共纳入98例急性缺血性卒中患者，大血管闭塞患者39例(39.79%)，大血管闭塞组首次头颅CT至发病时间、入院NIHSS评分、ASPECT评分、V_CBF<30%、VTmax>6s与非大血管闭塞组相比，差异具有统计学意义(P < 0.05)。前循环大血管闭塞组ASPECT评分、V_CBF<30%，V_Tmax>6s与后循环大血管闭塞组相比，差异具有统计学意义(P < 0.05)。结论：一站式多模态CT联合RAPID软件可快速诊断是否为急性大血管闭塞和大血管闭塞的部位，RAPID软件能够快速直观地计算ASPECT评分、V_CBF<30%、V_Tmax>6s，指导是否需要接受血管内治疗。

Abstract: Objective: To study the diagnostic value of multimodal CT combined with RAPID software in acute ischemic stroke. Methods: We extracted all ischemic patients within 24 hours of onset between January 2020 and February 2021. Patients who underwent multimodal CT examination and processed with RAPID software were analyzed. Results: A total of 98 patients were included, 39 patients (39.79%) with large vessel occlusion. There were significant differences between the large vessel occlusion group and the non-large vessel occlusion group in the time from the first head CT to the onset, NIHSS score, ASPECT score, V_CBF<30%, V_{Tmax>6 s} (P < 0.05). There were significant differences in ASPET score, V_CBF<30%, V_Tmax>6s between anterior large vessel occlusion group and posterior large vessel occlusion group (P < 0.05). Conclusion: Multimodal CT combined with RAPID software can quickly diagnose whether it is large vessel occlusion or not and the location of large vessel occlusion. RAPID software can furthermore quickly and intuitively calculate ASPECT score, V_CBF<30%, V_{Tmax>6 s} and guide endovascular treatment.
