To elucidate whether or not a newly developed technique in cinematic-displayed (cine) magnetic resonance imaging (MRI) can improve the semiquantitative evaluation of valvular regurgitant flow, 20 patients with valvular lesions were studied. Three pulse sequences of cine MRI, ie, standard, short echo time (TE), and rephasing scans, were compared with reference obtained by Doppler color flow mapping. Short TE technique and rephasing scan technique improved image quality remarkably as compared with standard technique. Each of the three cine MRI techniques showed good correlation with the Doppler method (p < 0.001). However, short TE and rephasing scan techniques gave a faithful estimation of the extent as compared with the Doppler method, whereas standard technique overestimated the regurgitation. Thus, cine magnetic resonance imaging with phase compensation technique can be utilized for the semiquantitative assessment of valvular regurgitation in a manner similar to that of Doppler color flow mapping.
为了阐明电影显示（cine）磁共振成像（MRI）中的一种新开发技术是否能改善瓣膜反流血流的半定量评估，对20例瓣膜病变患者进行了研究。将cine MRI的三个脉冲序列，即标准序列、短回波时间（TE）序列和重相位扫描序列，与通过多普勒彩色血流图获得的参考值进行比较。与标准技术相比，短TE技术和重相位扫描技术显著提高了图像质量。三种cine MRI技术中的每一种与多普勒方法都显示出良好的相关性（p < 0.001）。然而，与多普勒方法相比，短TE和重相位扫描技术能如实地估计反流程度，而标准技术则高估了反流情况。因此，具有相位补偿技术的cine磁共振成像可用于瓣膜反流的半定量评估，其方式类似于多普勒彩色血流图。
