目的：评价快速自旋回波（FSE）磁共振成像在肝脏和上腹部脂肪抑制和非脂肪抑制中的应用。材料和方法：常规自旋回波（SE）T2加权，FSE T2加权，对37例高度怀疑肝脏局灶性病变的患者进行了脂肪抑制FSE T2加权成像，定量分析表明脂肪抑制FSE成像具有最高的病变，肝脏对比噪声比;常规SE成像，最低。在定性分析中，首选FSE成像。在等级顺序分析中，就整体图像质量而言，83%的时间首选FSE成像，17%的时间首选脂肪抑制FSE成像;脂肪抑制FSE成像在64%的情况下是首选，FSE成像在23%的情况下是首选，常规SE成像13%结论FSE成像有或没有脂肪抑制是一种潜在的有用的脉冲序列，用于评估上腹部
PURPOSETo evaluate use of fast spin-echo (FSE) magnetic resonance imaging with and without fat suppression in the liver and upper abdomen.MATERIALS AND METHODSConventional spin-echo (SE) T2-weighted, FSE T2-weighted, and fat-suppressed FSE T2-weighted images from 37 patients strongly suspected to have focal hepatic lesions were evaluated.RESULTSQuantitative analysis demonstrated that fat-suppressed FSE imaging had the highest lesion-liver contrast-to-noise ratio; conventional SE imaging, the lowest. In a qualitative analysis, FSE imaging was preferred. In a rank order analysis, FSE imaging was preferred 83% of the time and fat-suppressed FSE imaging 17% of the time as regards overall image quality; fat-suppressed FSE imaging was preferred 64% of the time, FSE imaging 23% of the time, and conventional SE imaging 13% of the time as regards signal abnormality detection.CONCLUSIONFSE imaging with and without fat suppression is a potentially useful pulse sequence for evaluating the upper abdomen.
