PURPOSE
To evaluate use of fast spin-echo (FSE) magnetic resonance imaging with and without fat suppression in the liver and upper abdomen.
MATERIALS AND METHODS
Conventional 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.
RESULTS
Quantitative 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.
CONCLUSION
FSE imaging with and without fat suppression is a potentially useful pulse sequence for evaluating the upper abdomen.
目的
评估快速自旋回波（FSE）磁共振成像在肝脏及上腹部检查中使用脂肪抑制和不使用脂肪抑制的情况。
材料与方法
对37例高度怀疑有肝脏局灶性病变患者的常规自旋回波（SE）T2加权像、FSE T2加权像及脂肪抑制FSE T2加权像进行评估。
结果
定量分析表明，脂肪抑制FSE成像的病变-肝脏对比噪声比最高；常规SE成像最低。定性分析中，FSE成像更受青睐。在排序分析中，就整体图像质量而言，FSE成像在83%的情况下更受青睐，脂肪抑制FSE成像在17%的情况下更受青睐；就信号异常检测而言，脂肪抑制FSE成像在64%的情况下更受青睐，FSE成像在23%的情况下更受青睐，常规SE成像在13%的情况下更受青睐。
结论
使用和不使用脂肪抑制的FSE成像对于评估上腹部是一种潜在有用的脉冲序列。
