目的　探讨液体衰减反转恢复序列(fluid attenuated inversion recovery,FLAIR)与其他序列搭配在腹部疾病应用的临床价值，并初步评价其适用范围。　材料与方法　对36例腹部疾病患者共126个病灶进行定性，按常规扫描方法加上FLAIR序列进行检查，之后根据需要按照下列步骤进行扫描：(1)行质子像(PDW)； (2)多回波成像； (3)仅10例患者行静脉注射Gd-DTPA扫描。　结果　经FLAIR后病灶依信号强度分为3种：(1)高信号(病灶信号无改变)； (2)等信号； (3)低信号。分别为28个(22.22%)、27个(21.43%)、71个(56.35%)病灶。有102个病灶FLAIR明确诊断，占80.95%。24个行质子像、多回波成像定性。其中10例经增强扫描确定性质。低信号病灶均为囊性病变或液体，等信号病灶均为良性病变。　结论　FLAIR是90年代开发的MR成像新技术。腹部应用尚未见报道。在结果判定上以低信号组病例最具有诊断意义，等信号组均为良性病变，高信号组解释较为复杂。其优点有：(1)检查时间缩短； (2)能提高病灶的检出率； (3)病灶结构、性质易于判定； (4)减轻了患者的经济负担。

Objective　To evaluate FLAIR, combined with other sequences, in the diagnosis of abdominal diseases and its clinical applicable scope.　Materials and Methods　FLAIR and, if necessary, PDW, multi-echo sequence and/or Ga-DTPA enhanced scanning were performed in 36 patients with 126 abdominal localized lesions. MRI findings were analyzed and qualitative diagnosis was made.　Results　On FLAIR scans, the lesions displayed hig-intensity signal (n=28, 22.22%), or iso-intensity signal (n=27, 21.43%), or low-intensity signal (n=71, 56.35%). All the lesions showing iso-intensity signal were benign, while all the lesions showing low-intensity signal were cyst or fluid collection.　Conclusion　The authors consider that FLAIR has three advantages: (1) the whole procedure takes a very short time; (2) the detecting rate of the lesion is higher; and (3) the cost is low.
