[摘要]目的:探讨用体外线圈行前列腺波谱检查的应用价值。材料和方法:在3.0T(Tesla,特斯拉)磁共振条件下,仅采用体外线圈对29例正常男性志愿者进行多体素质子磁共振波谱分析(H-1magneticresonancespectroscopy,1HMRS),计算每个体素的(Cho+Cr)/Cit比值,分析青年组(≤40岁,11例)、中年组(41岁~60岁,9例),老年组(>60岁,9例)基底部、中部、尖部内腺及外周带的1HMRS特点。结果:(1)所有志愿者均顺利完成前列腺MRS检查,均能获得有诊断意义的谱线,图像质量佳,信噪比高。(2)青年组、中年组内腺比值高于外周带;三组间外周带比值无统计学差异;青年组外周带不同部位比值间有显著差异。结论:仅采用体外线圈在3.0T磁共振条件下能顺利完成前列腺MRS检查并获得有诊断意义的波谱信息,该法较之1.5T磁共振加直肠内线圈检查时间明显缩短,操作简便,被检者无痛苦,适用于不同年龄尤其是老年患者的前列腺MRS检查。
