摘　　要：目的:探讨胆囊内胆固醇结晶的MRI表现。方法:回顾性分析我院16例经MRI诊断为胆固醇结晶的患者,同时有10例行B超对比检查。结果:16例患者胆囊内均可见短T1长T2信号,STIR序列可见胆囊内高信号被抑制变为低信号,有3例患者胆囊内的短T1高信号被完全抑制变为低信号,13例短T1信号被部分抑制,主要是胆囊底部被抑制,说明胆固醇沉积在底部。10例患者B超检查示胆囊内未见明显异常。结论:低场强MRI对胆囊内胆固醇结晶有重要诊断价值,准确性明显高于B超。Objective：To discuss the manifestation of gallbladder cholesterol crystallization performed by MRI. Methods： Analysed 16 cases patients with cholesterol crystallization confirmed by MRI retrospectively, and 10 cases with the ultrasound contrast examination. Results： Sixteen patients were found within the gallbladder short T1 and T2 signal, STIR sequence saw gall- bladder high signal was inhibited into low signal. Short high T1 plete restraint; 13 cases short T1 signal were restrained by the signal in 3 cases gallbladders inner became low signal by compart, especially the gallbladder bottom, which indicated that cholesterin deposits in the bottom mainly; the ultrasound examination in 10 cases showed normal in the gallbladder Conclusion： Low field MRI is valuable in diagnosing gallbladder cholesterol crystallization , and the accuracy is better than ultrasound.
