摘　　要：目的:探讨胆囊内胆固醇结晶早期的MRI和B超的表现。方法:我院经MRI诊断100例胆固醇结晶的患者,全部进行了超声的检查,其中选择20例患者进食后再次进行MRI扫描,观察胆囊排空情况;B超确诊的30例胆固醇结晶的患者,30例同时进行了MRI的检查。结果:100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36例患者胆囊内的短T1高信号被完全抑制变为低信号,64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。100例患者在B超检查中有8例示胆囊附壁强回声。20例患者进食后再次进行MRI扫描,胆囊形态、大小无明显变化;B超确诊的30例胆固醇结晶患者,MRI检查显示胆囊内未见明显异常信号。结论:MRI对胆囊内胆固醇结晶早期是目前影像学唯一能够确诊的方法,B超只是对胆囊内胆固醇结晶晚期、形成息肉或结石后敏感性较高。MRI对胆囊结石形成早期的诊断明显优于超声诊断。Objective： Explore the gallbladder cholesterol clefts in early MRI and US performance. Methods： My courtyard diagnoses the patient who after MRI 100 example cholesterol crystallize, has carried on the US inspection completely, after chooses 20 example patients eat food, carries on the MRI scanning once more, observes the gallbladder evacuation situation; the ultrasound diagnosis＇s 30 example cholesterol crystallizes the patient, 30 examples have simultaneously carried on the MRI inspection. Results ：100 cases are visible in the gallbladder in patients with long short T1 T2 signals, STIR sequence of visible high signal is suppressed within the gallbladder becomes low signal, there were 36 cases of gall bladder in patients with short TI signals are completely inhibiting low signal, short T1 signals are partial inhibition of 64 cases, mainly is suppressed at the bottom of gallbladder, description of cholesterol deposited on the bottom. 100 cases of patients have been indicated in the check mural strong echoes of the gallbladder. 20 patients eat again after an MRI scan, shape, size, no significant changes of the gallbladder; b-confirmed in 30 patients with cholesterol crystals, MRI examination revealed no significant abnormal signal within the gallbladder; the cholesterol in the gallbladder polyps in patients with confirmed 20 cases, MRI scan shows no significant anomalies in the gallbladder. Conclusion： MRI in the gallbladder cholesterol crystal imaging only diagnosed early is the way on the formation of cholesterol crystal advanced within the gallbladder, polyps or higher sensitivity after the stones. MRI for early diagnosis is superior to ultrasound diagnosis of gallstone formation.
