摘　　要：目的　研究不同胰腺疾病的MR胰胆管成像 (MRCP)特征 ,探讨特征性表现及MRCP对胰腺疾病的诊断价值。方法　对 111例临床怀疑胰腺疾病的患者进行MRCP检查。MRCP扫描序列包括 :厚层快速自旋回波 (TSE)序列和薄层半傅立叶采集单次激发快速自旋回波 (HASTE)序列 ,其中胰腺癌 4 6例 ,慢性胰腺炎 39例 ,壶腹周围癌 2 3例 ,胆总管结石 3例。结果　 (1) 37例胰腺癌、2 4例慢性胰腺炎和 12壶腹周围癌出现胰管改变 ,其中 33例胰腺癌、0例慢性胰腺炎和 12例壶腹周围癌出现胰管平滑扩张并中断 ,经统计学分析 χ2 =5 7 911,P <0 0 1;2例胰腺癌、2 3例慢性胰腺炎和 0例壶腹周围癌出现胰管不规则扩张且贯通病变区 ,经统计学分析 χ2 =6 0 343,P <0 0 1。 (2 ) 2 9例胰腺癌、10例慢性胰腺炎和 2 3例壶腹周围癌出现胆总管扩张 ,其中 2 9例胰腺癌、1例慢性胰腺炎和 2 3例壶腹周围癌出现胆总管扩张后截断 ,经统计学分析 ,χ2 =6 1 2 17,P <0 0 1。 (3) 2 9例胰腺癌、1例慢性胰腺炎和 12例壶腹周围癌出现双管征 ,经统计学分析 ,χ2 =34 6 5 4 ,P <0 0 1。 (4 ) 2 4例慢性胰腺炎、0例胰腺癌和 0例壶腹周围癌出现假性囊肿 ,经统计学分析 ,χ2 =5 4 5 93,P <0 0 1。结论　不同胰腺疾病有其相对应的特征性表现 。Objective To study the MR cholangiopancreatography (MRCP) characteristics of different pancreatic diseases, and to identify the diagnostic value of MRCP for pancreatic diseases.Methods One hundred and eleven patients with suspected pancreatic diseases underwent MRCP examination.The MRCP sequences included thick-slice turbo spin echo (TSE) and thin-slice half-Fourier acquisition single shot turbo spin echo (HASTE) sequences.The pancreatic diseases included pancreatic carcinoma (n=46), chronic pancreatitis (n=39), peri-ampullar carcinoma (n=23), and choledocholith (n=3).Results (1) The abnormal manifestation of pancreatic duct was observed in 37 cases of pancreatic carcinoma, 24 cases of chronic pancreatitis, and 12 cases of peri-ampullar carcinoma.Dilated pancreatic duct with smooth and regular caliber was observed in 33 cases of pancreatic carcinoma, 0 case of chronic pancreatitis, and 12 cases of peri-ampullar carcinoma, and statistical analysis showed significant difference (χ 2=57.911, P<0.01).Irregularly dilated pancreatic duct running through the lesion was observed in 2 cases of pancreatic carcinoma, 23 cases of chronic pancreatitis, and 0 cases of peri-ampullar carcinoma (χ 2=60.343, P<0.01).(2) Dilated common biliary duct was observed in 29 cases of pancreatic carcinoma, 10 cases of chronic pancreatitis, and 23 cases of peri-ampullar carcinoma.Dilated common biliary duct with sudden rupture was observed in 29 cases of pancreatic carcinoma, 1 case of chronic pancreatitis, and 23 cases of peri-ampullar carcinoma (χ 2=61.217, P<0.01).(3) Double duct sign was observed in 29 cases of pancreatic carcinoma, 1 case of chronic pancreatitis, and 12 cases of peri-ampullai carcinoma (χ 2=34.654, P<0.01).(4) Pseudocyst was observed in 24 cases of chronic pancreatitis, 0 case of pancreatic carcinoma and peri-ampullar carcinoma, (χ 2=54.593, P<0.01).Conclusion Different MRI characteristics were observed in various pancreatic diseases respectively.MRCP can show the subtle differences among the pancreatic di
