中文摘要:
      目的 评价上消化道异位胰腺的MSCT多期增强扫描特征。方法 回顾性分析21例上消化道异位胰腺的MSCT形态学表现,观察异位胰腺与正常胰腺的增强特征,记录CT值,进行统计学分析。结果 21例异位胰腺均位于黏膜下,呈边界清楚、突向腔内的软组织影,17例(17/21,80.95%)呈圆形或类圆形,4例(4/21,19.05%)呈扁平丘状,中央凹陷征和小分叶征的检出率分别是28.57%(6/21)和85.71%(18/21)。平扫、增强扫描动脉期和门静脉期异位胰腺CT值均低于正常胰腺(P<0.05),但绝对强化值的比较差异无统计学意义(P>0.05)。平衡期异位胰腺与正常胰腺CT实测值比较差异无统计学意义(P>0.05),但绝对强化值异位胰腺高于正常胰腺(P<0.01)。动脉期及门静脉期异位胰腺与正常胰腺CT实测值均呈线性正相关(r=0.62、0.70,P均<0.01)。结论 上消化道异位胰腺MSCT增强特征与正常胰腺具有较好的一致性,MSCT增强扫描可作为诊断上消化道异位胰腺的重要检查技术。
英文摘要:
      Objective To quantitatively evaluate MSCT multiphase enhanced features of upper gastrointestinal heterotopic pancreas (HP). Methods MSCT morphological findings of upper gastrointestinal HP in 21 patients were analyzed retrospectively, and enhanced features of the heterotopic and normal pancreas were measured quantitatively. The CT value was also recorded and the statistical analysis was performed. Results All of the 21 HP were located in the submucosa with a well-defined soft tissue density mass protruding into the cavity. Seventeen cases (17/21, 80.95%) were round or oval and 4 cases (4/21, 19.05%) were flat-shaped. The detection rates of central umbilication sign and microlobulated contour sign were 28.57% (6/21) and 85.71% (18/21), respectively. The CT values of the HP in the unenhanced, enhanced arterial and portal venous phases were lower than those of the normal pancreas (all P<0.05), but there was no difference of the absolute enhancement values in both arterial and portal venous phases (both P>0.05). There was no difference of CT values between HP and normal pancreas in the equilibrium phase (P>0.05), but the absolute enhancement values of the HP were higher than that of the normal pancreas (P<0.01). The CT values of the HP had a positive linear correlation with that of the normal pancreas in the arterial and portal venous phases (r=0.62, 0.70; both P<0.01). Conclusion MSCT multiphase enhanced features of HP have good agreement with that of normal pancreas. Multiphase enhanced MSCT can be used as a valuable examination method for diagnosis of upper gastrointestinal HP.
