| 中文摘要:目的探讨螺旋CT对腹内疝的诊断价值。方法对7例CT诊断为腹内疝，并经手术证实的病例资料进行回顾性分析，CT检查采用平扫及双期增强，并进行了容积再现（VR）重组后任意切割、多平面重组（MPR）及最大密度投影（MIP）处理。结果7例腹内疝中，5例有腹部手术史，7例均表现为肠梗阻，其中4例合并小肠扭转显示肠管和血管的“漩涡征”，2例出现肠绞窄，表现为肠管强化减弱、肠壁水肿、腹腔积液；5例显示疝口，并有肠聚集、移位、肠系膜血管走形异常。 结论螺旋CT增强扫描和多种方法重组对腹内疝具有重要的诊断价值。 |

| Abstract:ObjectiveTo study the diagnostic value of helical CT on internal abdominal hernia.MethodsThe CT imaging findings of 7 cases of internal abdominal hernia which had been proved by operations were reviewed retrospectively.CT image examination was performed by the plan and double strengthening scan and Volume rendering (VR), Multi-planar reformation (MPR) and Maximum intensity Projection (MIP) were adopted.ResultsAmong the 7 cases of internal abdominal hernia, there were 5 cases with abdominal surgery histories.Intestinal obstructions were found in all of the 7 cases and volvulus were showed in 4 cases, which manifested the whirlpool-like sign of intestine and vessel.Otherwise, intestinal strangulation was found in 2 cases with reduced enhancement and edema of intestine wall and ascites.Orificium hernialis was observed in 5 cases which showed bowel clustering and displacement, changes of mesentery vessel.ConclusionThe enhanced helical CT scan and multi-image reconstruction method have much important value in diagnosing internal abdominal hernia. |
