目的 探讨多层螺旋CT(MSCT)重建技术在辅助诊断腹股沟疝中的应用价值.方法 回顾性分析佛冈县人民医院CT室2013年1月至2017年8月经手术证实的64例腹股沟疝患者的MSCT影像资料,包括疝囊解剖位置、走向、大小、形状以及不同层面扫描的影像数据,对比影像诊断结果 与手术结果.结果腹股沟斜疝MSCT表现为混杂密度或为囊实性,疝囊经腹股沟管进入阴囊或阴唇,疝囊颈位于腹壁下动脉外侧.腹股沟直疝MSCT表现为囊袋状或类半圆形软组织影,疝囊位置在腹股沟区但不下降进入阴囊,疝囊颈位于腹壁下动脉内侧.MSCT冠状位对腹股沟疝的结构显现更清楚,最接近手术结果,诊断正确率达95.31%,明显高于横断面的的84.38%,差异有统计学意义(P<0.05);矢状位诊断正确率为92.19%,也明显高于横断面,差异有统计学意义(P<0.05),而冠状位与矢状位间的诊断正确率比较,差异无统计学意义(P>0.05).结论 MSCT重建技术冠状位和矢状位重建成像可以提高腹股沟疝的诊断率.%Objective To explore the application value of multi-slice spiral CT (MSCT) reconstruction tech-nique in the diagnosis of inguinal hernia. Methods MSCT imaging data of 64 patients of inguinal hernia confirmed by surgery in the CT Room in People''s Hospital of Fogang County from January 2013 to August 2017 were retrospectively analyzed, including the anatomic location of hernia sac, direction and magnitude, shape, and image data of different lev-els of scan contrast, which were then compared with surgical results. Results The MSCT of inguinal hernia is charac-terized by mixed density or cysts. The hernia sac enters the scrotum or labia through the inguinal canal, and the neck of the herniation is located outside the inferior epigastric artery. MSCT showed direct inguinal hernia sac or semi circular soft tissue shadow, hernia position in the inguinal area but not descend into the scrotum, the hernia neck medial to the infe-rior epigastric artery. MSCT coronal structure of inguinal hernia appeared more clearly, the most close to the surgical re-sults, and the correct diagnosis rate was 95.31%, significantly higher than that of the cross section (84.38%), P<0.05. The correct rate of sagittal diagnosis was 92.19%, which was significantly higher than that of the transverse section (P<0.05), and there was no significant difference between coronal position and sagittal position (P>0.05). Conclusion Coronal and sagittal reconstruction imaging with MSCT reconstruction technique can improve the diagnostic rate of inguinal hernia.
