目的：探讨多层螺旋CT（MSCT）后处理重建技术对小儿肠套叠诊断的价值。方法分析47例空气灌肠整复或手术证实肠套叠MSCT表现，所有病例均多平面重建（MPR）、曲面重建（CPR）重组，测量套叠肠管长度及管壁肿胀厚度。结果横轴面显示靶征43例，彗星尾征伴肾形肿块23例，结合MPR显示靶征47例（100%）、彗星尾征伴肾形肿块33例（70.2%）。整复成功36例，失败9例。成功组套叠肠管长（8.20±3.06）cm，厚（0.81±0.29）cm，失败组：长（12.15±0.26）cm，厚（1.47±0.28）cm。2组比较差异有统计学意义（t 长=3.8360，t 厚=6.1456，P值均<0.01）。结论 MSCT多平面技术能提高套叠特征性征象显示率,套叠肠管长度及管壁厚度的测量，能帮助临床预测整复成功率，正确选择治疗方案。

Objective To investigate the value of multi-slice spiral CT (MSCT) with multi-planar reformation (MPR) and curve planar reformation (CPR) post-processing techniques in the diagnosis of infantile intussusception. Methods Retrospective analysis of the MSCT findings in 47 infantile intussusception, which confirmed by air enema or operation. The raw data was post-processed by MPR, and CPR, the length and the thickness of intussusceptions were measured and recorded. Results The direct signs of intussusception on axial images were"target sign"(43 cas-es) and "comet tail sign with kidney-like mass" (23 cases). While axial images in combination with MPR were used, more direct signs were revealed, including "target sign" (47 cases) and "comet tail sign with kidney-like mass" (33 cases). Thirty-six cases had successful operations, while 9 cases failed. The average length of intussusception was (8.20 ±3.06) cm, the thickness of hydropic intestinal wall was (0.81 ±0.29) cm in successful group. For unsuccessful group, the length of intussusceptions was (12.15 ±0.26) cm, the thickness of hydropic intestinal wall was (1.47 ±0.28) cm. The data of two groups were compared with two sample t-test, with the value tL=3.8360,tT=6.145 6,the difference had statistical significance (P<0.01). Conclusion MPR is useful to improve the detecting rate of specific signs of adult intussusception, and CPR and MPR provide important information for the diagnosis.
