摘要
目的:探讨海洛因体内藏毒的CT检出以及评价CT在筛查这类案例中的作用。方法:搜集2005年9月5日～2008年4月23日所有疑犯的影像学资料(所有病例均行CT检查,其中42例加做了腹部平片X线检查),回顾性分析最终确诊为海洛因体内藏毒罪犯的腹盆部CT影像学表现(形态、大小、数目、位置和密度)以及腹部X线平片的表现。结果:158例疑犯中124例最终确诊为海洛因体内藏毒者,这与CT检查结果一致。42例腹部平片检查中有2例假阴性结果。CT和腹部平片表现为腹盆部消化道和/或阴道内紧密排列的圆形或卵圆形肠道外异物影,此外还发现了"气环征"和"洋葱皮征"为海洛因体内藏毒的CT特征性表现,对检出这类罪犯有一定作用。结论:海洛因体内藏毒的CT表现具有一定特异性,常规腹盆部CT是检出体内藏毒疑犯的较为精确的一种影像学检查方法。
Objective：To determine the value of CT screening in detecting heroin packets hidden in body and to reveal the CT features.Methods：We collected 158 cases of suspected drug packers＇ imaging materials（all underwent CT,42 cases were imaged using plain X-ray film） from September 5th,2005 to April 23rd,2008.Abdominal-pelvic CT appearances（shape,size,number,location and density） and abdominal plain X-ray film manifestations were retrospectively observed for those who were finally confirmed as heroin body packers through the passing of evacuated drug packets.Results：Among 158 cases of suspected drug packers in our study,124 cases were finally diagnosed as heroin body packers.This was consistent with the CT results.However,there were 2 false-negative cases of abdominal imaging taken with plain X-ray film.All of the evacuat-ed heroin body packets were produced mechanically.CT and plain film characteristic findings included the presence of uni-form shape,varied density,and well-defined round or ovoid intra-luminal foreign-body shadows arranged closely along the gastrointestinal tract and/or vagina.We also found that the ＂air-ring sign＂ and ＂onion sign＂ were valuable characteristics that were seen on the CT scan,which helped to positively confirm the detection of heroin packets.Conclusion：Heroin body packing has clearly defined diagnostic features that can be seen with CT.Furthermore,conventional abdominal-pelvic CT is the imaging modality of choice in the evaluation of suspected body packers.
