【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。
[Abstract]:Objective: to investigate the CT detection of heroin and to evaluate the role of CT in screening such cases. Methods: the imaging data of all the suspects from September 5, 2005 to April 23, 2008 were collected. Among them, 42 cases were examined with plain abdominal radiography. The CT findings (shape, size, number, location and density) of abdomen and pelvis (shape, size, number, location and density) of the criminal who was finally diagnosed as drug collector in heroin were analyzed retrospectively. Results of the 158 suspects, 124 were finally diagnosed as heroin addicts. This was consistent with CT findings. 2 of 42 cases of abdominal plain film showed false negative results. Ct and plain film showed closely arranged circular or oval parenteral foreign bodies in the abdominal pelvic digestive tract and / or vagina. In addition, it was found that "gas ring sign" and "onion skin sign" were characteristic CT manifestations of drug hiding in heroin, which played a certain role in the detection of this kind of criminals. Conclusion: the CT manifestations of heroin are specific. Conventional abdominal and pelvic CT is a more accurate imaging method for detecting the suspected drug in heroin.
