This study investigated the sonographic properties of drug packets containing narcotic drugs and the diagnostic role of ultrasonography in detecting body packing in comparison with CT.
Forty-five suspects admitted to our hospital for diagnosis and management were routinely evaluated by non-contrast CT for the presence of drug packets. A single radiologist blind to CT data independently performed the abdominal ultrasonographic scans.
Thirty-five of 45 suspects were carrying packets. In positive cases, two types of packets with different properties were noted. Twenty-eight cases had type 1 packets (solid form drug) and 7 had type 2 packets (liquid form cocaine). The sensitivity, specificity, positive, and negative predictive values of ultrasonography for detecting drug packets were 91%, 70%, 91%, and 70%, respectively. Ultrasonography accurately determined the presence or absence of packs in 39 of 45 suspects.
Ultrasonography was found to have a high sensitivity but a low specificity in suspected cases. A negative ultrasonography cannot rule out the diagnosis of body packing. However, it may be preferred as the initial imaging method or for follow-up of suspected cases as a radiation-free, easy-to-use, and inexpensive technique.
本研究调查了含有麻醉药品的药包的超声特性，以及与CT相比超声检查在检测体内藏毒方面的诊断作用。
对我院收治的45名因诊断和管理而入院的嫌疑人常规行非增强CT检查以确定是否存在药包。一名对CT数据不知情的放射科医生独立进行腹部超声扫描。
45名嫌疑人中有35人携带药包。在阳性病例中，发现了两种性质不同的药包。28例为1型药包（固体剂型药物），7例为2型药包（液体剂型可卡因）。超声检测药包的敏感性、特异性、阳性预测值和阴性预测值分别为91%、70%、91%和70%。超声准确判断了45名嫌疑人中39人的药包情况。
在疑似病例中，超声检查敏感性高但特异性低。超声检查结果为阴性不能排除体内藏毒的诊断。然而，作为一种无辐射、易于使用且成本低廉的技术，它可能更适合作为初始成像方法或用于疑似病例的随访。
