We employed 3D reconstruction of CT images for evaluation of hepatic injuries in a series of eight trauma patients. One had additional reconstruction of a renal injury. 3D imaging provided precise anatomical delineation of damaged areas, particularly in relation to major vessels. Moreover, the imaging agreed with operative findings in every case. The 3D reconstruction facilitated decisions regarding intraoperative, reoperative and non-operative management. The improved imaging provided by 3D reconstruction may allow hepatic CT scans to be interpreted with greater ease and accuracy than conventional CT. We believe this is the first report of its use in liver trauma. Current indications may include postoperative confirmation of the extent of hepatic injuries, assessment before reoperation, and contribution to decisions regarding non-operative management. A limitation at present is the time taken for image production, but we suggest that in the future 3D imaging might contribute to evaluation before emergency surgery in patients with abdominal injuries.
我们采用CT图像的三维重建技术，对一系列8例创伤患者的肝损伤情况进行评估。其中1例患者还对肾损伤进行了额外的重建。三维成像能够精确显示受损区域的解剖结构，特别是与主要血管的关系。此外，在每一例中成像结果与手术所见均相符。三维重建有助于做出关于术中、再次手术及非手术治疗的决策。三维重建提供的改进成像可能使肝脏CT扫描比传统CT更容易、更准确地解读。我们认为这是其在肝外伤中应用的首例报道。目前的适应证可能包括术后确认肝损伤的程度、再次手术前的评估以及有助于做出非手术治疗的决策。目前的一个局限是图像生成所需的时间，但我们认为未来三维成像可能有助于对腹部损伤患者进行急诊手术前的评估。
