摘要目的：探讨PET-CT在肝脏泡型棘球蚴病灶体积测量中的应用，旨在提高影像学对手术方案的指导性作用。方法：收集肝脏泡型棘球蚴病15例，术前行PET-CT检查，用PET-CT软件测量病灶体积。经PET-CT医师与外科医师共同讨论制定可能的手术方案，分析预切除体积，测量出手术标本的实际体积；将预切除体积与手术标本体积间进行统计学分析。结果：本组15例患者中，预切除肝脏体积介于（163.59±82.1） cm3，手术标本体积介于（163.26±81.9） cm3，两者间差异无统计学意义（P=0.448）。术前病灶测量的体积与术后切下来的病灶测量的体积呈正相关（r=1，P=0.000 1）。15例患者23个病灶，依据术前制定的手术切除方案，所有病灶得以完整切除。结论：PET-CT对肝脏泡型棘球蚴病灶体积的测量，能够为临床施行精准病灶切除提供指导性的个体化影像学依据，值得临床推广应用。

Abstract：Objective: To explore the application of PET-CT in volume measurement of hepatic alveolar echinococcosis lesions, so as to improve the guiding role of imaging to surgery plans. Methods: Fifteen patients of hepatic alveolar echinococcosis underwent examination by PET-CT and the lesion volume was measured by PET-CT software before operation. The possible surgery plans were discussed and made. The predictive resection volume was measured and statistically analyzed with that of surgical specimens. Results: Out of the 15 cases, the volumes of the predictive liver resection and the operative specimen were (163.59±82.1) cm3 and (163.26±81.9) cm3 respectively, and there was no statistical difference(P=0.448). The volume of preoperative lesion was positively correlated with that of the postoperative(r=1, P=0.000 1). According to the operative resection plan established before surgery, 23 lesions in 15 patients were resected completely． Conclusion: Lesion volume measurement of hepatic alveolar echinococcus based on PET-CT could provide individual imaging basis for guiding precise lesion resection.
