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) cm^3,手术标本体积介于(163.26±81.9) cm^3,两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。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) cm^3 and(163.26±81.9) cm^3 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.
