【摘要】 目的探讨多排螺旋CT(MDCT)在胰腺癌术前评估中的价值。方法对53例经手术病理证实的胰腺癌患者进行MDCT扫描,结合多平面重组(MPR)、最大密度投影(MIP)、曲面重建(CPR)、容积再现(VR)等后处理技术,综合评价癌肿与周围主要血管、脏器的关系及肝脏、腹膜、腹腔淋巴结转移情况,对胰腺癌作出能否切除的术前评估。结果53例手术患者中,16例行根治性手术切除,14例术前判断正确,2例术前误判为不可切除,均为对肿瘤侵及血管的过度评价。37例行姑息性手术,5例误判为可切除。1例为腹腔淋巴结转移的漏诊,1例未提示肝内转移灶,3例为对肿瘤侵犯血管的低估。结论MDCT对胰腺癌术前可切除性的评估具有重要的临床指导意义。更多还原

【Abstract】 Objective To study the value of MDCT in the preoperative assessment of resectability in patients with carcinoma of pancreas.Methods 53 cases of pancreatic carcinomas with intact MDCT materials proved operation and pathology were collected.Combining the transverse images and multiplanar reformation(MPR),maximum intensity projection(MIP),curved planar reconstruction(CPR) and volume rendering(VR),the resectable possibility of tumors were evaluated preoperatively,inclunding the relationship between tumors,vessels and organs,as well as metastases.Results Of 53 cases,16 had underwent radical resection,2 cases believed unresectable preoperatively,which were overestimating the degrees of vessels involved by tumors,37 cases had palliative operation,in which 5 cases were believed resectable preoperatively.Lymph node or liver metastases were missed in 2 cases and 3 cases were underestimating the degrees of vessels involved by tumor.Conclusion In evaluating the resectability of pancreatic carcinoma preoperatively,MDCT plays an important role.更多还原
