多层螺旋CT后处理技术在胰腺癌诊断及术前评估中的价值

摘要

目的:探讨多层螺旋CT(MSCT)后处理技术在胰腺癌诊断及术前评估中的价值.方法:回顾性分析22例胰腺癌病人的CT表现和临床资料,运用MSCT动态三期增强扫描及图像后处理技术,在肿瘤定位诊断基础上,观察周围组织结构受侵犯程度和转移情况;对其中12例行手术的胰腺癌胰周主要血管受侵情况进行术前评估并与手术结果比较.结果:22例胰腺癌中,周围血管受侵19例,胃十二指肠肠壁受侵4例,淋巴结转移6例,肝脾转移11例;CT评估主要血管受侵准确性为88.9%.结论:MSCT增强扫描结合后处理技术能够较准确诊断胰腺癌,为临床术前评估提供重要的参考价值.%Objective:To explore the value of MSCT post-processing technique in the diagnosis and preoperative evaluation of pancreatic cancer. Methods:The CT image and clinical data of 22 patients with pancreatic carcinoma were retrospectively analyzed. The infiltrating range of around organizational structure and distant metastasis of tumor based on tumor localization were observed using triple-phased scanning of contrast enhanced MSCT and post-processing technique. The preoperative assessment of 12 pancreatic cancer patients with major vascular invasion were compared with surgical outcome. Results:Among 22 cases,the peripheral vascular invasion in 19 cases,gastric and duodenal wall invasion in 4 cases,lymph node metastasis in 6 cases and hepatic or splenic metastasis in 11 cases were identified. The assessment accuracy in major vascular invasion was 88. 9% by MSCT. Conclusions:The contrast enhanced MSCT combined with post-processing technique can accurately diagnose the pancreatic carcinoma, which can provide an important value in preoperative evaluation in clinic.
