【摘要】 目的:探讨多螺旋CT判断胰腺癌可切除性的方法和标准。方法:我院2001年7月～2005年12月使用多螺旋CT对34例胰头癌患者进行术前薄层多期扫描,将胰周重要血管受侵犯程度分为5级,结合周围组织脏器的受累情况判断胰头癌的可切除性,并与手术结果相对照。结果:34例胰头癌患者术前17例判断可切除,实际15例得到根治性切除。灵敏度达88.2%,特异度达89.5%。结论:利用血管受侵犯分级Raptopoulos法结合传统的Freeny法,多螺旋CT可以较准确的判断胰头癌的可切除性,具有重要的临床意义。更多还原

【Abstract】 Objective: To study the standard and methods of resectability for carcinoma of head of pancreas using multihelical computed tomography (MHCT). Methods: From July 2001 to December 2005, MHCT was used for lamellar three-stage scanning on 34 patients with carcinoma of head of pancreas. The degree of invasion in major peripancreatic vessels was prospectively graded on a 0-5 scale and respectability of the carcinoma of head of pancreas was judged, based on involvement of contiguous organs around tumor. Results: The tumors can be removed in 17 of the 34 patients with carcinoma of head of pancreas, but radical resection was done in only 15 cases, with a sensitivity of 88.2% and a specificity of 89.5%. Conclusions: The resectability of the carcinoma of head of pancreas can be correctly judged by multihelical CT using the grading of vascular invasion of Raptopoulos in combination with the traditional grading method of Freeny. The clinical significance is apparent.更多还原
