Objective to study the value of multislice CT angiography (MSCTA) in the pre operative assessment of vascular involvement in pancreatic carcinoma. Methods 33 cases with pathologically proven pancreatic carcinoma underwent MSCTA prior to surgical intervention. The MSCTA findings in each of the 33 patients were evaluated prospectively by four radiologists. Vascular involvement of pancreatic carcinoma was validated at the time of surgery, which was a reference standard for comparison. Correlation was made...

Objective to study the value of multislice CT angiography (MSCTA) in the pre operative assessment of vascular involvement in pancreatic carcinoma. Methods 33 cases with pathologically proven pancreatic carcinoma underwent MSCTA prior to surgical intervention. The MSCTA findings in each of the 33 patients were evaluated prospectively by four radiologists. Vascular involvement of pancreatic carcinoma was validated at the time of surgery, which was a reference standard for comparison. Correlation was made between MSCTA findings and surgical results. Results 11 out of 33 cases with pancreatic carcinoma were considered to be resectable by MSCTA with a positive predictive value of 82% in comparison with surgical findings. MSCTA also had high correlation with surgical results in assessing the non resectability of pancreatic carcinoma (positive predictive value=95%). Conclusion MSCTA could delineate the vascular involvement of pancreatic carcinoma with high accuracy and provided valuable information in the preoperative assessment of pancreatic carcinoma.

目的 采用多层螺旋CT血管造影 (MSCTA)检查对胰腺癌周围血管侵犯情况以及肿瘤手术可切除性进行前瞻性评价 ,以确定其临床应用价值。方法 对 4 1例胰腺癌进行术前MSCTA检查 ,以多平面重建 (MPR)、最大密度投影 (MIP)等重建技术结合横断面图像显示胰腺癌及其胰腺周围血管 ,根据胰腺癌对周围血管的侵犯情况作出能否切除的术前评价。以手术结果作为金标准进行对照和分析 ,评价MSCTA在胰腺癌术前可切除性评估的临床应用价值。结果  33例胰腺癌患者接受了手术治疗 ,其中 11例术前MSCTA认为可切除 ,实际术中切除 9例 ,MSCTA评估可切除准确度为 82 % ;另 2 2例术前MSCTA评估为不可切除 ,实际手术无法切除 2 1,MSCTA评估不可切除准确度为 95 %。进行统计学检验分析 ,Kappa值为 0 .79,提示MSCTA术前评估结果与手术结果一致性较好。结论MSCTA术前评价胰腺癌及其周围血管侵犯程度具有相当高的正确性 ,对于胰腺癌术前可切除性评估具有重要的临床参考价值。

Objective To study the value of CT in the diagnosis and assessment of the resectability of the pancreatic cancer.Materials and Methods The CT appearances of 40 patients with suspicious pancreatic cancer,who were performed surgery,were reviewed.The diagnosis and assessment of respectability of pancreatic carcinoma was made prospectively by two radiologists based on CT images,according to the international comparable standards of pancreatic cancer.The results for the diagnosis and assessment of respectability of pancreatic carcinoma from CT images were compared with those from surgery and pathology.Results a mong the 40 patients,there were 35 patients with and 5 patients without pancreatic carcinoma confirmed by pathology.The accuracy of CT diagnosis for pancreatic carcinoma was 87.5% (35/40).In the 35 patients with pancreatic cancer,31 patients showed pancreatic masses on CT images,and 4 patients did not.The accuracy of CT assessment for peripancreatic vascular invasion,gastroenteric invasion,lymphadenopathy,liver metastases,and peritoneal carcinomatosis by pancreatic carcinoma were 84.0% (21/25),60% (6/10),81.0% (17/21),72.7% (8/11) and 55.6% (5/9),respectively.The positive and negative predictive values for the resectability of pancreatic carcinoma were,respectively,70% (7/10) and 92.0% (23/25) in CT images comparied with surgical findings.The kappa value was 0.64 between the pre-operative assessment by CT and by surgery.Conclusion; CT is accuracy in the diagnosis of pancreatic carcinoma and in the assessment of lymphadenopathy and peripancreatic vascular invasion by pancreatic carcinoma.It is also valuable in the assessment of the resectability of pancreatic carcinoma.

目的探讨CT在胰腺癌的诊断及手术可切除性评估中的价值。方法回顾性分析40例拟诊胰腺癌随后又行手术治疗患者的CT征象,并与手术病理结果对照。根据国内外CT对胰腺癌的诊断及术前可切除性评价的标准,判断胰腺癌的手术可切除性。结果40例中,胰腺癌35例,非胰腺癌5例。CT诊断准确性87.5%(35/40)。35例胰腺癌中,CT发现胰腺肿块31例,4例未发现肿块;周围结构侵犯、转移情况:25例胰周血管侵犯,CT诊断21例(84.0%);胃肠道侵犯10例,CT诊断6例(60.0%);21例淋巴结肿大,CT诊断17例(81.0%);11例肝转移,CT诊断8例(72.7%);9例腹膜转移,CT诊断5例(55.6%)。10例术前认为可切除,实际术中切除7例,可切除准确度70%;25例手术前认为不可切除,实际手术不可切除23例,不可切除准确度92%,进行统计学分析,Kappa值为0.64。结论CT可准确诊断胰腺癌、淋巴结转移及胰周血管侵犯。CT对胰腺癌的手术可切除性判断也有较大的价值。
