目的 对比分析普通 CT与螺旋 CT(SCT)对胰腺肿瘤患者的检查结果 ,探讨胰腺癌诊断及手术可切除性问题 ,提高对早期诊断的认识 .方法 将 38例经临床和病理检查确诊的胰腺癌患者分为普通 CT组 2 3例 ,SCT组 15例 .分别观察肝脏、腹腔、淋巴结转移和邻近大血管受侵犯情况 .两组患者检查结果作对比 ,手术切除病例与术前 CT检查结果作对比 .结果 CT检查结果比较 :SCT组肿瘤侵犯转移征象检出率明显高于 CT组 (P<0 .0 1) .CT检查与手术结果比较 :术前判断可切除肿瘤的准确率 SCT(88% )组明显高于 CT(6 0 % )组 .结论 比较研究发现 SCT较普通 CT分辨率高 ,能够更清楚地表现胰腺肿瘤的形态特征及其周围征象 ,能够反映胰腺癌侵犯转移征象 ,从而更准确地预测肿瘤病灶的可切除性 .
OBJECTIVE: To compare and analyze the results of routine CT and spiral CT (SCT) in the diagnosis of pancreatic cancer and explore the diagnosis and surgical resectability of pancreatic cancer and improve the understanding of early diagnosis.Methods Thirty-eight cases of pancreatic cancer confirmed by clinical and pathological examination Patients were divided into general CT group of 23 cases, SCT group of 15 cases were observed in the liver, abdominal cavity, lymph node metastasis and adjacent major vessel invasion violations of the two groups of patients for comparison, surgical resection and preoperative CT examination results for comparison .Results Comparing the results of CT examination: The detection rate of tumor invasion and metastasis in SCT group was significantly higher than CT group (P0.01) .CT examination and surgical results: The accuracy of preoperative tumor resection SCT (88% ) Group was significantly higher than that of CT (60%) group.Conclusions The comparative study shows that the resolution of SCT is higher than that of normal CT, which can more clearly show the morphological features and peripheral signs of pancreatic cancer, and can reflect the signs of invasion and metastasis of pancreatic cancer Accurately predict the resectability of tumor lesions.
