目的研究64排螺旋CT多期扫描技术在胰腺癌诊断中的临床应用价值。方法对36例经手术病理证实的胰腺癌患者行上腹部全胰64排螺旋CT平扫和三期增强扫描。胰腺增强采取注射对比剂后18～30s、30～45s和60～70s动脉期、胰腺期、门脉期三个时相扫描。结果平扫时胰腺癌的实质部分一般呈现为等密度,增强表现则大多呈现为相对低密度。64排螺旋CT对胰腺癌不可切除的判断准确率高达100%,对可切除性判准确率82%。结论 64排螺旋CT三期扫描能反映胰腺癌的血供特征,可作为诊断胰腺癌及其术前分期的首选方法,并在判定不可切除性方面有一定价值。
Objective To study the clinical value of multislice spiral CT scan in the diagnosis of pancreatic cancer. Methods Thirty-six patients with pathologically confirmed pancreatic cancer underwent total abdominal plain CT 64-slice helical CT scan and three-phase enhanced scan. Pancreatic enhancement was taken at 18-30s, 30-45s and 60-70s arterial phase, pancreas phase, and portal phase after injection of contrast agent. Results The main part of pancreatic cancer during plain scan showed general density, while the enhanced performance mostly showed relatively low density. 64-slice spiral CT of unresectable pancreatic cancer to determine the accuracy of up to 100%, the excision of the sentence to determine the accuracy of 82%. Conclusion The three-phase CT scan of 64-slice spiral CT can reflect the characteristics of blood supply of pancreatic cancer, which can be used as the first choice for the diagnosis of pancreatic cancer and its preoperative staging. It has some value in determining the unresectability of pancreatic cancer.
