    This paper summerizes 93 cases of pancreas carcinoma demonstrated by CT scan and pathologtcal examination, emphasizing the CT diagnosis of the small pancreas, carcinoma less than 3cm. It showed that the varistion of the contour and the substantial appearance of the pancreas. the irregular and mildly increasing or the little local elevation of the pancreas head, the variation of the processus uncinatus as changed roundly and swellingly, the distention of the pancreas duct and the bile duct were the important sings of the early pancreas carcinoma. It indicates that the dynamic thin CT scan is an effective method to discover and to diagnose the early pancreas carcinoma. The assured rate is 83. 3%.

    To evaluate dualphase helical CT for detection and staging of pancreatic adenocacinoma, dualphase helical CT was performed on 36 patients with pancreatic adenocacinoma with a 95100ml bolus injection of contrast material at 3ml/s. Pancreatic phase(PP) and portal venous phase(PVP) began at 30 seconds and 65 seconds after the infusion of contrast material. The results showed that tumorpancreas contrast was significantly greater in PP(61.2715.43Hu) than in PVP(51.519.77Hu) (P<0.05), while mean value of pancereatic...

    To evaluate dualphase helical CT for detection and staging of pancreatic adenocacinoma, dualphase helical CT was performed on 36 patients with pancreatic adenocacinoma with a 95100ml bolus injection of contrast material at 3ml/s. Pancreatic phase(PP) and portal venous phase(PVP) began at 30 seconds and 65 seconds after the infusion of contrast material. The results showed that tumorpancreas contrast was significantly greater in PP(61.2715.43Hu) than in PVP(51.519.77Hu) (P<0.05), while mean value of pancereatic enhancement was 71.1014.79Hu in PP and 61.0110.41Hu in PVP (P<0.05). The enhancement values of major peripancreatic arterial structure were greater in PP than in PVP. The positive predictive values of the tumors was 100%, while the negative predictive values was 71.43%. The sensitivity and the accuracy were 93.55% and 94.44% respectively. Generally, dualphase helical CT could delineate pancreatic adenocarcinoma clearly. The tumorpancreas contrast was more conspicuous in PP than PVP. In addition, dualphase helical CT could afford more information for the assessment of resectability of pancreatic adenocarcinoma.

    为比较螺旋CT胰腺期和门脉期双期增强扫描在胰腺癌诊断和分期上的作用,对36例胰腺癌患者行螺旋CT双期增强扫描,扫描延迟时间:胰腺期(PP)为30s,门脉期(PVP)为65s,造影剂用量95~100ml,注射速度3ml/s。结果显示正常胰腺组织增强值胰腺期和门脉期分别为71.10±14.79Hu和61.05±10.41Hu(P<0.05),肿瘤-胰腺对比胰腺期和门脉期分别为61.27±15.43Hu和51.5±19.77Hu(P<0.05),肿瘤可切除性的PPV为100%,NPV为71.43%,敏感性和准确性分别为93.55%和94.44%。表明螺旋CT双期增强扫描能更清晰地显示胰腺癌,胰腺期肿瘤-胰腺对比较门脉期更显著,同时还有利于肿瘤可切除性的估价及小胰腺癌的检出。

    Objective To study the protocols of dual phase spiral CT for the evaluation of pancreatic carcinoma. Methods One hundred and four patients(44 with pancreatic carcinoma, 60 with no upper abdominal disease) underwent dual phase spiral CT. In group A, 40 patients were scanned for arterial and portal phase (20 and 60 s after intravenous infusion of contrast material at 3 ml/s) .In group B, 64 patients were scanned for pancreatic and hepatic phase(35 and 70 s). Mean CT attenuation value was obtained for normal pancreatic parenchyma, lesions and major peripancreatic blood vessels,respectively. The display rate of the small peripancreatic veins was calculated in the pancreatic and hepatic phase. All data were statistically analyzed. Results In normal group, enhancement value of pancreas during the pancreatic phase was the greatest of all phases [(118 10±17 78) HU, P <0 05]. Major peripancreatic vascular structures were visualized well in the pancreatic phase. The display rate of the small peripancreatic veins was higher in the pancreatic phase than in the hepatic phase ( P <0 05). In abnormal group, the tumor to pancreas contrast difference was also the greatest during the pancreatic phase [(65 89±28 81) HU, P <0 05]. Four cases of small cancer were found. It was identified that 54% of unresectable cases with major peripancreatic vessels invasion, 42% with small peripancreatic veins dilation, and 37% with metastatic hepatic neoplasms. Conclusion In the dual phase spiral CT protocol for pancreas, pancreatic and hepatic phase could be an optimal selection. It had an important value in diagnosing pancreatic carcinoma.
