Aim: To study the protocols of dual-phase spiral CT for the evaluation of pancreatic carcinoma. WTHZMethods:WTBZ Sixteen patients were undergone examination of dual-phase spiral CT. The patients were scanned for both arterial and portal phases(25 s and 60 s after intravenous administration of 80-100 mL contrast material at 3 mL/s). The mean CT value was obtained for normal pancreatic parenchyma and tumor, respectively. The density difference between tumor and pancreatic parenchyma was evaluated. Peripancreatic...

Aim: To study the protocols of dual-phase spiral CT for the evaluation of pancreatic carcinoma. WTHZMethods:WTBZ Sixteen patients were undergone examination of dual-phase spiral CT. The patients were scanned for both arterial and portal phases(25 s and 60 s after intravenous administration of 80-100 mL contrast material at 3 mL/s). The mean CT value was obtained for normal pancreatic parenchyma and tumor, respectively. The density difference between tumor and pancreatic parenchyma was evaluated. Peripancreatic blood vessels were observed and evaluated. WTHZResults:WTBZ In the arterial and portal phases, the mean CT values were 47±8 HU and 53±10 HU for pancreatic tumors, 109±16 HU and 76±13 HU for normal pancreatic parenchyma, respectively. The density difference between tumor and normal pancreas in the arterial phases was significantly more than that in the portal phase (P<0.01). Peripancreatic artery invasion was visualized well in the arterial phase. The vein invasion was visualized well in the portal phase. Conclusion: The density difference between tumor and normal pancreas can be well depicted by spiral CT. Vascular invasion can be evaluated much more completely by combining arterial and portal phase. There is an important value of spiral CT in the diagnosis of pancreatic carcinoma.

目的 :探讨螺旋CT双期增强扫描诊断胰腺癌的价值。方法 :16例胰腺癌患者行螺旋CT双期增强扫描 ,动脉期延迟 2 5s,门静脉期延迟 60s ,以 3mL/s团注造影剂 80~ 10 0mL。测量肿瘤和正常胰腺组织的CT值 ,计算肿瘤 -胰腺密度差 ,同时对胰腺周围血管进行观察评价。结果 :肿瘤的平均CT值动脉期和门静脉期分别为 (4 7± 8)HU、(5 3± 10 )HU ;正常胰腺动脉期和门静脉期的CT值分别为 (10 9± 16)HU ,(76± 13)HU ;肿瘤 -胰腺密度差动脉期和门静脉期各为 (70± 18)、(2 3± 12 )HU ,二者差异明显 (P <0 0 1)。胰周动脉侵犯在动脉期显示好 ,静脉侵犯在门静脉期显示好。结论 :螺旋CT双期增强扫描动脉期可获得最大的肿瘤 -胰腺密度差 ,动脉期结合门静脉期对胰周血管侵犯的评价更全面 ,提高了胰腺癌手术可切除性评价的准确性。

Objective:To evaluate dual phase spiral CT scanning enhancement via arteries in assessing the resectability of pancreatic head cancer.Methods:Tumor resectability was prospectively evaluated in 18 patients proven pancreatic head cancer.The results of dual phase spiral CT scanning enhanced via arteries and those enhanced via veins were compared.Results:Fifteen of 18 patients had nonresectable disease,while three had resectable tumor,both dual phase spiral CT scanning enhanced via arteries and via veins were correct in assessing the resectability.Spiral CT scanning enhanced via arteries correctly predicted all the nonresectable cases and enhanced via veins only correctly predicted 12 cases.In assessing vascular involvements,dual phase spiral CT scanning enhanced via arteries showed superiority to that enhanced via veins.Conclusion:Dual phase spiral CT scanning enhanced via arteries is superior to that via veins in assessing the resectability of pancreatic head cancer.

目的:采用经动脉插管双期螺旋CT扫描的方法,对胰头癌的可切除性进行评价。方法:对18例胰头癌行经动脉插管后双期螺旋CT增强扫描,动脉期扫描时间为10s,门静脉期50s,扫描速度2.5ml/s,造影剂为欧乃派克300或优维显30030ml,用0.9%生理盐水稀释至100ml,通过留置导管注入造影剂于肠系膜上动脉。扫描结果和经静脉双期扫描进行对比。结果:18例胰头癌,可行根治切除3例,不可根治切除15例。对于3例可行根治切除的,两种方法均做出了正确判断,15例不可根治手术者经动脉插管双期螺旋CT扫描作出了正确判断,而经静脉双期扫描只正确判断了12例。估计手术无法切除率经动脉双期扫描为83%(15/18),经静脉双期扫描为67%(12/18)。在判断胰周血管是否受侵的准确性方面,经动脉插管法优于静脉法。结论:经动脉插管双期螺旋CT扫描能够较经静脉双期扫描更准确地评价胰头癌的情况,有利于肿瘤可切除性的评价。
