摘要
目的探讨多层螺旋CT门静脉成像的临床应用价值。方法应用GE Light SpeedQX/i4 CT机对137例行CT增强扫描者的CT图像进行门静脉成像,并分析其结果。137例中,肝癌46例,肝硬变20例,肝海绵状血管瘤21例,肝脓肿9例,胆囊癌6例,胆管癌14例,胰腺癌16例,正常5例。结果门静脉期成功显示门静脉、肠系膜上静脉及脾静脉者109例,其中容积再现图像显示清晰者84例,最大密度投影及多平面重建图像显示清晰者109例。显示门静脉高压45例,侧支循环开放18例,门静脉癌栓15例,单独脾静脉癌栓1例,巨大海绵状血管瘤6例。结论多层螺旋CT门静脉成像能较清楚地显示门静脉解剖及其病变,为临床医生制定正确的治疗方案提供依据。
Objective To study the clinical significance of multi-slice spiral CT in portal vein imaging.Methods One hundred and thirty seven cases underwent enhanced scan with GE Light SpeedQX/i4 CT scanner were collected,including 41 cases of liver cancer,20 cases of hepatic cirrhosis,21 cases of cavernous hemangioma of liver,9 cases of hepatic abscess,6 cases of carcinoma of gallbladder,14 cases of cholangiocarcinoma,16 cases of pancreatic carcinoma,and 5 cases in normal.The results of portal vein images were reconstructed with three-dimensional software and analyzed.Results In 109 cases,portal vein,cranial mesenteric vein,and splenic vein were demonstrated successfully in the stage of portal vein： volume rendering images were clear in 84 cases,and maximum intensity projection images and multiplanar reconstruction images were clear in 109 cases.Forty-five cases of portal hypertension,18 cases of opened collateral circulation,15 cases of portal vein tumor thrombus,1 case of splenic vein tumor thrombus,and 6 cases of large cavernous hemangioma were demonstrated successfully.Conclusion The portal vein imaging with multi-slice spiral CT can show the dissection and lesions of portal vein and its branches clearly,and can provide the clinical evidence for clinicians to formulate a treatment plan correctly.
