Clinical Application of Multi-Slice Spiral CT in Portal Vein Imaging

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.
