The clinical application valuation of three dimensional imaging with 64-slice spiral CT in primary hepatic carcinoma therapy

Objective:To study the clinical application and valuation of three dimensional imaging with 64-slice spiral CT in primary hepatic carcinoma therapy.Methods:The 97 patients of primary hepatic carcinoma were scanned with arterial phase and portal vein phase enhancement,the maximum projection,multi-planar reformation and volume rendering were performed.Results:The three dimensional imaging of 97 patients of primary hepatic carcinoma were displayed.The tissue and vessels of 69 patients were not invaded by tumors,the adjacent vessels of 19 patients were oppressed by tumors,the hepatic artery variation of 38 patients(39%),the fistula of hepatic artery and portal vein(HAPF) in 16 patients,the portal tumor embolus of 11 patients,merging with hepatic cirrhosis of 71 patients,the portal sponge degeneration of 2 patients.The 67 patients were treated by surgery except of the TACE therapy of 30 patients,there were 63 patients in coincidence with the surgery exploration results,the accurate ratio was 95.5%.There were no significant deviation with DSA and three dimensional imaging under 3-grade hepatic artery branch,The three dimensional imaging were lower than DSA above 4-grade of hepatic artery branch,were identical with DSA in feeding artery,tumor vessel and vessel variation.Conclusion:The size,shape and encroachment scope could be showed with three dimensional imaging of 64-slice spiral CT,especially the tumors and the vessels of liver could be evaluated perfectly,the variation of liver vessels were understood thoroughly.There was important value for conducting the surgery and intervention treat.
