The Role Of Types Of The CT Arterial Hepatic Hemangioma: Clinical Application Of Interventional Therapyand Curative Effect Estimate

Objective Evaluation of dual-source 64-slice spiral CT 3-phase contrast-enhanced scanning and 3D post-processing of volume determination of liver hemangioma diagnosis; arterial phase enhancement the groups and types effect on the value of Clinical application.Methods 1)Retrospective analysis of clinical pathology by the 300 confirmed cases of hepatic hemangioma CT data.All cases applied for three dynamic enhanced scan and 3D-reprocessing. Determine the CT value of all cases of hepatic hemangioma in patients at different phases. 185 cases,according to the biggest diameter,we fall into 3 groups (4cm<d≦10cm,d>10cm,d<4cm),and using 3D software to determine enhanced capacity at different phases. Results 1)300 cases,452 lesions.In plain,91.82% of the lesions show low density lesions;8.18% lesions appear high or identical density leisons. And after enhanced scan, in the arterial phase, 92.78% of lesions appear nodular or patchy edge enhancement, 14.82% leisons have no enhancement; in the portal and the extension phase, the scope of the lesions increased gradually expanded,and the last appear epual density lesions。After 3D post-processing,in different angles and different phases,tumor volume changes that different morphological changes in the overall tumor and the relation of between liver hemangioma and liver artery。2) The diameter is less than 4.00cm of hepatic hemangioma in the arterial phase enhancement ratios are more than 28.00% with an average of 53.68±13.25%;4.0cm <d≦10.0cm hepatic arterial vascular tumor volume ratio of the enhanced 22.25%±3.25%;d>10.0cm hepatic arterial vascular tumor volume ratio of enhancement was less than 18.50%,,an average of 13.28%±4.26%。Conclusions①Dual-source 64-slice spiral CT CT 3-phase contrast-enhanced scanning and 3D post-processing clearly shows the typical CT hepatic hemangioma performance,and great value of vascular diagnosis and differential diagnosis。②For 4.0cm <d≦ 10.0cm hepatic hemangioma,arterial phase enhancement ratio of greater than 22.25% of the lesions,can be considered on its arterial blood supply (the rich blood supply type);less than 22.25% of the lesions,,can be considered its lack of arterial blood supply (lack of blood supply type);diameter of less than 4.00cm of hepatic hemangiomas are mostly rich blood supply type;d> 10.0cm hepatic hemangiomas mostly for lack of blood type。Dual-source 64-slice spiral CT three dynamic enhanced understanding of hepatic hemangioma scan the blood supply to the liver hemangioma embolization therapy。 Objective Analyze interventional treatment of liver hemangioma effect of different types。Methods Collected 32 patients of hepatic hemangioma undergo properative three dynamic contrast-enhanced scan.Measure tumor volume and ratio of arterial phase enhancement;apply the same density pingyangmycin-Iodine lotion to treat hepatic hemangioma in arterial embolization and follow-up and recheck CT after operation,measure the tumor volume,calculate the ratio of volume reducement and evaluate curative effect by statistical analysis. Results The difference of the tumor volume of all the cases before and after treatment by TAE were showed statistical significance. The difference of minification of tumor between the rich and lack blood-supply groups were showed statistical significance (P<0.05).But at d>10cm group,all 4 cases only undertake summary,effect is not very clear by arterial embolization.And for d<4cm group,because the patient choose follow-up observation. Conclusions 1)For 4cm <d≦10cm group,by arterial embolization,all kinds of hepatic haemangiomas have a good effect,and rich blood-supply is better.2)Dual-source 64-slice spiral CT has great value of effect assessment of after hepatic haemangiomas arterial embolization.
