Dynamic contrast-enhanced CT scan of Brain tumor: Analysis of peak enhancement time from type of brain tumor

Purpose To evaluate peak enhancement time from types of brain tumor by usmg of Smart prep Rx(auto bolus tracking)in dynamic contrast enhanced CT. Materials and Methods During May to August 2004, We studied 30 patients diagnosed with brain tumors. The number of persons were 13 in male and 17 in female. The patients were name of disease that 12 patients in Meningioma and 8 patients in Lymphoma and 4 patients in Germinoma and 6 patients in Metastasis(Adenocarcinoma). Our used Light speed Ultra 16(GE Medical System) detector rows 16, and slice thickness 2.5mm, number of images per rotation 8i with injection of total 100ml of contrast at the rate of 2ml a second. This imaging data was scanning a interval 5 second after 10 second and using of smart prep Rx in order to analysis of peak enhacement time. Results Average of peak enhancement time in each brain tumor was 90 second in Meningioma, 130 second in Lymphoma, 85 second in Germinoma, and 68 second in Metastasis(Adenocarcinoma). After injection of contrast media that appeared enhancement time differently a sort of tumor. Conclusion To measured peak enhancement time of brain tumors in preoperative contrast enhancement CT may be helpful in differential diagnosis of brain tumors, planning operative method and reducing rescan rate.
