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.

Purpose The author evaluated the coronary artery stenosis of using 64 volume cardiac CT angiography(CTA) compared with conventional cardiac angiography(CA) for the assessment of CTA detection accuracy. Materials and Methods This study induded 18(13 men, 5 worren)patients who underwent both CTA and CA to evaluate coronary artery stenosis of January to July 2006, and two study of during the seven days. We used 64 Volume CT(40mrn detector coverage, 0.625mm thickness, 0.2:1~0.24:1 pitch, 120kvp, 650mA), between the intravenous injection of contrast medium 70-90ml(Iopamidol 370, 4 mL/sec). Scan row data are acquired conticuously images can be reconstructed ten grade R-R interval(5-95%) transfer the 4.2 advantage workstation, and obtained 3 dimensional image. One radiologist and one cardiologist report of the classification of LAD, LCX, RCA with assessment of this artery stenosis of CTA detection accuracy.. Results The 64 volume CTA detected coronary artery stenosis of 79.6%(43 of 54) of all 54 cases conventional coronary angiography, with LAD stenosis of 83.3%(15 of 18), LCX stenosis of 77%(14 of 18), RCA stenosis of 77.7%(14 of 18). Conclusion 64 Volurre Cardiac CT Angiography is good noninvasive technique of very useful inspection to evaluated coronary artery stenosis.
