| 内容記述 | Background: With fast computed tomography (CT), it is possible for the scanning to outpace the contrast medium bolus during aortic CT angiography (CTA). Purpose: To evaluate the effectiveness of a new method for reducing the risk of outpacing in which the scan start timing (ST) and speed can be estimated from the peak enhancement time measured at the femoral artery using a single testbolus injection (femoral artery test injection method [FTI method]). Material and Methods: In 30 cases of aortic CTA, we measured the time to peak enhancement at the femoral artery (TPF) and the ascending aorta (TPA) with test-bolus injection performed twice in each examination. From the resultant linear relationship between TPF and transit time (TTTPF=TPA), we developed a method for determining the ST and TT from TPF. One hundred patients were assigned to two groups: FTI and bolus tracking (BT), each with 50 patients. CT values were measured in main vessels (ascending aorta, descending aorta, femoral artery). The CT values of the vessels and the rate of cases with more than 300 HU (good cases) were compared between the two groups. Results: The enhancement in the FTI method was significantly higher than that of the BT method (average CT values: FTI, 388.352.4; BT, 281.259.1; P<0.001). The rates of good cases for FTI and BT were 86.0% and 46.0%, respectively. Conclusion: The FTI method was very effective in reducing the risk of outpacing of the contrast medium transit in aortic CTA without the need for an additional contrast medium dose. © The Foundation Acta Radiologica 2015. | |||||
