영문 초록

In high version MDCT, is applying effective mAs that is different from constant mAs that is existent one time rotation mAs concept. By concept that consider pitch effect in dose that apply effective mAs in CT equipment and with image quality pitch to do increase to compensate image Quality’s decrease mA automatically increase. Even if increase pitch, whole dose by equal dose scan progress do. Therefore, in effective mAs pitch’s increase patient exposure dose effect that shorten scan duration without doing decrease appear. By Pitch’s increase, image quality decrease in case problem is or applies to pediatric patient that there are much actions in breath because fast scan consists by equal dose if is not done diagnosis value big.
