PDFAbstract
Objective To explore the value of low-dose scanning technology and advanced iterative reconstruction technology using the 64 multidetector CT (64- MDCT) for achieving low-dose pelvic examination. Methods 86 patients were randomly assigned to the regular dose group and low-dose group to receive 64-MDCT pelvic examination,low-dose scanning technology and advanced iterative reconstruction technology were applied in low-dose group,image quality and exposure dose were compared. Results The exposure dose of low- dose group is lower than the regular dose group (t=82.34,P＜0.05), there is no difference in image quality of the two groups (t=2.17,2.58,P＞0.05). Conclusion It is feasible to use the 64-MDCT examine patients in a low-dose way, and low-dose scanning technique can ensure the diagnostic quality and reduce the exposure dose.
