摘要：

Objective: To investigate image quality and radiation dose of single-versus multi-phase acquisition protocol for prospective-triggered sequential dual-source computed tomography (CT) coronary angiography. Materials and methods: A total of 140 patients were randomly assigned to single-or multi-phase group. Image quality and radiation dose were compared. Results: No significant difference was found in image quality between the two groups. Effective dose of single-phase group was 21.6% lower than that of multi-phase group (P<.001). Conclusions: Prospective-triggered sequential dual-source CT coronary angiography using single-phase protocol can reduce radiation dose without sacrifice of image quality in diastole compared with multi-phase protocol.
