摘要

We compare the performance of low tube voltage with the hybrid iterative reconstruction (iDose) with standard and low tube voltage with the filtered backprojection (FBP) using phantoms at computed tomographic coronary angiography. In computed tomographic coronary angiography, application of the combined low tube voltage with iDose resulted in significant image quality improvements compared to the low tube voltage with FBP. Image quality was the same or better despite a reduction in the radiation dose by 76% compared with standard tube voltage with FBP.

Summary: This study evaluated the diagnostic ability of low tube voltage CTV with IR for deep vein thrombosis (DVT) compared to ultrasonography (US). The study found that above the knee, both low tube voltage CTV with IR and conventional CTV had comparable diagnostic ability for DVT, with reduced radiation dose. However, eccentric DVT measured by CTV tended to be a false positive, especially in the calf muscular vein.
