To evaluate the effect on image quality of a low contrast and radiation dose protocol for cardiac computed tomography (CT) using a low tube voltage, the hybrid-iterative reconstruction algorithm, and(More)
RATIONALE AND OBJECTIVES To compare free-breathing three-dimensional (3D) phase-sensitive inversion recovery (PSIR) with breath-holding two-dimensional (2D) IR sequences to determine which is better(More)
Our aim was to prospectively investigate the contrast agent concentration and the infusion rate to obtain optimal images of the Adamkiewicz artery by 64-row MDCT. Eighty patients were divided into(More)
