Body weight-tailored contrast material injection protocol for 64-detector row computed tomography coronary angiography.

Purpose: The aim of this study was to assess the body weight-tailored contrast material injection protocol for 64-detector computed tomography (CT) to maintain optimal coronary CT attenuation.

Materials And Methods: A total of 60 patients who underwent CT coronary angiography were assigned to one of three groups: protocol A, total of 0.7 ml kg(-1) with 300 mg I/ml iodine concentration; protocol B, total of 0.
