This data was created for evaluating the image quality of low voltage chest CT using low-concentration-iodine contrast media (LCCM). From December 9 to December 19 2019, three different protocols were used for 263 patients undergoing chest CT with enhancement examinations. Chest CT with enhancement was done using routine (300 mgI/ml contrast media with 100 kVp) protocol (group 1), LCCM (240 mgI/ml contrast media)–100 kVp protocol (group 2), and LCCM–80 kVp protocol (group 3) in 91, 97, and 75 patients, respectively. The overall diagnostic acceptability, anatomical depiction, noise, and contrast-related artifacts were assessed. Additionally, the mean attenuation, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and figure of merit (FOM) in the aorta and the main pulmonary trunk were measured.
