Fig. 1 —Contrast enhancement in chest. Graph shows comparison of
contrast enhancement in right ventricle, pulmonary trunk, left ventricle, and
descending thoracic aorta between 370 mg I/mL (white) and 300 mg I/mL
(gray) protocols. Bars represent mean CT attenuation ± 1 SD.
Intraindividual mean attenuation values are statistically significantly higher
for 300 mg I/mL protocol than 370 mg I/mL protocol at all anatomic sites with
exception of left ventricle.
