New study aims to end sex bias in CT scans by tailoring contrast doses

This study tests if giving CT contrast dye based on a person's blood volume, instead of just weight, can reduce differences in image quality between women and men. Researchers found women often get stronger contrast than men of the same size, likely due to lower blood volume. The trial will compare standard weight-based dosing to blood-volume-based dosing in 400 adults needing a CT scan.
