Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to CT images.

What are the types of error in radiology?

Two broad categories of radiologic error have been identified: perceptual errors and cognitive (interpretive) errors. Perceptual errors are far more common, accounting for 60%–80% of radiologists' errors (4,5,8,10,11). Perceptual errors occur during the initial detection phase of image interpretation.
