Using MRI as a screening test alongside PSA density allowed detection of cancers that would have been missed by the blood test alone, according to new research out of London.
A study reveals that Medicare beneficiaries in high-income communities are 5.7 times more likely to receive CT colonography for colorectal cancer screening, with Medicare's non-coverage of CT colonography possibly contributing to these disparities.
Assistance from an artificial intelligence (AI) algorithm with high diagnostic accuracy improved radiologist performance in detecting lung cancers on chest X-rays and increased human acceptance of AI suggestions.
