How to replace CT scans with MRI scans to reduce cancer risks

New studies by radiologists have shown that MRI can be just as accurate as CT scans at helping radiologists diagnose pathologies such as cancer, cysts and kidney stones -- while carrying less risk, especially for pregnant women. The magnetic waves and radio frequency energy used in MRI are a safer alternative to the potentially carcinogenic X-rays of CT scans, especially during gestation. CT scans are still much faster, but medical physicists are working on developing faster MRI machines.
