Radiologists are medical doctors who specialize in diagnosing and treating diseases and injuries using medical imaging techniques such as X-rays, CT scans, MRIs, and ultrasounds. They play a crucial role in patient care by interpreting images and providing reports that guide treatment decisions. In addition to diagnosis, some radiologists also perform interventional procedures, which involve using imaging guidance to treat conditions. Their expertise is essential in various medical fields, making them vital members of healthcare teams, ensuring accurate diagnoses and effective treatment plans for patients.
