Radiologists are medical professionals who specialize in interpreting and diagnosing images created by various imaging technologies, such as X-rays, MRIs, CT scans, ultrasounds, and PET scans. They play a crucial role in helping physicians accurately diagnose and treat diseases and injuries. Radiologists use their expertise to identify abnormalities, such as tumors or fractures, within the body and provide detailed reports to referring physicians. They often work closely with other healthcare providers to determine the most appropriate course of treatment for patients. Additionally, radiologists may also perform certain minimally invasive procedures, such as biopsies or drain placements, using imaging guidance.
