Radiology is a medical specialty focused on using medical imaging techniques to diagnose and treat diseases and injuries. Radiologists interpret imaging studies such as X-rays, CT scans, MRI scans, ultrasound, and nuclear medicine scans to help diagnose conditions ranging from fractures and tumors to infections and internal injuries. They work closely with other healthcare professionals to provide accurate diagnoses and guide treatment plans. Interventional radiologists also perform minimally invasive procedures using imaging guidance, such as angioplasty, biopsies, and tumor ablations. Radiology plays a critical role in modern medicine by providing essential diagnostic information and contributing to patient care across various medical specialties.
