Radiology is the medical field that uses imaging techniques to diagnose and treat diseases. Radiologists utilize X-rays, CT scans, MRIs, and ultrasounds to detect fractures, tumors, infections, and internal injuries. Interventional radiology allows doctors to perform minimally invasive procedures, such as treating blocked arteries without surgery. This specialty is essential in cancer detection, pregnancy monitoring, and emergency medicine. Radiology has revolutionized healthcare by providing detailed images that help doctors make accurate diagnoses and plan effective treatments, ensuring better patient outcomes.
