Radiology departments are specialized areas in hospitals or medical facilities that focus on diagnosing and treating diseases using imaging techniques. These techniques include X-rays, CT scans, MRI scans, and ultrasound. Radiologists, who are medical doctors trained in interpreting these images, play a crucial role in identifying health issues. In addition to diagnosis, radiology departments may also perform interventional procedures, such as biopsies or angioplasty, using imaging guidance. This allows for minimally invasive treatments that can improve patient outcomes. Overall, radiology departments are essential for modern medicine, providing critical information for patient care.
