Radiology is a medical specialty that uses imaging techniques to diagnose and treat diseases. Common imaging methods include X-rays, CT scans, MRI, and ultrasound. These technologies allow healthcare professionals to visualize the internal structures of the body, aiding in accurate diagnosis and treatment planning. In addition to diagnostics, radiology also encompasses interventional procedures where imaging guidance is used to perform minimally invasive treatments. This can include procedures like angioplasty or biopsies, which can significantly reduce recovery time and improve patient outcomes.
