Radiology is a medical specialty that involves the use of medical imaging to diagnose and treat diseases within the human body. Radiologists are medical doctors who specialize in the interpretation of images generated by various imaging modalities, including X-rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine.

Radiological imaging techniques are used to create images of the inside of the body, allowing doctors to see internal structures, organs, and tissues without having to perform invasive procedures. Radiology is used to diagnose a wide range of medical conditions, including broken bones, cancer, heart disease, and neurological disorders. It is also used to guide medical procedures such as biopsies and surgeries.

Radiology has advanced significantly in recent years with the development of new imaging technologies and techniques. Radiologists play a critical role in the diagnosis and treatment of many medical conditions, and their expertise is an important part of modern healthcare.
