Radiology is a Medical Speciality that employs the use of imaging to both diagnose and treat diseases visualized within the human body. Radiologists utilize an array of imaging technologies (X - Ray Radiography, Ultrasound (USG), Computed Tomography (CT), Nuclear Medicine, Positron Emission Tomography (PET), Magnetic Resonance Imaging (MRI)) to diagnose or treat diseases. Interventional Radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies.

A Radiologist commonly treats the following conditions:

Fractures; Headache; Gastrointestinal Disorders; Respiratory Disorders; Cardiovascular Disorders; Urinary Tract Disorders; Gynaecological Disorders; Skin Disorders; Musculoskeletal Disorders; Endocrinological Disorders; Urinary Disorders
