Radiology is a branch of medicine that uses imaging techniques, such as X-rays and MRI scans, to diagnose and treat various medical conditions. It involves using radiation, usually in the form of electromagnetic waves or particles, to create images of internal body structures, including bones, organs, and tissues. The goal is to identify any abnormalities that may be present, such as tumors, fractures, or other injuries. Radiology can also be used for therapeutic purposes, such as radiation therapy for cancer treatment.
