Physicians who specialise in the diagnosis and treatment of injuries and diseases through the use of medical imaging (radiology) techniques (examinations/tests) include computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET), and ultrasound.

Radiology is a branch of medicine that employs radiation to both diagnose and treat diseases.

The two primary subspecialties within this field are interventional radiology and diagnostic radiology.

The data they offer and the precision with which they are technically executed are not the only factors that affect the outcomes of imaging research.
