When a doctor diagnoses your illness or injury, they often need an radiological examination to support the diagnosis.
Such examinations may include traditional X-ray examinations, ultrasound examinations, mammography, bone density measurements, dental x-ray, computed tomography, magnetic resonance examinations and interventional radiological procedures.
A doctor's referral is required for a radiological examination or procedure. Your doctor in charge of your treatment will determine which examination or procedure is necessary for you at any given time.
