A radiologist is a physician who specialises in obtaining and interpreting medical images, making him or her an imaging expert. Medical images are obtained by using x-rays (radiographs, CT, fluoroscopy), or radioactive substances (nuclear medicine), others by means of sound waves (ultrasound) or the body's natural magnetism (MRI).
Radiologists assist or advise other doctors and specialists when diagnosing and treating patients using medical imaging.
There are approximately 70 radiologists in Western Australia all of who are based in the metropolitan area. Less than 20% of the practitioners are women.
