Radiology is the medical specialty of imaging: X-ray, ultrasound, CT, MRI and bone density scanning such as DEXA. Imaging confirms diagnoses, monitors conditions and guides procedures.
A doctor issues a radiology referral and the scan is performed at a local imaging practice, with many examinations Medicare rebateable when clinically indicated. Referrals issued through a telehealth consultation work exactly like paper ones from a physical clinic, and results are sent back to the referring doctor for review with the patient.
