- Are imaging studies interpreted by Dr. Leung covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Leung are typically covered by Ontario Health Insurance Plan (OHIP) in ON when prescribed by your referring physician and performed at an accredited medical facility.

It's always best to confirm specific coverage details with Ontario Health Insurance Plan (OHIP) or the imaging clinic/hospital.
- Do I need a referral from my doctor to have an imaging study interpreted by Dr. Leung?
- Yes, almost all diagnostic imaging tests (like X-rays, CT, MRI, ultrasounds) and interventional radiology procedures require a formal request or requisition from your family doctor, specialist, or other authorized healthcare provider. Dr. Leung provides expert interpretation of these physician-ordered studies.
- Can I speak to Dr. Leung directly about my images?
- Typically, the Radiologist's detailed report is sent to your referring physician, who is best positioned to discuss the results with you in the context of your overall health and other test findings. While direct consultation with the interpreting Radiologist is uncommon for routine diagnostic imaging, for Interventional Radiology procedures, Dr. Leung (if performing the procedure) would discuss it with you beforehand.
- How long will my imaging test take?
- The duration depends on the type of scan. A simple X-ray might take only a few minutes. Ultrasounds can range from 15 to 45 minutes. CT scans are usually quick once you're positioned (actual scan time is often under a minute), but total appointment time can be longer. MRI scans are typically the longest, often 30 to 60 minutes or more per body part being imaged.
- What does a Radiologist actually do? Do they take the pictures?
- A Radiologist (like Dr. Leung) is a medical doctor who has completed extensive specialty training in interpreting all types of medical images (X-rays, CT, MRI, ultrasound, nuclear medicine, etc.) to diagnose diseases and injuries. They provide a written report of their findings to your doctor. While skilled technologists operate the imaging equipment to take the pictures, the Radiologist is the expert physician who analyzes these images to provide a diagnosis. Some Radiologists (Interventional Radiologists) also perform image-guided minimally invasive procedures.
