- X-ray Interpretation (Radiography): Expert analysis and reporting of X-ray images for diagnosing conditions related to bones (fractures, arthritis), chest (pneumonia, lung nodules), and abdomen.
- Bone Densitometry (DEXA) Scan Interpretation: Analyzing DEXA scans to measure bone mineral density, assess osteoporosis risk, and monitor treatment effectiveness.
- Computed Tomography (CT) Scan Interpretation: Detailed review and reporting of cross-sectional CT images for evaluating trauma, cancer staging, vascular disease, infections, and other complex conditions throughout the body.
- Fluoroscopy Procedure Interpretation: Interpreting real-time X-ray imaging (fluoroscopy) used during procedures like barium studies (GI tract), hysterosalpingograms, or to guide certain injections.
- Magnetic Resonance Imaging (MRI) Interpretation: Specialized analysis and reporting of MRI scans, providing detailed images of soft tissues, brain, spine, joints, abdomen, and pelvis without using ionizing radiation.
Note: This list provides an overview of common radiology services. Dr. Au interprets a wide range of medical imaging studies and/or performs procedures as indicated by your referring physician. Specific subspecialty services depend on the physician's focus and training.
All medical imaging services are provided in accordance with the standards of practice set by the College of Physicians and Surgeons of Ontario (CPSO).
Dr. Au primarily practices at Shouldice Hospital, located in the Bay Street Corridor (Discovery District) neighborhood of Toronto, near Roy Thomson Hall.

- Are imaging studies interpreted by Dr. Au covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Au are typically covered by Ontario Health Insurance Plan (OHIP) in ON when prescribed by your referring physician and performed at an accredited medical facility. Some advanced or specialized interventional procedures may also be covered. 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. Au?
- 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. Au provides expert interpretation of these physician-ordered studies.
- What does a Radiologist actually do? Do they take the pictures?
- A Radiologist (like Dr. Au) 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.
- I'm concerned about radiation exposure. Are X-rays and CT scans safe?
- Patient safety is our top priority. Radiologists and technologists are trained to use the lowest radiation dose necessary to obtain high-quality diagnostic images (this is known as the ALARA principle - As Low As Reasonably Achievable). While X-rays and CT scans do use ionizing radiation, the amount for most diagnostic exams is carefully controlled and the benefit of an accurate diagnosis generally far outweighs the very small potential risk. If you have specific concerns, please discuss them with your referring doctor or the imaging staff before your exam.
- Is there general preparation needed before an imaging appointment?
- Preparation varies significantly based on the type of imaging test. Some require fasting for several hours, others may need you to drink water for a full bladder, or avoid certain medications. You will receive specific instructions from the clinic or hospital when your appointment is scheduled. It's very important to follow these instructions carefully to ensure the quality of your exam and your safety.
- What is Interventional Radiology?
- Interventional Radiology is a subspecialty of radiology where physicians use medical imaging (like X-ray, CT, ultrasound, MRI) to guide minimally invasive procedures for diagnosis (e.g., biopsies) or treatment of a wide range of conditions in nearly every organ system. These procedures are often alternatives to open surgery. Dr. Au specializes in these image-guided procedures.
