Are imaging studies interpreted by Dr. Williams covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Williams 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. Williams?

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. Williams provides expert interpretation of these physician-ordered studies.

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.

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.

How will I get the results of my imaging exam?

After your imaging exam is completed, Dr. Williams (or a colleague Radiologist) will carefully review the images and prepare a detailed report. This report is sent directly to the physician who ordered your test (your referring doctor). Your referring doctor will then discuss the results with you, typically at a follow-up appointment, and explain what they mean in the context of your overall health. Please allow a few business days for the report to reach your doctor.
