Are imaging studies interpreted by Dr. Trepanier covered by Medical Services Plan (MSP) in BC?

Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Trepanier are typically covered by Medical Services Plan (MSP) in BC 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 Medical Services Plan (MSP) or the imaging clinic/hospital.

Do I need a referral from my doctor to have an imaging study interpreted by Dr. Trepanier?

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. Trepanier 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.

Why might I need an injection of 'contrast' or 'dye' for my scan?

Contrast material (often called 'dye', though it's usually clear) is a special substance that can be injected intravenously (or sometimes taken orally or rectally) to help certain organs, blood vessels, or tissues stand out more clearly on imaging exams like CT or MRI. It can help Dr. Trepanier see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.

What's the difference between an MRI and a CT scan?

Both are advanced imaging tests, but they use different technologies. CT (Computed Tomography) scans use X-rays and a computer to create detailed cross-sectional images; they are excellent for bone, lungs, abdomen, and detecting acute bleeding. MRI (Magnetic Resonance Imaging) uses a powerful magnetic field and radio waves to create highly detailed images of soft tissues like the brain, spine, joints, and internal organs, without using ionizing radiation. Dr. Trepanier or your referring doctor will determine which test is best for your specific medical question.

How will I get the results of my imaging exam?

After your imaging exam is completed, Dr. Trepanier (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.
