Dr. Michel Pierre Dufresne

• Bone Densitometry (DEXA) Scan Interpretation: Analyzing DEXA scans to measure bone mineral density, assess osteoporosis risk, and monitor treatment effectiveness.
• Ultrasound Interpretation (Sonography): Evaluation and reporting of diagnostic ultrasound images for assessing organs (e.g., liver, kidneys, thyroid, reproductive organs), blood flow, pregnancies, and musculoskeletal conditions.
• 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.
• Mammography and Breast Imaging Interpretation: Expert review and reporting of mammograms (including tomosynthesis/3D mammography) and breast ultrasound for cancer screening, diagnosis, and follow-up.
• 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.

Are imaging studies interpreted by Dr. Dufresne covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Dufresne are typically covered by Régie de l'assurance maladie du Québec (RAMQ) in QC 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 Régie de l'assurance maladie du Québec (RAMQ) or the imaging clinic/hospital.

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

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

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.

How will I get the results of my imaging exam?

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

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. Dufresne see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.
