Are imaging studies interpreted by Dr. Desrosiers covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?
Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Desrosiers 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. Desrosiers?
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. Desrosiers provides expert interpretation of these physician-ordered studies.
What does a Radiologist actually do? Do they take the pictures?
A Radiologist (like Dr. Desrosiers) 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.
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. Desrosiers specializes in these image-guided procedures.
Can I speak to Dr. Desrosiers 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. Desrosiers (if performing the procedure) would discuss it with you beforehand.
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. Desrosiers or your referring doctor will determine which test is best for your specific medical question.
