- Are imaging studies interpreted by Dr. Billiard covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Billiard 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. Billiard?
- 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. Billiard provides expert interpretation of these physician-ordered studies.
- What does a Radiologist actually do? Do they take the pictures?
- A Radiologist (like Dr. Billiard) 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.
- 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. Billiard see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.
