- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Guérin 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. Guérin?
- 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. Guérin provides expert interpretation of these physician-ordered studies.
- How will I get the results of my imaging exam?
- After your imaging exam is completed, Dr. Guérin (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.
- 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.
- 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. Guérin specializes in these image-guided procedures. She performs a variety of minimally invasive interventions that can diagnose and treat many medical conditions with reduced recovery times and less risk compared to traditional surgery.
