- Are imaging studies interpreted by Dr. Lynch covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Lynch are typically covered by Ontario Health Insurance Plan (OHIP) in ON 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 Ontario Health Insurance Plan (OHIP) or the imaging clinic/hospital.
- Do I need a referral from my doctor to have an imaging study interpreted by Dr. Lynch?
- 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. Lynch provides expert interpretation of these physician-ordered studies.
- Can I speak to Dr. Lynch 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. Lynch (if performing the procedure) would discuss it with you beforehand.
- 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. Lynch see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.
