- Are imaging studies interpreted by Dr. Guest covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Guest 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. Guest?
- 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. Guest provides expert interpretation of these physician-ordered studies.
- 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'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. Guest or your referring doctor will determine which test is best for your specific medical question.
