Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Nash 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. Yes, these services are generally covered when appropriately authorized and performed within the provincial healthcare system.

Do I need a referral from my doctor to have an imaging study interpreted by Dr. Nash?

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. Nash provides expert interpretation of these physician-ordered studies. Having a proper referral ensures appropriate and timely assessment of your imaging studies.

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. Nash see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.

Can I speak to Dr. Nash 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. Nash (if performing the procedure) would discuss it with you beforehand.

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 does a Radiologist actually do? Do they take the pictures?

A Radiologist (like Dr. Nash) 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.
