Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Kravis 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. Kravis?

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. Kravis provides expert interpretation of these physician-ordered studies.

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

A Radiologist (like Dr. Kravis) 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.

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

How will I get the results of my imaging exam?

After your imaging exam is completed, Dr. Kravis (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.

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. Kravis specializes in these image-guided procedures. The focus is on patient safety, minimizing risks, and improving recovery times.
