Are imaging studies interpreted by Dr. Stroz covered by Ontario Health Insurance Plan (OHIP) in ON?

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

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

I'm concerned about radiation exposure. Are X-rays and CT scans safe?

Patient safety is our top priority. Radiologists and technologists are trained to use the lowest radiation dose necessary to obtain high-quality diagnostic images (this is known as the ALARA principle - As Low As Reasonably Achievable). While X-rays and CT scans do use ionizing radiation, the amount for most diagnostic exams is carefully controlled and the benefit of an accurate diagnosis generally far outweighs the very small potential risk. If you have specific concerns, please discuss them with your referring doctor or the imaging staff before your exam.

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

A Radiologist (like Dr. Stroz) 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.

How long will my imaging test take?

The duration depends on the type of scan. A simple X-ray might take only a few minutes. Ultrasounds can range from 15 to 45 minutes. CT scans are usually quick once you're positioned (actual scan time is often under a minute), but total appointment time can be longer. MRI scans are typically the longest, often 30 to 60 minutes or more per body part being imaged.

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. Stroz specializes in these image-guided procedures. She performs a variety of minimally invasive treatments guided by imaging to diagnose and manage complex medical conditions, aiming to reduce patient recovery times and procedural risks.
