- Fluoroscopy Procedure Interpretation: Interpreting real-time X-ray imaging (fluoroscopy) used during procedures like barium studies (GI tract), hysterosalpingograms, or to guide certain injections.
- X-ray Interpretation (Radiography): Expert analysis and reporting of X-ray images for diagnosing conditions related to bones (fractures, arthritis), chest (pneumonia, lung nodules), and abdomen.
- Magnetic Resonance Imaging (MRI) Interpretation: Specialized analysis and reporting of MRI scans, providing detailed images of soft tissues, brain, spine, joints, abdomen, and pelvis without using ionizing radiation.
- Bone Densitometry (DEXA) Scan Interpretation: Analyzing DEXA scans to measure bone mineral density, assess osteoporosis risk, and monitor treatment effectiveness.
- Mammography and Breast Imaging Interpretation: Expert review and reporting of mammograms (including tomosynthesis/3D mammography) and breast ultrasound for cancer screening, diagnosis, and follow-up.
Note: This list provides an overview of common radiology services. Dr. Sloan interprets a wide range of medical imaging studies and/or performs procedures as indicated by your referring physician. Specific subspecialty services depend on the physician's focus and training.

- Are imaging studies interpreted by Dr. Sloan covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Sloan 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. Sloan?
- 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. Sloan provides expert interpretation of these physician-ordered 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. Sloan see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.
- 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. Sloan specializes in these image-guided procedures.
- 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.
