- Are imaging studies interpreted by Dr. Janzen covered by Medical Services Plan (MSP) in BC?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Janzen are typically covered by Medical Services Plan (MSP) in BC 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 Medical Services Plan (MSP) or the imaging clinic/hospital.
Coverage depends on the specific procedure and your individual circumstances. It is advisable to check with your healthcare provider or MSP for confirmation prior to scheduling imaging services.
- Do I need a referral from my doctor to have an imaging study interpreted by Dr. Janzen?
- 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. Janzen provides expert interpretation of these physician-ordered studies.
You should obtain a referral from your healthcare provider to ensure proper scheduling and to facilitate accurate interpretation and reporting.
- 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. Janzen see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.
- 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.
- How will I get the results of my imaging exam?
- After your imaging exam is completed, Dr. Janzen (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.
Timely communication with your referring healthcare provider ensures you receive the results and next steps promptly.
- 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.
