- Are imaging studies interpreted by Dr. Johnson covered by Medical Services Plan (MSP) in BC?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Johnson 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.
- Do I need a referral from my doctor to have an imaging study interpreted by Dr. Johnson?
- 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. Johnson provides expert interpretation of these physician-ordered studies.
- 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.
- 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's the difference between an MRI and a CT scan?
- Both are advanced imaging tests, but they use different technologies. CT (Computed Tomography) scans use X-rays and a computer to create detailed cross-sectional images; they are excellent for bone, lungs, abdomen, and detecting acute bleeding. MRI (Magnetic Resonance Imaging) uses a powerful magnetic field and radio waves to create highly detailed images of soft tissues like the brain, spine, joints, and internal organs, without using ionizing radiation. Dr. Johnson or your referring doctor will determine which test is best for your specific medical question.
- Can I speak to Dr. Johnson 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. Johnson (if performing the procedure) would discuss it with you beforehand.
