- Are imaging studies interpreted by Dr. Cheng covered by Alberta Health Care Insurance Plan (AHCIP) in AB?
- Medically necessary diagnostic imaging studies interpreted by a Radiologist like Dr. Cheng are typically covered by Alberta Health Care Insurance Plan (AHCIP) in AB 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 Alberta Health Care Insurance Plan (AHCIP) or the imaging clinic/hospital.
- Do I need a referral from my doctor to have an imaging study interpreted by Dr. Cheng?
- 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. Cheng 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.
- 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. Cheng see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.
- 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. Cheng or your referring doctor will determine which test is best for your specific medical question.
- 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.
