- Do I need a referral from my doctor to have an imaging study interpreted by Dr. Barfett?
- 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. Barfett provides expert interpretation of these physician-ordered studies.
- 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. Barfett specializes in these image-guided procedures.
- 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. Barfett see abnormalities that might otherwise be hidden. Not all scans require contrast; it's used when it can provide important additional diagnostic information.
