Grand Island Radiology
Grand Island Radiology FAQ
Q: What is a Radiologist and how does this affect my health care?
A: A radiologist is a specialist in interpreting images such as x-rays (radiographs, CT, fluoroscopy), radioactive substances (nuclear medicine), sound waves (ultrasound), or the body’s natural magnetism (MRI). Radiologists are physicians who use images to test patients and treat diseases, even perform image-guided surgery.
Q: What is a PET (Positron Emission Tomography) Scan and what is it used for?
A: A PET scan is a technique that uses a small amount of radioactive glucose (sugar) to examine organs in a patient’s body and help diagnose disease. PET scans show organ structure and function to differentiate between malignant and benign tumors, determine if a disease has moved to another part of the body, and discover abnormalities.
Q: What is the difference in the old style of mammography and Digital Mammography?
A: Mammography has traditionally been recorded on film using an x-ray cassette and viewed using a light box. Digital mammography uses an electronic x-ray detector to convert the image into a digital picture. The magnification, orientation, brightness, and contrast of these images can be altered to allow the radiologist to clearly see areas.
Q: What is a Dexa scan for?
A: A Dexa scan measures bone mineral density. These scans compare results with standard bone density measurements and can help predict a patient’s risk for fractures. Patients who may participate in a Dexa scan include people with Gorhams vanishing bone disease, osteoporosis patients, people with evidence of vertebral abnormalities, long term steroid use, or primary hyperparathyroidism.
Q: What is a CAT (Computed Axial Tomography) scan?
A: A CAT scan sends x-rays through the body which is then absorbed at different levels. This creates a matrix of x-ray beams at different strengths to build a film image. Inside the scanner, an x-ray tube is attached to a rotating frame which takes images or “slices” of the patient each time the tube makes a 360 degree rotation.
Q: How does an MRI work?
A: A patient lies on their back on a table on a horizontal tube which is then slid into the MRI scanner. When inside the scanner, protons inside the body align with the magnetic field direction. A radio frequency electromagnetic field is turned on and the protons change alignment. A signal is created from the alteration in alignment. Damaged tissue can be detected by observing the time to return to equilibrium.
