Computed Tomography (CT) is a non-invasive medical procedure using specialized x-ray equipment to produce multiple cross-sectional images (“slices”) of the body. Multiple images are taken of an area of the body at various angles. CT scans help physicians evaluate and visualize internal organs, soft tissues, and bones with greater detail than traditional x-rays. It is often utilized to help diagnose diseases, trauma, or abnormalities, monitor treatment, visualize tumors, foreign objects, infection, fluid collection, and more. CT scans may be used on every region of the body and provide greater clarity and detail than traditional x-ray images and digital x-rays.
Before an exam, patients may be asked to remove all materials containing any metal such as jewelry, undergarments, belts, dentures, glasses, piercings, and hearing aids. CT may or may not include an injection of contrast material, based on the discretion of physicians. If a CT with contrast is to be done, patients may be asked to obtain a blood test to determine kidney function prior to the exam. Patient taking some diabetic medications may also be asked to discontinue for 24 to 48 hours prior to the exam. You should disclose any allergies to iodine or prior reactions to contrast media to the technician and/or radiologist. Some CT scans may also require fasting hours before the exam. Please consult with technicians and/or radiologists regarding medications, blood work, and fasting before the exam.
** Please consult with your physician and/or radiologist for detailed instructions or any concerns regarding on how to prepare for your CT, current and/or past allergies, and other recent illnesses or medical conditions such as kidney diseases before the examination. It is important to inform physicians and x-ray technicians if a woman believe she is or may be pregnant. If you have a fear of enclosed spaces (claustrophobia) or anxiety, please consult with the physician on obtaining a mild sedative before the scheduled exam.
