CT Scan

Emerson Hospital uses the latest high speed, multi slice CT (computerized tomography) technology to take images that are unsurpassed in resolution and clinical detail. Our state-of-the-art imaging system enables quick, accurate diagnosis for head and spine injuries, lung and liver disease, cancer, tumors, cardiovascular disease, bone/joint and more.

CT Scan services are available at our Main Campus and the Westford Health Center. Both CT locations are accredited and have dose modulation to minimize radiation exposure.

  • Preparing for a CT Scan

    • If you chose not to change into the gown provided, you should wear comfortable, loose-fitting clothing to your exam. Underwire bras or pants with metal should not be worn.
    • Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and removable dental work.
    • You may be asked not to eat or drink anything for three hours beforehand, especially if a contrast material is used in your exam. You should inform your physician of any medications you are taking and if you have any allergies. If you have a known allergy to contrast material, or "dye," please inform your doctor so he or she can prescribe medications to reduce the risk of an allergic reaction.
    • Also inform your doctor of any recent illnesses or other medical conditions, and if you have a history of heart disease, asthma, diabetes, kidney disease or thyroid problems. Any of these conditions may increase the risk of an unusual adverse effect.
    • Women should always inform their physician and the CT technologist if there is any possibility that they are pregnant. Many imaging tests are not performed during pregnancy so as not to expose the fetus to radiation. If a CT scan is necessary, precautions will be taken to minimize radiation exposure to the baby.
  • What to Expect During the Procedure

    • Most CT exams are painless, fast and easy. Your technologist will instruct you to lie on the examination table that moves through the CT scanner. The test will be explained to you and you will have an opportunity to ask questions prior starting the exam. The technologist cannot stand in the room during the test but can see and hear you at all times.
    • Some CT scans require an intravenous injection to enhance your vessels. Some Abdominal scans require you to also drink an oral contrast material to better visual the intestines. The contrast assists the radiologists and doctors in detecting tumors, abscesses or vascular abnormalities.
    • If you are over 60 or diabetic, you will be asked to have a blood test within 30 days of your exam.
    • The CT scanning is usually completed within 15-30 minutes.
  • After the Procedure

    • After a CT exam, you may return to normal activities.
    • If an IV contrast material was given, we encourage you to drink extra water after the procedure.
  • About CT Scanning

    CT scanning — sometimes called CAT scanning — is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

    CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor or printed.

    CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams.
