CT SCAN

CT or Computed Tomography – is a painless test that combines x-rays and computers to produce high-resolution 2D and 3D images of the inside of the body. The result is a detailed picture that may show problems with soft tissues, internal organs and bones in greater detail than traditional x-rays. CT uses a small amount of radiation but the benefits of this test far outweigh any risk.

Technology

Our GE VCT 64 slice, Siemens Sensation 64 slice, Siemens Emotion 16 slice are state of the art CT scanners that will produce high quality images that will result in a more accurate diagnosis.

Before the Test

  • You should wear comfortable, loose-fitting clothing for your exam. You may be asked to wear a gown during the examination.
  • 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. Women will be asked to remove bras containing metal underwire. You may be asked to remove any piercings, if possible.
  • Report any allergies to the radiology technologist, especially those to iodine contrast (x-ray dye).
  • Women should always inform the x-ray 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 IV contrast will be used, patients over the age of 50 years old require a blood test within the past 30 days to measure their Creatinine level.
  • If IV contrast will be used, diabetic patients taking Glucophage, Glucovance or any other medication containing metformin must discontinue use of this medication for the day of and 48 hours after the examination.
  • If oral contrast is required, do not eat solid foods 4 hours prior to exam. Clear liquids and medications are allowed up to 2 hours before exam. Patients need to drink a barium contrast (a liquid that shows the intestines) two hours prior to the exam. Please pick up before your exam.

During the Test

  • If an intravenous contrast material is used, you will feel a pin prick when the needle is inserted into your vein. You will likely have a warm, flushed sensation during the injection of the contrast material and a metallic taste in your mouth that lasts for at most a minute or two. You may experience a sensation like you have to urinate; however, this is actually a contrast effect and subsides quickly.
  • The technologist begins by positioning you on the CT examination table, usually lying flat on your back. Straps and pillows may be used to help you maintain the correct position and to help you remain still during the exam.
  • Next, the table will move quickly through the scanner to determine the correct starting position for the scans. Then, the table will move slowly through the machine as the actual CT scanning is performed.
  • You may be asked to hold your breath during the scanning. Any motion, whether breathing or body movements, can lead to loss of image quality. This can resemble the blurring seen on a photograph taken of a moving object.

After the Test

  • After a CT exam, the intravenous line used to inject the contrast material will be removed by the technologist.
  • There are no restrictions after a CT scan. You should be able to resume your normal activities immediately.
  • A report from today’s exam will be sent to your doctor within 24 hours.
