64 - Detector CT Scan

Low Dose CT

G.E. Featherlight Technology - Dose Optimization

  • Reduces radiation dosage on CT exams by up to 40% by automatically adjusting to the patients actual body mass without impacting image quality.
  • 3D dose modulation accounts for the body in all three dimensions, personalizing each exam

CT scan is an advanced system producing cross-sectional images of the body much like the slicing of a loaf of bread. It is a highly sensitive method to accurately view the internal anatomy and detect extremely small lesions. Utilizing high speed computers, the CT obtains 360 degrees of X-ray information. The information is processed into single slice images for display on a computer monitor and can be reproduced on film or high quality photographic paper.

Our GE 64 detector helical CT significantly shortens examination times and reduces the volume of intravenous non-ionic contrast material administered while providing exceptional resolution. Helical scanning produces, during a single breath hold, multiple contiguous slices so that extremely small lesions are not obscured. State-of-the-art 64 Detector technology provides the thinnest available motion-free slices necessary for CT angiography (direct mapping and analysis of the arteries of the body, such as aorta, carotids, coronaries, kidneys and extremities) and advanced 3D reconstruction of images. These features enhance diagnostic sensitivity, earlier detection, and consistent follow-up of pathology while allowing improved patient comfort.

At least 16-detector CT is required for adequate CT enterography., the CT study of the small bowel, for the investigation of inflammatory bowel disease and abnormal growths within the bowel. The fluid-filled small bowel is depicted motion-free in various cross-sectional planes.

During Your CT Scan

During the scan, the patient will be asked to rest motionless on a padded table for 5 to 15 minutes depending on the area of the body to be scanned. The table moves every few seconds as the images are obtained. The patient will hear faint humming and clicking sounds. Once the images are taken, a radiologist will review the images to ensure all of the area has been covered. Sometimes because of breathing or motion inside the body additional images are needed. Additional images do not mean there is a problem.

Depending on the part of the body being scanned different contrast materials are used. Very often contrast is given through the vein (intravenous). The contrast we use is non-ionic iodinated contrast. If the patient has an iodine allergy or if they have had a reaction to contrast in the past you should notify the office when you are making the appointment and also at the time of the scan so we may take additional precautions to avoid a problem.

Oral contrast is usually given for CT scans that include the abdomen and pelvis. For CT examinations that include the pelvis, the patient will be asked to arrive an hour before the actual scan time to drink. For a CT scan of only the abdomen the patient will be scheduled to arrive a half-hour before scanning. The early arrival is necessary to allow adequate filling of the intestines, which helps in the proper interpretation of the study. If the patient is breast-feeding or pregnant, please let the scheduler know before booking the examination.
