Good SamaritanServices and Clinical CentersDiagnostic Imaging

CT Scan

A CT scan is a radiographic procedure that includes very thin, finely detailed, high resolution x-ray images. The scanner is shaped like a large doughnut and the exam table slides back and forth through the scanner as we acquire the images. You may be asked to hold your breath as we acquire the images. An intercom system will allow the technologist to hear you and speak with you throughout the procedure.

In all instances it will be important that you lie very still while we perform your exam to ensure diagnostic images and for your safety.

 **If you are pregnant, or believe that you may be pregnant, please alert the technologist prior to your CT scan.**

Approximate Exam Time:

  • Abdomen/Pelvis CT scan - Typically 10 to 15 minutes
  • Chest scan - Typically 10 to 15 minutes
  • Head/Brain scan - Typically 5 to 10 minutes
  • Spine/Extremity - Typically 5 to 10 minutes
  • CTA angiograms - Typically 10 to 20 minutes

Good Samaritan Medical Center has two multidetector CT scanners with the latest technology. We have a state-of-the-art 64-slice CT scanner, which are interpreted by both a radiologist and cardiologist.

CT exam image data is recorded and manipulated by the technologists and radiologists into various two- and three-dimensional images for interpretation. These images are then stored electronically in our Picture, Archive and Communication System (PACS) for easy access by authorized personnel.

CT Scan Preparations

When your examination is ordered/scheduled, the scheduling staff will inform you about any exam preparations.

  • In most instances you will not be allowed to eat or drink for two to three hours prior to the exam.
  • When clinically indicated, your exam may include an injection of IV contrast material. Most patients get a warm feeling throughout their body as the contrast material is injected.
  • It is important for us to know if you have any allergies to shellfish, iodine or X-ray dye.
  • Most abdomen and pelvic CT scans require an oral contrast that you must drink for two to three hours prior to the exam.
  • Your physician will receive your exam results typically within five days. If there is any finding on your exam that requires immediate attention, the radiologist will contact your doctor directly.
