CT Scan

At St. Joseph Regional Medical Center, we use state-of-the-art computed tomography (CT) software with the latest of reconstruction techniques to analyze images. This software provides 3-D reconstruction of images, transmitted to board-certified radiology specialists for diagnosis.

A CT scan uses x-ray images with the aid of a computer to generate cross-sectional and, in some cases, 3-D views of the body. Think of the CT images as viewing a loaf of bread. With all the slices together, you can see the entire loaf. However, if you want to look at each slice, you have the ability to see what is inside the loaf. When all the slices are added together again, you have that 3-D view.

CT scans are performed to analyze the internal structures of the body. This includes the head, where traumatic injuries such as blood clots, skull fractures, tumors and infections can be identified. In the spine, the bony structure of the vertebral column can be defined, as can the disks and spinal cord. In the abdomen, CT scanning helps to identify anatomy such as the liver, gallbladder, pancreas, spleen, aorta, kidneys, uterus and ovaries. CT scans are used to assess the presence or absence of tumors, infection, abnormal anatomy or changes of the body caused by trauma.

Occasionally, contrast may be given to further enhance the scan and various structural relationships. This is usually painless and may involve drinking a solution before your CT scan. You may also require intravenous (IV) contrast for your exam. In this case you will be given an IV before your exam for the contrast to be administered.

Most procedures take 5 to 15 minutes and are relatively painless. Your technologist will make you as comfortable as possible.
