Computerized tomography (CT)

Computerized tomography (CT) scans use focused X-rays beams taken at different angles to produce thin cross-sectional image slices of organs, bones, soft tissue and blood vessels within the body. CT images are more detailed and have higher resolution than traditional X-rays and are invaluable tools for diagnosing cancer, neurological disorders, trauma, infectious diseases, cardiovascular disease, musculoskeletal disorders, and gastrointestinal disorders, like appendicitis.

Geisinger’s radiology physicians have passed rigorous exams (are board-certified) and use CT scanners with rapid patient friendly scan times that produce high quality diagnostic images. These scans, along with our radiologists’ diagnoses, provide our patients and physicians with fast, detailed 2-D and 3-D images for optimal care and decision-making.

What you should know about computerized tomography 

  • A CT scan is a fast, noninvasive, painless test. It produces accurate results for quick diagnoses. In emergency situations, a CT scan can quickly reveal internal trauma and bleeding.
  • CT scans can be used to diagnose different types of cancer. From the images, physicians are able to identify the presence of and location of tumors, measure their size and determine their impact on surrounding tissue.
  • The acquired CT scan image data are frequently used to produce 3-D virtual images, and now state-of-the art 3-D solid prints, for pre-surgical planning purposes.

Conditions treated with CT scans

CT scans are used to deliver fast, accurate and highly detailed images to diagnose and treat a range of conditions, including:

  • Cancer
  • Stroke, and other neurological disorders
  • Internal injuries and bleeding from trauma
  • Cardiovascular disease
  • Musculoskeletal disorders
  • Infectious disease
