CT (Computed Tomography)

What is a CT Scan?

CT (Computed Tomography) scans use rotating x-ray beams to
acquire cross- sectional images of the body. The images are taken from
different angles and are used to create 3-dimensional (3-D) views of
tissues and organs. A dye may be injected into a vein or swallowed to
help the tissues and organs show up more clearly.

A CT scan provides a high resolution image of the body and is currently
the preferred method for diagnosing many diseases and injuries. CT
scans can also be used for pre-operative planning, to diagnose cysts,
tumors, blood diseases, blood clots, hemorrhages, infections and to
monitor recovery from illness.

Our CT scanners provide excellent exam quality with fast acquisition
speeds while delivering very low doses of radiation.
Our computer-assisted reading tools also enable early detection,
fast evaluation and precise follow-up of disease with all
information available at the scanner before the patient is off the

Preparing for your CT Scan

Many types of CT scans do not require patient preparation, but some require either an oral dose or an IV injection of contrast material. Contrast provides improved definition of the internal organs and increases the sensitivity of the scan in terms of detecting some diseases. Oral contrast is also frequently used during abdominal and pelvic CT imaging.

Abdominal and/or Pelvic CT

No food or drink after midnight, except water to take medications. You may be asked to consume one bottle of oral contrast the night prior to your exam and a second bottle of contrast one hour before your appointment.

You may be asked to remove some or all of your clothing and to change into a scrub top, scrub pants or gown during the exam. You may also be asked to remove jewelry, eye glasses, hearing aids, removable dental
work and any metal objects or clothing that might interfere with the CT images. Women should always inform the technologist if there is any possibility that they are pregnant.
