CT scanning of Chest

What is CT Scanning of the chest?

CT scanning—sometimes called Computed Tomography or CAT scanning—is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor, printed or transferred to a CD.

CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams

Why should I do it?

CT scanning of Chest is typically used to detect:

  • further examine abnormalities found on conventional chest x-rays.
  • help diagnose the cause of clinical signs or symptoms of disease of the chest, such as cough, shortness of breath, chest pain, or fever.
  • detect and evaluate the extent of tumors that arise in the chest, or tumors that have spread there from other parts of the body.
  • assess whether tumors are responding to treatment.
  • help plan radiation therapy.
  • evaluate injury to the chest, including the blood vessels, lungs, ribs and spine.
  • further evaluate abnormalities of the chest found on fetal ultrasound examinations.

Any preparations needed?

  • You should wear comfortable, loose-fitting clothing to your exam.
  • Metal objects, including jewelry, eyeglasses, dentures and hairpins should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and removable dental work. Women will be asked to remove bras containing metal underwire. You may be asked to remove any piercings, if possible.
  • You should inform the technologist if you have a pacemaker.
  • You may be asked not to eat or drink anything for a few hours beforehand, especially if a contrast material will be used in your exam.
  • You should inform your physician of all medications you are taking and if you have any allergies.
  • Inform your doctor of any recent illnesses or other medical conditions and whether you have a history of heart disease, asthma, diabetes, kidney disease or thyroid problems.
  • Women should always inform their physician and the CT technologist if there is any possibility that they may be pregnant.
