The process of taking a lung CT begins by taking many different X-ray views at various different angles, which are then combined with the use of computer processing to create cross-sectional images of the organ inside of your body, including tissues inside.
Ordinary X-ray testing does not show clear images of soft tissue, so doctors often request lung CT scanning to get a good image of soft tissue including organs, muscles, blood vessels, nerves, and the brain. Sometimes a contrast dye is used as it shows up clearer on the screen.
During a quality CT scan of the lungs, cross sectional pictures of the chest, heart and upper abdomen are created.
Reasons for a lung CT scan:
CT scans are used for a multitude of reasons. They may be done to check for certain cancers in various different ways including to detect abnormal tumors, growths or lumps. They also identify the location of tumors, the stage of cancer, and where to perform a biopsy.
A lung CT scan can be used to guide doctors or surgeons during a procedure, such as a biopsy. They are important in planning for certain types of therapy and surgery, as well as in the aftermath to determine whether the patient’s lungs are responding to treatment.
CT scans can be used to detect cysts or infections in the lungs. They can also identify bronchiectasis, Pneumonia and Pulmonary TB.
A lung CT scan is often used to quickly inspect a patient after an accident in order to identify traumatic internal injuries.
A lung CT scan may help diagnose (find):
A lung CT may be done after a chest injury, to look for infection or inflammation in the chest or lungs, or to look for blood clots in the lungs.
A CT scan of the lung may diagnose blood vessel abnormalities, fluid buildup, an aneurysm, or enlarged lymph nodes.
The test may diagnose a widening of the large airways of the lungs.
A thoracic CT scan may show lung tumors, esophageal cancer or other tumors, nodules or cysts in the chest and/or lungs.
