Detecting spread of non-small-cell lung cancer within the chest

Article Abstract:

PET scanning is more effective than CT scanning for identifying patients whose non-small-cell lung cancer has spread inside the chest, according to researchers who analyzed 39 studies covering over 2,500 patients. The only problem with PET scanning is that it may give a false-positive result in patients who have enlarged lymph nodes. For this reason, these patients should have a biopsy to confirm the scan.

Helical CT imaging is not yet accurate enough to diagnose pulmonary embolism. This type of imaging is done by rotating the CT machine around the patient. Pulmonary embolism is a blood clot that lodges in the lungs, causing chest pain, difficulty breathing, and even death.
