What can CT imaging show us?

UCSF Radiologist Dr. Yeh describes what a CT scan is and how CT imaging helps with cancer imaging and cancer diagnosis.

CT scanner was developed by Dr. Hounsfield who realized that we could make a rotational X-rays around the patient. X-rays will be sent through the patient through detectors behind the patients by circling this x-ray source.  Doctors can digitally synthesize a cross-sectional slice through the human body that’s only a few millimeters thick. X-ray will pass through objects that are less dense more easily so air will be black.
