Breast HealthCT scanningComputed tomography, or CT scanning, uses a computer to organize and stack the information from multiple x-ray, cross-sectional views of a body's organ or area. The scans are made by having the source of an x-ray beam rotate around the patient. X-rays passing through the body are detected by sensors that pass the information to computers. Once processed, the information is displayed as an image on a video screen. CT can separate overlapping structures precisely and is sometimes helpful in locating breast abnormalities that are difficult to pinpoint with mammography or ultrasound--for instance, a tumor that is so close to the chest wall that it shows up in only one mammographic view.
