CAT scan
Cross-sectional X-ray
A CAT scan is a medical imaging procedure that uses X-rays and computer processing to create detailed cross-sectional images of the body.
CAT stands for computerized axial tomography; the procedure is also called a CT scan.
Doctors order CAT scans to examine internal organs, bones, and soft tissues: The CAT scan revealed a small tumor on his kidney.
