In addition to the actual scan time, people undergoing a CT scan must account for preparation time. One preparation that can take a little time occurs when contrast dye must be used for the scan. In most cases, the entire appointment should take under an hour, according to the University of Arkansas for Medical Sciences. A CT scan is an outpatient exam that doesn't usually require any recovery time.
