Why do CAT scan results take so long?

In most cases, a CT takes 10-30 minutes. But, depending on the reason for the scan, it can take 45 minutes to an hour. If your CT exam needs a contrast dye, the scanning appointment will take longer. The extra time comes from administering the contrast material and waiting for it to take effect.
