How small of a tumor can a CT scan detect?
The primary limitation of CT scanning is its resolution, approximately 1 centimeter. A cancer smaller than this cannot be easily detected using this technique. However, recently developed scanners such as “helical” and “spiral” CT scanners are able to detect smaller masses.
How accurate is CT scan for cancer?
A cancer diagnosis based on CT scan has the potential to be completely wrong – up to 30% of the time! That means that 30% of the time people will either be told they don’t have cancer when they do… or people will be told they do have cancer when they don’t, based on CT scans alone.
How long does a whole body scan take?
The technologist may ask you to change positions during the scan. This helps to get pictures from different angles. A whole-body bone scan takes about 1 hour to finish. The scan is not painful.

How long does a full body scan take for cancer?
