What is spiral CT?

A spiral (or helical) CT scan is a new kind of CT. During a spiral CT, the x-ray machine rotates continuously around the body, following a spiral path to make cross-sectional pictures of the body. Benefits of spiral CT include:

* It can be used to make 3–dimensional pictures of areas inside the body;
* It may detect small abnormal areas better than conventional CT; and
* It is faster, so the test takes less time than a conventional CT.
