New CT software programs allow rapid-sequence images to be obtained. During a period
of 12 sec, multiple CT images can be produced, so that the progression of contrast
flow at intervals of 1 sec or less can be followed. In addition, as many as 16 consecutive
3-sec scans can be performed, or arbitrary time intervals inserted between scans.
The rapidity with which the contrast medium enters and leaves a specific tissue may
be a valuable, non-invasive diagnostic tool in differentiating enhancing lesions.
Other potential applications are mentioned.
