Applications of condensed dynamic images.

In appropriate cases, information from a dynamic series of nuclear images may be condensed into a single image with one spatial and one temporal dimension. A useful elaboration of the method consists of the masking out of undesired spatial regions. The versatility of such condensed dynamic images is illustrated by examples derived from gastroesophageal and pulmonary studies. Advantages of the method include obviating the need to examine and comprehend multiple images as well as enabling economical archiving of image data. Its diagnostic potential is particularly evident in esophageal transit and infant gastroesophageal reflux studies.
