Clinical Use of a Positron Camera System
In the field of emission tomography (ET) two lines of development can be discerned : one aims at dynamic or physiologic studies, best carried out using positron-emitting isotopes as well as a 4-dimensional instrument, i.e. a positron camera, allowing the parameter of interest to be studied simultaneously in three dimensions of space as well as with time (1) ; the other seeks to demonstrate changes of a more static nature — morphological or pathological — anatomical. In Stockholm, clinical work with the present positron camera system (2,3) has mainly followed this latter line. However our group is at the same time trying to acquire the necessary resources for physiological investigations. A 4-dimensional instrument is being constructed (4) and efficient methods of labeling carbon hydrates (5) and polypeptides (6) have been devised.
