The present guidelines for nuclear medicine practitioners offer assistance in optimizing the diagnostic information from the SLN procedure. These guidelines describe protocols currently used routinely, but do not include all existing procedures. They should therefore not be taken as exclusive of other nuclear medicine modalities that can be used to obtain comparable results. It is important to remember that the resources and facilities available for patient care may vary.

The gastric emptying rate was measured in 10 female patients with primary anorexia nervosa and 12 healthy volunteers, using a scinti-scanning technique for the simultaneous study of the liquid and solid components of a test meal. The emptying rate of both the liquid and the solid phase components of the meal was significantly slower in patients with anorexia nervosa. The aetiological and therapeutic implications of this finding are discussed.
