Somatostatin-receptor scintigraphy has been in clinical use for severa
l years, Most of the experience with somatostatin tumor scintigraphy h
as been obtained with gastro-enteropathic (GEP) tumors and carcinoids,
Clinical applications of somatostatin imaging have been reported in s
mall-cell lung carcinomas, malignant lymphomas, renal-cell cancers and
cancers, Somatostatin analogues were initially applicable in larger m
edical institutions because of the necessity for radioactive labeling
with iodine (octreotide to [I-123-Tyr(3)]-octreotide); however, the cl
inical results with iodinated analogues were worse than the relatively
new analogue [In-111-DTPA-D-Phe(1)]octreotide, now available as Octre
oscan(R). This review describes the current status of the clinical app
lication of somatostatin receptor imaging, together with our own exper
ience in carcinoids, GEP tumors and medullary thyroid carcinomas.
