MicroPET imaging of gene transfer with a somatostatin receptor-based reporter gene and (94m)Tc-Demotate 1.

These studies show that the positron-emitting somatostatin analog (94m)Tc-Demotate 1 could be used to determine SSTR2 gene transfer by microPET imaging, a result that will improve the sensitivity of the SSTR2 reporter gene system.
