National survey of imaging technologists in nuclear medicine 1998/99.

abstract：OBJECTIVE:The recent development of mixed ligand complexes using a 99mTc tricarbonyl synthon has prompted us to revisit the first generation product, 99mTc-t-butyl isonitrile (TBI), for possible myocardial imaging after modification of the 99mTc core to a mixed ligand core of carbonyl and t-butyl isonitrile. The easy a...
