A new cholescintigraphic agent: ruthenium-97-DISIDA.
These are the first human experiments with 97Ru-DISIDA, a potentially new alternative to 131I-rose bengal where delayed imaging is indicated. 97Ru has a convenient half life. A DISIDA labeling kit was utilized to prepare the radiotracer for 17 patients (age 6 weeks-84 years). The cholescintigraphic data correlated well with other imaging procedures and with clinical findings. Dosimetric calculations were carried out and were compared with the radiation burden associated with the use of 99mTc-DISIDA and 131I-rose bengal.
