BIOLOGICAL EVALUATION OF 123I-PMPDA, A RADIOPHARMACEUTICAL
The distribution dynamics and functional suitability of 15-(p-123I, iodophenyl)-3-methylpentadecanoic acid (123I-PMPDA) were studied. The biological behavior of 123I-PMPDA is characterized by a pronounced selective accumulation of the radiopharmaceutical in the heart. Rabbit experiments yielded a high-quality scintigram of the rabbit heart. The viability of some myocardial portions can be judged from the cardiac accumulation of 123I-PMPDA.
