title: The preparation and stability of radioiodinated antipyrine for use in local blood flow determinations.
abstract: The accurate assessment of local blood flow by recording the washout of a deposit of radiolabelled 4-iodoantipyrine (4-IAP) requires the use of a stable radiopharmaceutical. This communication shows that it is possible to produce a 125I and 131I-4-IAP compound which fulfills this requirement under simulated conditions of use.
