Joyet, G

With the aid of a sthtistics in 222 cascs, it is shown, that the initial tangent T'/sub o/ of the radioiodine uptake curve, after intravenous injection of radioactive iodine, is the determining element for the differentiation of normal and pathological thyroid behavior. A new instrument is described with two scintillation counters, which enables the correct determlnation of T'/sub o/ on the reclining patient, after an injection of 10 to 20 microcuries of I/sup 131/. A main counter, properly suspended with an appropriate collimator nnd an optical adjustment for determining the distance, measures the activity of the thyroid and the neck. A second counter enables the determination of the correction for the extrathyroidal activity, based on measurements on the thigh and around the thyroid. This correction is essential for obtaining an accurate determination of the initial uptake rate of the thyroid. (auth)
