Fig. 6 The early technetium and radioiodine uptake in a euthyroid individual, The horizontal broken line at 3.75% indicates in this, and subsequent figures, uptakes. Fig. 7 the upper limit of normal for technetium BNL Neg. # 11-516-73 A patient with hyperthyroidism based on clinical evaluation and in-vitro tests shows the technetium uptake to be higher than the iodine uptake. The 24 hour radioiodine uptake was normal. BNL Neg. #11-728-73 Fig. 8 Uptake curves in a patient with hyperthyroidism. Note an iodine uptake of greater than 20% in less than 30 minutes. BNL Neg. #11-729-73 Fig. 9. Patient with suspected Hashimotos' thyroiditis. uptake at 24 hours was elevated. The radioiodine At 30 minutes it also seems high but no normal values for this technique have been established at this time, Note the early peaking and slow descent of the technetium curve, 500130} BNL Neg. #11-727-73
