Aim The aim of this paper was to explore by a quantitative method whether a 74 MBq 131I
scanning activity produces a stunning effect in patients with differentiated thyroid carcinoma …

" Thyroid stunning" from diagnostic iodine-131 imaging prior to ablative therapy with 131 I for
well-differentiated thyroid carcinoma has been well reported, but documentation of the effect …

Objective: Dosimetry studies have shown that activities of 131 I as small as 10-20 MBq may
cause a stunning effect. A result of this stunning effect may be a lower success rate of the …

PURPOSE: To determine if stunning can be seen with a 185-MBq (5-mCi) dose of iodine
131 (131I) at diagnostic whole-body scanning and, if stunning is seen, determine if there is …

Aim: To understand stunning effects of a diagnostic dose of iodine-131 (1-131). Methods:
Four hundred and sixty-eight patients (101 males, 367 females, ages: 6-75 years) with well …

BACKGROUND: An obvious paradox remains in the diagnosis, treatment and follow-up of
differentiated thyroid cancer by 131 I. The higher the activity for raising diagnostic precision …

When thyroid tissues exhibited concentrations of therapeutic 131I that appeared to be less
than that predicted by data from the preceding diagnostic 131I, the phenomenon was called …

I read with interest the paper by Sabri et al.[1]. In patients given two-step radioiodine therapy
for benign thyroid disease, they quantified 32% lower mean thyroid uptake after 435±232 …

Purpose Stunning of thyroid remnants after diagnostic scanning (Dx-WBS) using radioactive
iodine-131 (131 I) may limit the efficacy of 131 I therapy. We aimed to evaluate this …

The use of 131I in doses of several mCi for scans can stun the thyrocytes and thyroid cancer
cells, whereas the usual dose (300 μCi) of 123I does not. We compared the diagnostic …
