Purpose Iodine-123 is a pure gamma emitter and has excellent characteristics for imaging
with modern scintillation cameras. The goal of this study was to compare the performance of …

Objective We assessed the performance of 37 MBq I-123 as a diagnostic imaging agent in
patients with differentiated thyroid cancer using comparisons with their corresponding high …

We performed a prospective random study to assess possible thyroid stunning by a 185-
MBq iodine-131 dose used to diagnose thyroid remnants. Patients with differentiated thyroid …

Purpose Using 123 I for diagnostic purposes avoids the risk of stunning for subsequent
radioiodine treatment and affords an excellent image quality. In this study we assessed the …

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 …

Detection of residual tissue after thyroidectomy for papillary or follicular thyroid carcinoma
may be performed using diagnostic imaging with either 123I or 131I. The former is often …

The merits of 123I as a thyroid scanning agent have been lauded since it became possible
to produce 123I using a cyclotron. In 1967, Rhodes et al.(1) stated:“In the past, the …

The aims of this study were to evaluate the efficacy of an empirically determined 'fixed'high
ablative dose of radioiodine (131 I) therapy and to determine the utility of ultrasonography …

This study was performed to determine differences in 123I image quality at 5 and 24 h for the
detection of residual thyroid or recurrent disease in patients with differentiated thyroid cancer …

Purpose The use of I-123 in lieu of I-131 for diagnostic whole-body thyroid tumor scanning
(DxRaI) in patients with differentiated thyroid cancer obviates the risk for stunning and …
