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 …

Background Follow-up of 131 I whole-body scanning after 131 I ablation is associated with
potential stunning. Previous studies have suggested that, for scanning, 123 I is more …

Comparison of 123I and 131I for thyroid scans and uptakes was undertaken to evaluate their
diagnostic values in conjunction with instrumental efficacy for 123I. By far the superior …

Purpose: In managing differentiated thyroid carcinoma, concern over the stunning that may
occur with traditional whole body imaging using I-131 has fostered an interest in using I-123 …

In patients with thyroid carcinoma, remnant thyroid tissue or metastases may have lower
131I uptake on posttherapy images than on prior diagnostic images. This observation has …

Objective To determine whether 123 I can be used as a safe and effective alternative tracer
to 131 I for imaging remnant tissue and for searching for metastatic lesions of well …

Among the 24 radioisotopes of iodine, only four, 123 I, 125 I, 131 I, and 132 I, have been
utilized clinically to any significant extent. Optimal use of radioiodine involves a …

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 …

This article discusses several aspects of the evaluation and management of differentiated
thyroid carcinoma that are changing or may change in the near future. Although …

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 …
