Exploring the prevalence and causes of normal Tc 99m thyroid uptake in thyrotoxic patients A retrospective study at a regional hospital of nuclear medicine in Oman

Abstract

This study focuses on assessing the prevalence of normal Technetium-99m (Tc-99m) Thyroid uptake scans among thyrotoxic patients at a specific medical facility in Oman, named "Royal hospital-nuclear medicine department". Thyrotoxicosis is a condition characterized by high levels of thyroid hormones in the body which is usually reflects as a high uptake in Tc-99m Thyroid Pertechnetate uptake scan. However, in some cases the scan shows normal thyroid activity which may lead to misdiagnosis or delayed treatment.
