A 50-year-old man with postprandial abdominal pain, weight loss, and generalized body ache was referred to Nuclear medicine department for a whole body bone scan to look for any malignancy. Clinical examination did not reveal any specific positive findings. He underwent aTechnetium-99m Methylene Diphosphonate (99mTc-MDP) bone scan which showed no obvious bone pathology. But there was...

a 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with loomci of iodine-131 and negative whole body scans was referred for follow up study. tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. the patient was operated, the parathyroid adenoma was removed. in thi...

OBJECTIVE Protocols for monitoring patients with differentiated thyroid cancer (DTC) include measurement of serum Tg and, for most patients, whole-body scan (WBS) with low radioiodine activities ('diagnostic' WBS). Recently, recombinant human thyroid-stimulating hormone (rhTSH) has become available to provide the TSH stimulation necessary for these procedures, whilst avoiding thyroid hormone wi...

UNLABELLED Recombinant human thyroid-stimulating hormone (rhTSH) is effectively used for exogenous thyroid-stimulating hormone (TSH) stimulation before diagnostic (131)I scintigraphy. It is not yet widely used for preparation of patients receiving a therapeutic amount of radioiodine. METHODS The results of 64 consecutive therapeutic applications of rhTSH with regard to clinical tolerance and ...

Radioiodine therapy is commonly used in hyperthyroid cats and has a high success rate, ranging from 85-95%. As in humans, thyroid volume has been reported to influence radioiodine therapy outcome in hyperthyroid cats. The purpose of this study was to relate total thyroid volume, calculated by a newly constructed formula for feline patients (0.438 × length × width²), to the outcome of radioiodin...
