Aim: This study aimed to determine the normal range for thyroid uptake of technetium-99m (99mTc) pertechnetate in a Turkish population.Methods: The retrospective included 73 (54 females, 19 males) consecutive euthyroid patients, all whom underwent scintigraphy using 99mTc-pertechnetate as component parathyroid adenoma localization. value at 20th minute was calculated each patient.Results: mean ...

Askin tumor is a rare disease which had previously been reported as being thallium-201 and gallium-67 avid. Varying data regarding 18F- fluorodeoxyglucose metabolism has been described with Ewing family of soft tissue tumors. In this case, we present a patient found to have an Askin tumor of the left chest wall which demonstrated indium-111 pentetreotide and technetium-99m MIBI avidity. The les...

INTRODUCTION Preoperative accurate localization of enlarged adenoma (s) in primary hyperparathyroidism (PHPT) is a vital necessity. Technetium 99m sestamibi scanning is commonly used with reported acceptable sensitivities; however, false negative scan studies remain a problem. Determining effective factors on the sensitivity of the scan might improve the diagnostic value of the study by selecti...

The radiotracer technetium-99m methoxyisobutyl isonitrile ((99m)Tc-MIBI) has been widely used for myocardial blood flow imaging. We investigated the genotoxicity of (99m)Tc-MIBI in cultured human lymphocytes at the same concentration used in patients. Radioactivity doses were determined in whole blood at 5 min post-injection of 20 mCi (99m)Tc-MIBI in patients. Subsequently, whole blood of human...

We report here a rare case of primary hyperparathyroidism that was associated with an ectopic parathyroid adenoma located in the mediastinum. A 66-year-old woman suffering from primary hyperparathyroidism had been followed-up on an outpatient basis for over 10 years. She suffered from persistent urolithiasis and osteopenia due to hypercalcemia. After technetium-99-sestamibi (99mTc-MIBI) scintig...

OBJECTIVES To analyze the predictive values of selective venous sampling (SVS) in our own experience and in a systematic meta-analysis of the international literature and to compare them with the results of noninvasive localization studies before reoperative parathyroid surgery. DATA SOURCES Twenty-one consecutive patients with persistent or recurrent renal hyperparathyroidism underwent preop...

CONTEXT Preoperative localization of parathyroid adenoma is essential in deciding the surgical approach of parathyroidectomy. AIM To describe clinical and biochemical profile, evaluate preoperative imaging modalities and surgical approach in patients with primary hyperparathyroidism (PHPT). METHODOLOGY This was a retrospective study conducted at the single institution. All patients who unde...

A 34 year old woman with malaise, polyuria and nocturia as well as nausea and vomiting referred to perform a thyroid scan due to right thyroid lobe mass. The scan showed a cold nodule in the right thyroid lobe. Serum calcium of 16.9, serum phosphorus of 1.8 and PTH of 1156 were noticed in laboratory tests. Parathyroid scan with 99mTc-MIBI showed no abnormal tracer activity in the nec...
