Preoperative Technetium Tc 99m Sestamibi SPECT Imaging in the Management of Primary Hyperparathyroidism in Patients With Concomitant Multinodular Goiter [PDF]

Archives of Surgery, 2005
Preoperative parathyroid and thyroid imaging using technetium Tc 99m sestamibi scintigraphy-single-photon emission computed tomography (Tc 99m MIBI SPECT) and technetium Tc 99m sodium pertechnetate, respectively, in patients with parathyroid adenomas and concomitant multinodular goiters enables the selection of those suitable for minimally invasive ...

From [^99mTc]pertechnetate to [^99mTc]sestamibi: Dissection of a Complex Reaction Sequence Using Radio-LC-MS

Molecules
[99mTc]sestamibi ([99mTc][Tc(MIBI)6]+; MIBI = 2-methoxybutylisonitrile) is a clinically established myocardial perfusion SPECT tracer. Its one-pot kit-based synthesis from [99mTc]pertechnetate ([99mTc][TcO4]−) is complex, involving a 6-oxidation state ...

Relative Contributions of Technetium Tc 99m Sestamibi Scintigraphy, Intraoperative Gamma Probe Detection, and the Rapid Parathyroid Hormone Assay to the Surgical Management of Hyperparathyroidism [PDF]

Archives of Surgery, 2000
Technetium Tc 99m sestamibi scintigraphy, intraoperative gamma probe detection, and the rapid parathyroid hormone assay have been used to permit a directed operation in patients with hyperparathyroidism. We hypothesized that the coordinated use of these techniques might be particularly useful in patients who require a second operation for ...

Disproportionate Elevated Troponin T Without Clinical Ischemia: A Diagnostic Challenge in the Emergency Department

Case Reports in Medicine, Volume 2026, Issue 1, 2026.
Background Cardiac troponins (cTns) are essential for evaluating chest pain, but elevated levels can arise from noncardiac causes or laboratory artifacts. Confirmatory testing for assay interference is often unavailable for false‐positive cases, complicating diagnosis and management.

Severe Hypercalcemia as Presentation of Atypical Cystic Parathyroid Adenoma: A Case Report

Annals of Internal Medicine: Clinical Cases
Because of their similarities with parathyroid carcinomas, atypical parathyroid adenomas constitute a challenge for pathologists. The diagnosis of this kind of parathyroid tumor also can be difficult for clinicians because of the low accuracy of imaging ...

Brown Tumors Mimicking Skeletal Metastases: A Diagnostic Pitfall in Primary Hyperparathyroidism

Clinical Case Reports, Volume 13, Issue 12, December 2025.
ABSTRACT Brown tumors are rare but important manifestations of primary hyperparathyroidism (PHPT). These benign, fibrotic, and erosive bony lesions result from localized rapid osteoclastic activity driven by excessive parathyroid hormone levels. Although brown tumors are considered one of the most pathognomonic signs of PHPT, they are infrequently ...
