Malignancy in Pediatric Hyperfunctioning Thyroid Nodules: A Case Report and Literature Review

Clinical Endocrinology, EarlyView.
ABSTRACT Background Thyroid nodules are rare in children but carry a markedly higher risk of malignancy compared to adults (20%–26% vs. 5%). Hyperfunctioning thyroid nodules are exceptionally uncommon in the pediatric population and are typically benign.

Diagnostic performance of ultrasonography, dual-phase 99mTc-MIBI scintigraphy, early and delayed 99mTc-MIBI SPECT/CT in preoperative parathyroid gland localization in secondary hyperparathyroidism

BMC Medical Imaging, 2020
Background Secondary hyperparathyroidism (SHPT) usually requires parathyroidectomy when drug regimens fail. However, obtaining an exact preoperative map of the locations of the parathyroid glands is a challenge.

Diagnostic Options in Graves' or Non‐Graves' Thyrotoxicosis: A Review for Clinical Practice

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Distinguishing Graves' disease (GD) from the other causes of thyrotoxicosis is essential for appropriate management. The clinical phenotype of GD has evolved over time and is currently more heterogenous and milder than in the past. Consequently, the differential diagnosis of thyrotoxicosis is often challenging.

A Study on Predicting Split Renal Function Using Renal Blood Flow Weighted Estimated Glomerular Filtration Rate From Arterial Spin Labeling MRI

Journal of Magnetic Resonance Imaging, Volume 64, Issue 3, Page 712-721, September 2026.
ABSTRACT Background Traditional methods for evaluating split renal function, including contrast‐enhanced CT and radionuclide imaging, have limitations related to ionizing radiation or potentially nephrotoxic contrast agents. Purpose To investigate the value of renal blood flow (RBF)‐weighted estimated glomerular filtration rate (eGFR) derived from ...

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Chelator Free Radiolabeling and Preclinical Evaluation of η6‐Arene Sandwich Complexes of Lenalidomide With Rhenium and Technetium‐99m

ChemBioChem, Volume 27, Issue 16, 27 August 2026.
Direct, chelator‐free radiolabeling of lenalidomide is achieved via η6‐arene coordination to technetium‐99m and rhenium, forming sandwich complexes. The radiotracer shows rapid blood clearance, predominant renal excretion, and good in vivo stability, highlighting its potential as a pharmacokinetic probe.

Scanner‐agnostic artificial intelligence approach for fast bone scintigraphy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Purpose Current bone scintigraphy protocols often demand full‐count, 10–15 min scans to preserve image quality, and existing deep‐learning (DL) denoisers typically need to be retrained or retuned for each camera manufacturer. We introduce a scanner‐agnostic adaptive‐diffusion U‐Net designed to reconstruct diagnostic‐grade images from half‐time
