Association Between Deep Gray Matter Iron Deposition Dysregulation and Cognitive Performance in Type 2 Diabetes Mellitus Patients: A Quantitative Susceptibility Mapping Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Type 2 diabetes (T2DM) heightens cognitive impairment risk, yet the mechanisms remain unclear. Hyperglycemia‐induced iron dysregulation in deep gray matter (DGM) nuclei may be a crucial mechanism. Purpose To investigate DGM iron deposition in T2DM using Quantitative Susceptibility Mapping (QSM) and determine its association with ...

Assessment of Thyroid Uptake Ratio Values in a Normal Population. Establishment of Normal Reference Values for 99mTc‐Pertechnetate Thyroid Uptake in an Australian Population

Journal of Medical Radiation Sciences, EarlyView.
An Australian first, this study examined normal reference ranges for 99mTc‐pertechnetate thyroid uptake. Through a retrospective and prospective analysis, this study found a new reference range of 0.4%–2.4%. The findings suggest that locally derived reference values may differ from historical data and highlight the importance of region‐specific ...

Imaging modalities demonstrate moderate and heterogeneous diagnostic accuracy for periprosthetic joint infection: A systematic review and meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The diagnostic accuracy of imaging modalities in periprosthetic joint infections (PJIs) remains uncertain. This study assessed and compared the performance of different imaging techniques for diagnosing PJI. Methods A systematic review and meta‐analysis of studies published in PubMed and Embase (1 January 2000 to 1 March 2024) was ...
