Co‐pathologies and biological processes beyond amyloid‐beta and tau in people with Alzheimer's disease: Evidence from clinical cohort studies

Journal of Internal Medicine, Volume 299, Issue 6, Page 694-710, June 2026.
Abstract Alzheimer's disease (AD) is neuropathologically defined by amyloid‐beta (Aβ) plaques and tau neurofibrillary tangles. However, co‐pathologies and other pathobiological processes are involved in the pathogenesis of AD, contributing to neurodegeneration and clinical symptoms.

Functional Connectivity, Tissue Microstructure, and T2 at 11.1 Tesla Distinguishes Neuroadaptive Differences in Two Traumatic Brain Injury Models in Rats: A Translational Outcomes Project in NeuroTrauma (TOP-NT) UG3 Phase Study

Neurotrauma Reports
Traumatic brain injuries (TBIs), particularly contusive types, are associated with disruptions in neuronal communication due to focal and diffuse axonal injury, as well as alterations in the neuronal chemical environment.

Assessment of skeletal structure by MR relaxometry

, 1999
Introduction: More than 40 per cent of all women older than 50 years will suffer from a hip, wrist or vertebral fracture. Most of these fractures are related to bone fragility, osteoporosis.

1H NMR Spin-Lattice Relaxometry of Cement Pastes with Polycarboxylate Superplasticizers

, 2020
1H spin-lattice relaxometry (T1, longitudinal) of cement pastes with 0 to 0.18 wt % polycarboxylate superplasticizers (PCEs) at intervals of 0.06 wt % from 10 min to 1210 min was investigated. Results showed that the main peak in T1 relaxometry of cement

Abbreviated Multiparametric MR Solution (the “Liver Triple Screen”), the Future of Non-Invasive MR Quantification of Liver Fat, Iron, and Fibrosis

Diagnostics
Background/Objectives: To review the findings of a multiparametric MRI (the “liver triple screen”) solution for the non-invasive assessment of liver fat, iron, and fibrosis in patients with chronic liver disease (CLD). Methods: A retrospective evaluation

Diamond based relaxometry for biosensing

, 2022
FNDs show spin-dependent fluorescence allowing quantitative detection of electron spins and in certain cases even nuclear spins at ambient conditions by optical readout. FNDs emit stable fluorescence without photobleaching or photo blinking, far-red emission, long lifetime, and high quantum efficiency.

Multivariate Analysis Relating Oil Shale Geochemical Properties to NMR Relaxometry

, 2015
Low-field nuclear magnetic resonance (NMR) relaxometry has been used to provide insight into shale composition by separating relaxation responses from the various hydrogen-bearing phases present in shales in a noninvasive way. Previous low-field NMR work

Differentiating hippocampal subregions by means of quantitative magnetization transfer and relaxometry: preliminary results

, 2004
The hippocampal formation (HF) of healthy control subjects and schizophrenic patients was examined using an MRI experiment that implements sequences for relaxometry and magnetization transfer (MT) quantification.

T2-weighted and T2 relaxometry images in patients with medial temporal lobe epilepsy

, 2015
Purpose. Quantification of increased T2-weighted MRI signal that is associated with hippocampal sclerosis (HS) can be performed through (1) mean of hippocampal signal in single-echo T2 MRI and (2) hippocampal T2 relaxometry. It is not clear whether these
