(A) Averaged parametric images of F-18 SynVesT-1 BPND values and (B) F-18 FDG SUVR (60–90 minutes) values overlaid on anatomical (T1) images in MNI space show group differences between behavioral variant frontotemporal dementia (top) and healthy controls (middle). The color scale represents (A) BPND and (B) SUVR values. On the bottom, average z-score maps were generated to visualize regional reductions in F-18 SynVesT-1 BPND and F-18 FDG SUVR in bvFTD relative to healthy controls. For each voxel, z-scores were calculated as z = (bvFTD−meanHC )/SDHC. Negative z-scores indicate lower synaptic density or glucose metabolism in the bvFTD compared with controls in the regions. BPND, non-displaceable binding potential; bvFTD, behavioral variant frontotemporal dementia; F-18 FDG, F-18 fluorodeoxyglucose; MNI, Montreal Neurological Institute; SUVR, standardized uptake value ratio.

New method decouples Alzheimer's disease pathology at PET

AI-derived scoring tool shows independent associations, according to researchers.

April 7, 2026

Adversarial decomposition learning (ADL) enables intuitive, longitudinal visualization of disease progression and treatment response, supporting clinician–artificial intelligence collaboration. (A) Images in a 48-year-old female patient who presented with mild cognitive impairment. The ADL probability maps highlighted occipital-temporal amyloid β (Aβ) spread and focal left-temporal tau pathologic abnormalities. An area of increased occipital AV45 uptake is shown (arrowhead). (B) Images in a 51-year-old male who presented with memory decline. For each image grid, the left side is the decoupler-output AD pathologic probability map, the upper right side is the original Aβ/tau PET image, and the lower right side is the image after AD component removal by the decoupler.

AI estimates children’s bone density on chest x-rays

A study highlights the potential of an AI model as a tool for opportunistic bone health screening in children at risk for skeletal deficits.

Representative example of a 16-year-old male patient with underlying X-linked adrenoleukodystrophy. (A, B) Paired anteroposterior (AP) chest radiograph and dual-energy x-ray absorptiometry (DXA) report shows lumbar spine (L1 through L4) areal bone mineral density (BMD). The DXA report was reformatted for anonymization and improved readability. The patient had low BMD (Z score ≤ −2.0). (C) Model (chest radiography [CXR]–BMD) output shows the predicted raw BMD and Z score in comparison with the DXA reference standard, together with interpretability analyses using Shapley additive explanations (SHAP) and gradient-weighted class activation maps. The patient was classified as having low BMD, consistent with the reference standard. AM = age-matched, DEXA = dual-energy x-ray absorptiometry, RM2 = room 2, SNUH = Seoul National University Hospital, YA = young adult.
