Generation of an Age‐Dependent and Harmonized 18F‐FDG Brain PET Atlas Using a High‐Sensitivity Short‐Axial FOV PET/CT System

open access: yesHuman Brain Mapping, Volume 47, Issue 4, March 2026.
Age‐stratified and scanner‐harmonized 18F‐FDG brain PET atlases were generated from high‐sensitivity PET/CT data. The framework integrates EIR‐based harmonization, spatial normalization, and age‐specific averaging to enable cross‐scanner comparability and provide normative metabolic references across the adult lifespan. ABSTRACT 18F‐FDG brain PET atlas

Porous Nanocellulose‐Reinforced Polyacrylamide Hybrid Hydrogels for Tissue Engineering

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 2, March 2026.
Porous polyacrylamide‐nanocellulose hydrogels fabricated via NaHCO3 driven gas foaming, enabling tunable pore architectures. Increasing porosity enhances swelling behavior and supports human chondrocyte adhesion, infiltration, and distribution, while the scaffolds retain high mechanical resilience and compressibility.

A prescription‐free, radiobiology‐based framework for automated VMAT planning: A feasibility study in primary prostate cancer radiotherapy

open access: yesMedical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Current VMAT planning workflows for prostate cancer primarily depend on conventional dose–volume criteria specified at discrete dose or volume points. These point‐based objectives, however, do not necessarily lead to globally optimal, patient‐specific treatment plans.

Band‐Selective IR PRESS for Brain Tumor Spectroscopy Allows Robust Detection of Lactate

open access: yesNMR in Biomedicine, Volume 39, Issue 3, March 2026.
Lactate quantification by MRS is hindered by lipid signal overlap at 1.3 ppm, frequently forcing the use of long echo times that suppress other metabolites. We developed SPIR‐PRESS, a selective inversion recovery technique that suppresses lipids while preserving metabolite sensitivity.
