Simulation‐free spine palliative radiotherapy enabled by AI‐adapted diagnostic CT

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Radiotherapy planning traditionally requires a dedicated simulation CT (sCT), which can introduce delays in initiating treatment. This is particularly impactful in spinal palliative care, where timely treatment is often important for symptom control and prevention of neurological deterioration.

A universal framework for IMRT dose prediction

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Dose prediction has great potential in improving plan quality and efficiency by estimating optimal dose distribution. However, most existing deep learning (DL) based dose prediction models for intensity‐modulated radiation therapy (IMRT) have been primarily developed under simplified conditions, such as fixed beam configuration and ...

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

NMR 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.

Non‐Invasive, High‐Resolution (1H2O) Metabolic Activity Diffusion Imaging [MADI] of Rat Glioma

NMR in Biomedicine, Volume 39, Issue 3, March 2026.
We employed Metabolic Activity Diffusion Imaging [MADI] and 18FDG‐PET in rats with syngeneic RG2 glioblastoma brain tumors. MADI quantifies kio (the cellular H2O efflux rate constant), cell volume (V), and cell density (ρ), without the use of contrast agents. The kioV product quantifies the rate of water efflux per cell.

Concurrent ANNPE and vertebral T‐cell lymphoma in a dog: A case report

Journal of Small Animal Practice, Volume 67, Issue 3, Page 289-293, March 2026.
Acute non‐compressive nucleus pulposus extrusion (ANNPE) is a recognised cause of peracute spinal cord injury in dogs, involving sudden extrusion of non‐degenerated nucleus pulposus with minimal compression. While often linked to vigorous activity, its triggers remain unclear.

Brain Dose–Volume Thresholds and Survival in Dogs With Intracranial Tumours Treated With the 10 × 4 Gy Radiotherapy Schedule: A Combined Analysis of Two Trials

Veterinary and Comparative Oncology, Volume 24, Issue 1, Page 177-185, March 2026.
ABSTRACT Dogs with intracranial tumours routinely receive radiotherapy, yet species‐specific dose–volume constraints for normal brain tissue remain undefined. In human radiation oncology, exceeding certain brain dose–volume thresholds markedly increases the risk of radiation‐induced injury (e.g., radionecrosis).
