Top 10 this week

Week of 20 September 2026

  1. 1

    Cost-utility of NeuroSAFE-guided RARP Versus Standard RARP in Men with Localised Prostate Cancer in the UK

    European urology open science · Q1 journal · RCT · Evidence level 1 (High) · 9 September 2026

    In a trial of 407 men, the nerve-sparing NeuroSAFE technique added about £800 in NHS costs and improved quality-adjusted life expectancy by 0.03 QALYs, yielding an incremental cost-effectiveness ratio of roughly £26,000 per QALY. The result sits near the upper UK willingness-to-pay threshold, but considerable uncertainty remains, especially beyond the 12-month follow-up.

  2. 2

    Low-Dose Radiation Therapy (LDRT) for Osteoarthritis: A Retrospective Study of 94 Patients and 136 Joints Treated

    Advances in radiation oncology · Q1 journal · RCT · Evidence level 1 (High) · 21 May 2026

    In a retrospective series of 94 older adults (average age 74) treated on 136 joints, six fractions of 0.5 Gy lowered the average pain score from 7.3 to 2.6 on a 0-10 scale. Nearly four-fifths achieved a clinically meaningful improvement, regardless of age, sex or joint size, suggesting a safe, non-invasive option pending confirmatory trials.

  3. 3

    Delivered-Dose Validation of Nonadaptive Diagnostic Computed Tomography-Based Volumetric Modulated Arc Therapy for Simulation-Free Palliative Radiation Therapy

    Practical radiation oncology · Q1 journal · Retrospective cohort · Evidence level 3 (Low) · 16 September 2026

    In a retrospective study of 30 plans, the delivered dose on first-fraction cone-beam CT was 99.6% of the planned dose on diagnostic CT, with all treatments achieving at least 97% of the intended coverage. Target coverage and organ-at-risk doses were preserved across spinal and pelvic sites, supporting wider use of simulation-free VMAT in palliative care.

  4. 4

    Monte Carlo intercomparison of TG-43 dosimetric parameters for clinical192Ir and125I brachytherapy sources

    Physics in medicine and biology · Q1 journal · Unclassified · Evidence level 5 (Expert Opinion) · 15 September 2026

    Monte Carlo intercomparison of TG‑43 parameters for 192Ir and 125I

  5. 5

    A Modular Multi-Agent Reinforcement Learning Framework Guided by LLMs: Improving Quality and Efficiency of Treatment Planning in Lung Radiotherapy

    International journal of radiation oncology, biology, physics · Q1 journal · Unclassified · Evidence level 5 (Expert Opinion) · 17 September 2026

    Hybrid LLM‑RL framework improves lung IMRT planning efficiency

  6. 6

    Measurement-anchored Monte Carlo prediction of diagnostic x-ray air kerma using HVL-matched spectra and per-electron normalization

    Medical physics · Q1 journal · Unclassified · Evidence level 5 (Expert Opinion) · 1 October 2026

    Measurement‑anchored Monte Carlo prediction of x‑ray air kerma

  7. 7

    Beyond the snapshot: continuous optical surface monitoring reveals non-linear temporal dynamics and postural stability window in free-breathing breast radiotherapy

    Frontiers in oncology · Q2 journal · Cohort · Evidence level 3 (Low) · 3 September 2026

  8. 8

    Real-time tumor tracking for magnetic resonance-guided radiotherapy using label-efficient foundation model adaptation

    Physics and imaging in radiation oncology · Q1 journal · Unclassified · Evidence level 5 (Expert Opinion) · 10 September 2026

    MedSAM2 adaptation enables real‑time cine‑MRI tumor tracking

  9. 9

    Highly Accelerating Joint Intracranial and Carotid Vessel Wall Imaging Using ESPIRiT-Driven Diffusion Model Reconstruction

    Magnetic resonance in medicine · Q1 journal · Unclassified · Evidence level 5 (Expert Opinion) · 14 September 2026

    ESPIRiT‑Driven diffusion reconstruction for accelerated vessel wall imaging

  10. 10

    Inter-crystal scatter recovery of a light-sharing depth-encoding Prism-PET prototype scanner using a diffusion model

    Medical physics · Q1 journal · Unclassified · Evidence level 5 (Expert Opinion) · 1 September 2026

    Inter‑crystal scatter recovery for Prism‑PET prototype, diffusion model
