A significant advancement in medical imaging is detailed in the January 16 issue ofย Nature Biomedical Engineering. Researchers from Caltech and USC have developedย Rotational Ultrasound and Photoacoustic Tomography (RUS-PAT), a novel hybrid technique that overcomes the fundamental limitations of standalone ultrasound and photoacoustic imaging to deliver rapid, co-registered 3D structural and functional data. The Core Innovation:ย Traditional […]

Beyond the 16-Week Snapshot: Why Data Snapshots Mask the Reality of Chronic Therapy
Beyond the 16-Week Snapshot: Why Data Snapshots Mask the Reality of Chronic Therapy In my independent review of the CARES-310 trial (Camrelizumab-Rivoceranib), I analyzed a common pitfall in modern drug development: the reliance on 16-week primary endpoints to justify long-term therapeutic narratives. While a 16-week data cut can deliver a clean p-value for a regulatory […]
