AI grows up in cancer imaging—autonomy, with caveats
This review tracks how oncologic imaging has shifted from hand-crafted feature engineering to deep learning systems that can extract clinically meaningful patterns directly from pixels. It argues that imaging now sits at the center of most cancer decisions, and that the next step is “autonomous diagnostic workflows”—end-to-end pipelines that detect, characterize, and help triage findings across radiology and histopathology. The piece emphasizes that these systems are evolving from tools that assist interpretation to workflows that can take on parts of the diagnostic process, with implications for validation, governance, and integration into clinical practice.
Why it might matter to you:
Imaging AI is increasingly being packaged as workflow, not just software—changing what “good evidence” looks like (e.g., performance across sites, scanners, and populations, and the impact on triage and reporting). Even outside oncology, the same autonomy-and-safety questions apply to ultrasound and procedural imaging: how to validate models, set thresholds, and design human-in-the-loop checks that reduce misses without creating alert fatigue.
Hidden cardiac strain in paediatric epilepsy, spotted by speckle-tracking
A Pediatric Research study reports that speckle-tracking echocardiography can detect subclinical cardiac dysfunction in children with drug-resistant epilepsy—changes that may not be apparent on standard measures. By focusing on myocardial deformation (strain) rather than only conventional function parameters, the work highlights a potentially more sensitive approach to identifying early cardiac involvement in a neurologic population. The findings add to growing interest in cardiovascular surveillance in conditions where chronic disease burden and treatment exposures may have systemic effects.
Why it might matter to you:
This is a reminder that “normal-looking” conventional imaging can still miss physiologically meaningful dysfunction—an idea that translates well to musculoskeletal imaging when subtle tissue mechanics or early pathology are suspected. It also underscores how advanced quantitative imaging metrics can shift screening and risk discussions, particularly for patients with complex comorbidities.
Microglia, TREM2, and glaucoma: an imaging-led path to mechanism
Using single-cell transcriptomics of human glaucomatous retinas, investigators identify a disease-associated microglia population marked by high TREM2 expression alongside other neurodegeneration-linked genes. These microglia show programs enriched for phagocytosis, antigen presentation, and immune regulation, suggesting an active role in retinal degeneration rather than a passive bystander response. The study reports that loss of TREM2 impairs microglial function and worsens retinal neurodegeneration, positioning this pathway as a potential lever for modifying inflammatory components of glaucoma.
Why it might matter to you:
Mechanistic papers like this often drive the next wave of imaging biomarkers—linking cellular states to structural or functional readouts that clinicians can follow over time. It also highlights a broader pattern across degenerative disease: immune-cell phenotypes can be “disease-associated,” which may influence how future imaging endpoints are selected for trials and monitoring.
