Innovations in Imaging: Transforming Diagnosis in Neurology and Cardiology

Clinicians are increasingly balancing earlier detection against overtesting and false positives as MRI, PET, and spectral CT are being woven into dementia and myocarditis pathways.

Integration into routine practice is steadily expanding, with careful attention to balancing precision against overtesting.

Against that tension between precision and overtesting, adoption is steadily expanding in routine practice: in dementia workups, MRI and PET help flag structural and functional changes such as hippocampal atrophy, while in a shared pathway pivot to the heart, spectral CT provides material-specific maps that support myocarditis assessment as described in dual-energy spectral CT and MRI reviews of myocarditis imaging.

Evidence is emerging rather than definitive: a recent article suggests AI-augmented neuroimaging may improve subtype classification accuracy in dementia, warranting cautious interpretation until peer-reviewed confirmation.

In cardiology, advanced sequences such as 4D flow MRI allow more granular hemodynamic assessment in select centers, while in neurology, portable light-based brain monitors are being explored as adjunctive screening tools rather than stand-alone diagnostics, with early reports highlighted by a news summary on portable optical monitors for dementia.

The clinical impact is more about enabling steps than proving outcomes: by mapping iodine within the myocardium, spectral CT can support more timely recognition of inflammation and alignment with targeted management pathways in suspected myocarditis, as outlined in spectral CT and MRI overviews of myocarditis imaging, without asserting direct causality.

Operational realities are shaping adoption: availability of scanners, radiologist expertise, and standardized protocols can either reduce unnecessary testing or inadvertently expand it if guardrails are unclear—reinforcing the lead tension.

Equity considerations are emerging as central: portable modalities may widen reach, but evidence and reimbursement pathways need to catch up to ensure benefits are distributed and that false positives do not cluster in underserved settings.

Next logical step: test these pathways where they matter. Multicenter pragmatic trials and real‑world registries should compare AI‑augmented dementia imaging against standard workups and evaluate whether spectral CT–informed myocarditis pathways accelerate diagnosis and equitable access, turning technical gains into measurable clinical value.

Key Takeaways:

• Clinical pathways are negotiating a live tension: moving detection earlier while minimizing overtesting and false positives.
• AI is poised to augment image interpretation, but current signals (including preprints) are preliminary and need peer‑reviewed confirmation.
• Material-specific imaging such as spectral CT can support more timely recognition and triage in suspected myocarditis without proving outcome causality.
• Portable optical monitors are exploratory adjuncts that may broaden access but are not stand‑alone diagnostics.
