Cardiac CT, MRI, and PET in 2023: Exploration of Key Articles across Imaging and Multidisciplinary Journals

This is a field dispatch — a year-in-review of the most notable 2023 papers across cardiac CT, MRI, and PET, written to help busy clinicians keep pace.

The throughlines the authors pull out capture where non-invasive cardiac imaging is heading: photon-counting CT sharpening resolution, artificial intelligence creeping into image analysis and interpretation, head-to-head prognostic comparisons between MRI and PET, and the growing use of several modalities in combination. It’s a map of momentum more than a verdict on any one technique.

The practical takeaway is orientation: know which advances — AI tools, hybrid imaging, photon-counting CT — are worth tracking for eventual adoption. The resistance, as ever, is departments anchored to legacy equipment and workflows.

We rate the evidence low: by design a narrative roundup of others’ work, valuable for staying current but well below primary research in evidentiary weight, with no conflicts apparent. Its clinical significance is modest and indirect — the technologies surveyed are mostly emerging rather than immediately practice-changing, so the piece informs awareness more than today’s decisions.
