Comprehensive review of artifacts in cardiac MRI and their mitigation

This is a technical review aimed at the people running and reading cardiac MRIs, and its subject is unglamorous but consequential: the artifacts that degrade images and can lead to misdiagnosis.

The authors catalog the full range of cardiac MRI artifacts — motion, flow, metal, and the rest — and pair each with up-to-date strategies to prevent or correct it. The premise is simple: a scan is only as good as its image quality, and recognizing an artifact for what it is prevents both false findings and missed ones.

The practical takeaway is craft knowledge: technologists and radiologists who know these artifacts and their fixes produce more trustworthy reads. There’s little controversy here, beyond the cost of updating legacy hardware and habits.

We rate the evidence low: a conflict-free, 75-reference technical review summarizing known artifacts and mitigations, without primary validation. Its clinical significance is low for direct patient care — it improves imaging quality rather than guiding treatment — but it’s genuinely useful to the imaging specialists whose accuracy depends on getting these details right.
