CMR T 1 mapping and strain analysis in idiopathic inflammatory myopathy: evaluation in patients with negative late gadolinium enhancement and preserved ejection fraction

ConclusionsDiffuse interstitial fibrosis can be detected by CMR T1 mapping in patients with IIM who do not have LGE or reduced LVEF or elevated hs-cTnI, and it may be a promising method for screening subclinical cardiac involvement in IIM.Key Points• Myocardial abnormality in IIM is often subclinical and leads to poor prognosis.• Conventional CMR parameters have limitations in early detection of cardiac function and tissue changes.•CMR T1mapping techniques and myocardial strain analysis have the potential to provide detailed information on cardiac histology and function.
