Dark blood T2-weighted imaging of the human heart with AI-assisted compressed sensing: a patient cohort study.

Background: Dark blood T2-weighted (DB-T2W) imaging is widely used to evaluate myocardial edema in myocarditis and inflammatory cardiomyopathy. However, this technique is sensitive to arrhythmia, tachycardia, and cardiac and respiratory motion due to the long scan time with multiple breath-holds. The application of artificial intelligence (AI)-assisted compressed sensing (ACS) has facilitated significant progress in accelerating medical imaging.

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

Objectives: To investigate whether cardiovascular magnetic resonance (CMR) T mapping and strain parameters can detect early histological and functional myocardial changes in idiopathic inflammatory myopathy (IIM) with negative late gadolinium enhancement (LGE) and preserved ejection fraction.

Methods: Thirty consecutive patients with IIM (41.5 ± 15.

MRI native T1 and T2 mapping of myocardial segments in hypertrophic cardiomyopathy: tissue remodeling manifested prior to structure changes.

Objective: The aim of this study was to examine the local myocardial segments in hypertrophic cardiomyopathy (HCM) by MRI T1 and T2 mapping, and to investigate how tissue remodeling correlates with structural and functional remodeling in HCM.

Methods: 47 patients with HCM and 19 healthy volunteers were enrolled in this study. All subjects underwent cardiac MRI at 3.
