Advanced Myocardial MRI Tissue Characterization Combining Contrast Agent-Free T1-Rho Mapping With Fully Automated Analysis.

ABSTRACT:

Background

Myocardial T1-rho (T1ρ) mapping is a promising method for identifying and quantifying myocardial injuries without contrast agents, but its clinical use is hindered by the lack of dedicated analysis tools.

Purpose

To explore the feasibility of clinically integrated artificial intelligence-driven analysis for efficient and automated myocardial T1ρ mapping.

Study type

Retrospective.

Population

Five hundred seventy-three patients divided into a training (N = 500) and a test set (N = 73) including ischemic and nonischemic cases.

Field strength/sequence

Single-shot bSSFP T1ρ mapping sequence at 1.5 T.

Assessment

The automated process included: left ventricular (LV) wall segmentation, right ventricular insertion point detection and creation of
