Abstract

Background Left ventricular myocardial motion analysis and the assessment of regional dysfunction are crucial for the detection and prognosis in different cardiac pathologies. Myocardial tagging (MT) is a cardiac magnetic resonance (CMR) based method for tracking myocardial motion, which has been established as reference standard for assessment of strain. Currently, strain can also be assessed by CMR using feature tracking (FT) or by echocardiography with speckle tracking (ST). Aim of our study was to evaluate intraindividually and compare myocardial circumferential strain (Ecc) using MT, FT and ST.

Highlights

Left ventricular myocardial motion analysis and the assessment of regional dysfunction are crucial for the detection and prognosis in different cardiac pathologies
In 34 patients (204 segments) global strain values for all techniques were available (MT: -20.6 ± 3.4%, feature tracking (FT): -22.6 ± 5.6%, speckle tracking (ST) -10.1 ± 2.9%) and showed a moderate agreement between Myocardial tagging (MT) and FT (Figure 1), while no reasonable agreement was observed between FT and ST and MT and ST
The segment based analysis (Figure 2) revealed a poor agreement between FT and tagging for all segments, while no agreement was observed for ST and FT, as well as for ST and FT
