Is manual measurement of global longitudinal strain from mid-myocardial lengths (MM-GLS) a reliable alternative to speckle tracking global longitudinal strain (ST-GLS)?
Manual measurement of global longitudinal strain from mid-myocardial lengths is a reliable alternative when speckle tracking cannot be accurately assessed.
MM-GLS correlates strongly with ST-GLS. If ST-GLS cannot be accurately assessed, MM-GLS may be a useful alternative to provide GLS values in both clinical and research studies.
