Why the study?
Does a frame rate of 50-60 Hz allow accurate two-dimensional speckle-tracking strain measurement in silico-simulated models and patient images?
Does a frame rate of 50-60 Hz allow accurate two-dimensional speckle-tracking strain measurement in silico-simulated models and patient images?
A frame rate of 50-60 Hz, combined with correct region of interest definition and noise reduction, is sufficient for accurate 2D speckle-tracking strain measurements.
Answers are grounded in this paper and cite their sources.
Supports standard 50-60 Hz settings for routine 2D strain assessment; extends validation from simulations to patient images.
Standard machine settings with a FR of 50-60 Hz allow correct assessment of peak global longitudinal and circumferential strain. Correct definition of the region of interest within the myocardium as well as the reduction of noise and artefacts seem to be of highest importance for accurate 2D strain estimation.
