Synopsis

In this work, we investigated the influence of fat in the estimation of strain from tagged MR images. The results showed that in a static phantom with sharp and smooth fat fractions, the estimated strain is influenced by the bandwidth of the bandpass filter, the tagging period, and the fat fraction.
