We demonstrate the feasiblity of free-breathing respiratory self-gated thoracic MRI with balanced steady-state free precession half-radial dual-echo imaging technique (bSTAR) in human subjects.
Figure 3. Illustrative
coronal FB bSTAR image reconstructions in a healthy volunteer: using all
acquired data (no gating) - composite (a), data binned to end inspiration -
volume 1 (b), data binned to intermediate respiratory state - volume 5 (c) and data binned to end
expiration - volume 10 (d). For comparison breath-hold bSTAR acquisition was
performed (e).
Figure 4. Comparison
between free-breathing bSTAR composite (a), free-breathing bSTAR expiratory
reconstruction (b), and expiratory breath-hold bSTAR image. Diagram (d) shows
signal amplitude profiles obtained in the region indicated by the yellow box
(signal amplitude was averaged along the x-axis).
