Implication

Randomized trial validates cine MR imaging measurements of deformation in a silicone phantom, indicating accuracy for future motion estimation techniques.

Key Points

The aim is to validate cine magnetic resonance imaging tagging measurements for a deforming object using photography.
Cyclic stretching of a silicone rubber phantom inside a plastic clamp driven by a respirator pump.
Deformation measured using a rapid gradient-echo cine tagging sequence and stroboscopic photographs over a 7-cm region.
Analysis of standard error between MR imaging and photographic data.
Cine MR imaging showed a maximum standard error of +/- 0.002 compared to photography's maximum standard error of +/- 0.001.
The MR imaging deformation estimates closely matched the photographic deformation versus time data.
Validated tagging methods can enhance MR imaging motion estimation techniques.
