MAVRIC diffusion weighted imaging can image tissue microstructure in
peri-prosthetic regions with strong magnetic susceptibility effects. This work
compares the accuracy of DWI-MAVRIC relative to conventional echo
planar-imaging-based DWI.
Figure 1: (A) Coronal DWI-EPI (NEX = 1) and (B)
Coronal DWI-MAVRIC (bins=3) images of 13 PVP vials contained in phantom. (A)DWI-EPI
contains low EPI distortion while (B) DWI-MAVRIC contains no EPI distortion.
Figure 2: ADC mean values for eight acquired scans (six coronal, two
axial) at all six polymer concentrations. The dashed lines show the references
values from Palacios et al.(10) for all
six concentrations.
