MRI Acquisition
Quality Indicator
Importance Rating
(9,essential)
MRI acquisition protocols should generally follow
PIRADSv2 guidelines
(acr.org) in order to facilitate
diagnostic reporting.
7,7
Replacing coronal and sagittal T2w images with an
isotropic T2w 3D axial acquisition is justified in
radiotherapy planning, especially at 1.5T.
6
When implanted fiducial markers (FMs) or brachytherapy
seeds must be resolved, strategies to augment the FM
signature on above images may suffice (eg. Increase
voxel resolution, PD via dual echo acquisition,
intermediate TE).
7
A separate image may be acquired to more clearly
highlight FMs (e.g. GRE, PD, SSFP, UTE)
