MRI Acquisition
Quality Indicator
Importance Rating
(9,essential)
DWI is recommended to assist in depiction of tumours if
needed.
9
DCE is considered optional except for salvage of
recurrence.
7
Activation of vendor-provided gradient distortion
correction and optimization of bandwidth (fat/water pixel
shift <1mm) is recommended to maintain geometric
fidelity.
8
DWI should follow the QIBA profile (
qibawiki.rsna.org).
Distortion can be minimized using i) R-L phase-encode
direction, ii) volume shimming over the gland, iii)
minimizing effective echo-spacing, and iv) considering
segmented or other non-EPI techniques.
8.5
Motion-related artefacts should be mitigated by limiting
acquisition time to < 5 minutes when possible.
Sequences should be repeated if motion-related artifacts.
