In-room imaging and MR planning

MR-Simulator

Requirement

Recommendation/Comment

System

1.5 T or 3.0 T wide bore (70 cm) scanner

Set-up

Flat table & immobilisation; utilise high channel RF coil arrays & intensity correction

Distortion

3D gradient correction; measure residual. High BW; Optimise shim where needed; B0 mapping still not widely available

Protocol

2D TSE & DIXON (±C) primary planning sequences; 3D important in specific cases (e.g. T2 MR-only, T1 SRS) Functional & motion assessment not standard

Resolution/ coverage

maximum 1mm or 1 pixel fat-water shift

2-3/0 mm slices (2D) standard; 4 mm functional (e.g. DWI) Single concatenation 3D isotropic as required

30 cm scan coverage
