MR CSI Scanning Workflow - Numaris X Job Aid

MR CSI Scanning Workflow Numaris X Job Aid MR Multi-Voxel Spectroscopy (CSI) Scanning workflow - Numaris X Job Aid 1. Images acquired in all 3 planes are used to position the voxel (VOI). a. Routine sequences (e.g., T1,T2, etc.) are used to position the voxel. (i.e., localizers can be used to position the voxel, but routine sequences have better image quality) b. Acquire series with Full Brain coverage in all three (3) planes. c. Table Positioning Strategy is Local Range. d. Hint: series can be acquired orthogonal, oblique, or double oblique. 2. Click on the myExam Cockpit icon to open myExam Cockpit. a. Choose any Multi-Voxel Spectroscopy (CSI) sequence.

To Position the CSI multi-voxel. a. When the sequence is opened and ready to be planned, a Spectroscopy Guidance window is displayed. The step-by-step guidance is used throughout the planning process. b. Hint: make sure the voxel is not placed in Bone, Air, or Fluid. This can be challenging depending on the location of the lesion.
