Multi Voxel Spectroscopy 2D & 3D (CSI) Scanning Workflow

Multi Voxel Spectroscopy 2D & 3D (CSI) Scanning Workflow

Multi Voxel Spectroscopy 2D & 3D (CSI) Scanning Workflow 1. Scout images acquired in all 3 planes – used to position voxel (VOI)  Acquired orthogonal, oblique or double oblique Scout images or routine images (i.e., T1, T2, etc) can be used for  positioning voxel  Full brain coverage in all 3 planes Note: Distortion Correction should not be used for any sequences in  a Spectroscopy protocol 2. Open > CSI pulse sequence in Exam Task Card Queue 3. Select > View > Reference Lines Displays position of localizers on the other two imaging planes  4. Select > segment with reference image for VOI positioning (typically an axial image is used) Right mouse on Reference image  Select > Copy Image Position  Note: CSI sequence must be open in imaging queue  Note: Positions VOI in the same orientation and table position  as the reference image SIEMENS www.usa.siemens.com/healthcare Page 1 of 2 304 Effective Date: 09/08/2016 5. Position voxel over area of interest Select > Scroll > Nearest  Note: Finds intersecting planes of all 3 localizers or routine images   Note: voxel can be square, rectangle, and angled Ensure Voxel is a “Solid box”  Solid Box – indicates the voxel has intersection in all 3 imaging  planes Dotted Box – indicates displayed voxel is in front of or behind  selected imaging plane Note: This workflow uses automated shimming  6. Select > Apply  Note: runs pulse sequence SIEMENS www.usa.siemens.com/healthcare Page 2 of 2
