3D CSI Prostate Spectroscopy Scanning Workflow
3D CSI Prostate Spectroscopy Scanning Workflow
3D CSI Prostate Spectroscopy Scanning Workflow 1. Prostate Exam Set-up: Patient orientated on table Head > First > Supine Center on two spine coil elements Coils - various coil combinations that can used for a prostate exam: body-array body-matrix coil body 18 (OR) body-array + endo-coil body-matrix coil + endo-coil body 18 + endo-coil 2. Prostate Exam Localization: Acquire a 3 Plane Localizer: Note: Center on Prostate in all three plane 3. T2 TSE High Resolution Sequences: Note: Use T2 TSE High Resolution images to check placement of Endo- rectal coil Acquire T2 TSE Coronal: Angle to long axis of Prostate SIEMENS ww.usa.siemens.com/healthcare Page 1 of 4 306 Effective Date: 09/08/2016 Acquire T2 TSE Axial: Angle to Short axis of Prostate 4. Select > CSI 3D_SE Sequence: VOI large enough to cover prostate gland in all three directions 5. Select > View > Reference Lines: Displays position of one localizer on the other two imaging planes 6. Select > Image segment that displays mid portion of prostate (Axial) for VOI positioning: Right mouse on Axial 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 ww.usa.siemens.com/healthcare Page 2 of 4 7. 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 8. Saturation Band Placement Order: Note: Sat bands should effectively eliminate any lipid contamination wrapping into Spectroscopy data sets Note: Order of Saturation band placement is only necessary if the endorectal coil is used Axial Sat Band Placement: #1 – Posterior to VOI #2 – Posterior Sagittal to Coronal Oblique angled to VOI #3 – Posterior Sagittal to Coronal Oblique angled to VOI Sagittal Sat Band Placement: #4 – Superior to VOI #5 – Inferior to VOI SIEMENS www.usa.siemens.com/healthcare Page 3 of 4 Axial Sat Band Placement: #6 – Anterior Sagittal to Coronal Oblique angled to VOI #7 – Anterior Sagittal to Coronal Oblique angled to VOI Sagittal Sat Band Placement: #8 – Anterior to VOI 9. Exam Task Card > Graphic Slice Display: Note: Manual shimming must be performed for Prostate Spectroscopy CSI 3D examinations 10. Perform Manual Shim for Spectroscopy sequence 11.
