Multi Voxel Spectroscopy Scanning Workflow (Numaris X) Step by Step

Multi Voxel Spectroscopy (CSI) Scanning Workflow (Numaris X) syngo MR Systems with Numaris X 1. Images acquired in all 3 planes-used to position voxel(VOI) A. Acquired orthogonal, oblique or double oblique B. Localizer images (full brain) all planes can be used. Routine sequences (ie: T1,T2,etc.) are best to use for positioning the voxel C. Full brain coverage in all 3 planes 2. Sequence: For multi voxel spectroscopy choose any csi sequence Csi_se_30 07:12 9 Spectroscopy esi_se_135 07:12 Spectroscopy csi se 270 07:12 O Spectroscopy csi3d_se_135 07.53 0 Spectroscopy csl_st_20 07:12 O Spectroscopy csi_st_135 07:17 Spectroscopy csi_st_270 07:24 Spectroscopy 3. Positioning of the Voxel A. With spectroscopy the main goal is make sure the the Voxels are not in Bone, Air or Fluid. This may be hard depending on the location of the lesion. B. When the scan is opened to be planned, a guidance window will pop up Brain Dot Engine ---. + HAL 1 % csi_slager_135 9020.03 20-14:18: 54-STD-1.3.12.2 1107 5.993 2020 03 26-14: 18:54-STO-1 3.122.1107 5.993 2020 00:26-14:16:56-9TD-1 3.12 2.1107 5.993 10 MA 1 FRV 66/192 JIMA 1 FRM 3/03 11 MA 1 FRM 14/27 RPM A TP O TP O TPO SP R10 2 SP PO.8 SP H24 FOX 240-240 FOV 259-250 Fev 220-220 (3).Tra(1) Cor-Sig(-4).Try(-1) Tra-Con(-10) .Sag(-1) 00:00 AMMM_SCOR_MPR_cor Cancel 3 6.53 min & Manual @ 10.0-10.0-15.0 mm 1.00 Spectroscopy Parameters Spectroscopy steps can only be planned on non-distortion corrected images Please do the following steps for examination planning drag all series needed for planning into GSP prenelect the region of spectroscopy examination by placing a ROI on one series press "Convert images" so generale non-dalortion corrected images for planning the converted images will be automatically loaded into the GSP plan your spectroscopy examination FROMtheprocessuale some pontos and round size, place une "Copy Parameter' atch Convert images Unrestricted 0 Published by Siemens Healthcare GmbH © Siemens Healthcare GmbH, 2020 SIEMENS Master Template Effective Date: 3/5/2020 | HOOD05162003074494 Job Aid Effective Date: XX/XX/XXXX | HOOD/HILS Healthineers Job Aid | Multi Voxel Spectroscopy Scanning Workflow (Numaris X) Effective Date: 05/11/2020 | HOOD 05162003087238 C.

At the bottom of the step by step guidance, the Convert Images button will now be active. Click on it and the scans will be converted to Non Distorted images that are need to plan the spectroscopy. Convert images D. Now the multi voxel will show up in the images that were selected. i. The white area is the area of the voxel and it surrounded by 4 sat bands. These sat bands can be moved to cover up bone, air or fluid to clean up the spectrum. ii. VOI can be changed and also the FOV can be changed to prevent wrap if the volume is not exactly centered HAL HAR AHR test test A 2020.03.26-14:18 64/8TO-1.3.12.2.1107.5.99.3 2020.03.26-14:18:54-STD-1.3.12 2.1107 5 99 2020.03 26- 14:18.54-STD-1.3.12.2.1107 5 99.3/ 14 IMA 1 FRM 64/192 16 JMA1.FRM 86/160 IM.A.L.FRM 14/27 FoVR >> L 160 - mm FoVA>> P 160 - mm Thickness F >> H 15 - mm ARF RPF Sem Vol R >> L 80 - mm Vol A >> P mm A SP P15.1 FOV 2407240 FOV 230*230 (Co-S3g(-3)>Tra(-1) 220 220 Sto Cor(3)-Tra(1) ...
