Evaluation Options Step – optimize Evaluation Results a. VENC Anti-Aliasing Icon – if measured maximum Flow Velocity is lower than the Ac- tual Flow Velocity, there will be signal void areas in the vessel due to aliasing b. Select VENC Anti-Aliasing Icon – images are updated • Aliased pixel values are corrected, and results are updated c. Adjust Background Phase – Move Threshold slides to adapt the stationary tissue d. Select Auto Button – restores default stationary tissue mask (e.g., select only if neces- sary) e. Select Exclude Regions Icon – draw a contour around regions that shouldn’t be in- cluded into the stationary tissue mask f. Delete Exclusion Regions Icon – select if you want to delete and redraw the exclusion region (e.g., select only if necessary) g. Select Apply – corrects the pixels for the phase contrast 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: 11/29/2021 | HOOD05162003238062 Healthineers Page 3 of 5 Job Aid | MR Cardiac Flow – Numaris X Effective Date: 11/29/2021 | HOOD05162003238062 7.
