MR LiverLab - E-line Job Aid

This Job Aid provides workflow steps for an abdominal examination using the MR LiverLab Dot Engine on an MAGNETOM MR System with E-line software.

MR LiverLab: E-line Job Aid syngo MR Systems with DotGO Technology MR LiverLab can be found within the Siemens Tree, Abdomen Dot Engine protocols. The customer can incorporate their own routine liver sequences into the LiverLab protocols within the Abdomen Dot Engine.
