MR View&GO TimeCurve - Numaris XA31

This Job Aid reviews how to use TimeCurve to evaluate dynamic data sets and signal changes over time.

MR View&GO – TimeCurve Job Aid syngo MR Systems with Numaris X TimeCurve can be used to evaluate dynamic data sets to show signal changes over time. The output of such an evaluation is a time curve that plots the intensity of the contrast media over a certain time-period. TimeCurve can be used for test bolus scanning or lesion evaluation in dynamic scans. All dynamic series must be run in one sequence to use the TimeCurve.  Note: Image data must be classified as 4D to be able to load into TimeCurve 1.
