MR View&GO - TimeCurve (Numaris X - XA60)

MR View&GO – TimeCurve Numaris X Job Aid syngo MAGNETOM MR Systems with Numaris X software TimeCurve evaluates dynamic data sets to show a change in signal over time. The output of such an evaluation is a time curve that plots the intensity of the contrast media over a certain time pe- riod. TimeCurve evaluates the signal intensity over time of the Test Bolus within an ROI located in a larger vessel in the target region. The resulting signal curve gives patient-specific and region- specific information about the transit time of the contrast agent. Disclaimer: A licensed physician may choose to use FDA-approved contrast agents in conjunction with an MRI exam, based on his/her medical opinion and discretion and in accordance with the instructions for use and indications for use supplied by the pharmaceutical manufacturer for the contrast agents. 1. Load the Test Bolus images into MR View&GO. 2. Select the Test Bolus image segment to perform TimeCurve postprocessing. 3. In the Favorite Tools area, click on the TimeCurve icon.

In the TimeCurve Layout, the Dynamic Series loads into the first segment. 6. Select the Dynamic series, press the right mouse button, and move left/right to page through the images to find the vessel of interest.

Click on the TC-Circle icon and draw a circular ROI inside the vessel. The ROI is applied to all images having the same orientation within the same segment. Each ROI is a distinct color. The corresponding result curve is displayed in the same color.
