Prescribe and scan a pulse sequence

About this task

Keep the following important points in mind when using PURE or other image filter options with scans that are post processed or displayed in a viewer.
  • The PURE feature changes the pixel intensity in the image to provide a more uniform image. For example, when cardiac protocols are used in conjunction with PURE for dynamic MRI time-course imaging, delayed enhancement, StarMap and phase contrast imaging, a modification to the AW applications of ReportCARD*, Flow Analysis, StarMap or AngioCARD difference threshold may be required. We recommend disabling PURE for all phase contrast acquisition. It is recommended to either disable PURE for dynamic time-course, delayed enhancement, StarMap studies or apply the PURE feature uniformly across all the series.
  • The output of post processing can be modified with any change to the protocol. For optimal image quality, keep consistency with protocols and use the same type of filter or apply PURE for both pre and post contrast imaging.
  • If using the ReportCARD, Flow Analysis, StarMap or AngioCARD post processing software, refer to the operator manual regarding any change to your imaging protocol and the use of PURE or other image filtering techniques.

Use these steps to prescribe and scan a pulse sequence.

Step-by-step instructions

  1. Start a scan session.
  2. Acquire a 3-Plane localizer.
  3. If any or all of these scan parameters are selected (ASSET, HyperBand, PURE), and if you select On from the Calibration in Prescan menu, which is located on the Details tab, a calibration scan is acquired during Auto Prescan.
  4. From the Workflow Manager control panel screen, click Add Task > Add Sequence.
  5. From the Protocol screen, select a protocol from your site or GE library. Click Accept to close the Protocol screen.
    If you cannot locate the desired protocol in either library, then from the Protocol screen:
    1. Click the Template tab.
    2. From the list, select the desired family folder.
    3. Select the desired PSD.
    4. Click Accept.
  6. From the Workflow Manager, select the series.
  7. From the Scan/Task controls panel, click Setup.
  8. Make scan parameter adjustments as needed.
  9. Graphically deposit and position slices or a slab(s).
  10. When the prescription is finished, click Save Rx > Scan.
