Ambra FAQ

In addition to the frequently asked questions below, please look at our Ambra User Guide

I don’t have access to the Ambra system. How do I get access to the Ambra System?

Please submit a ticket to the RDCRN DMCC support desk with the following information:

• User name / RDCRN ID

• RDCRN/Consortium protocol number

• For each group/location:

  • Name of group (e.g. which clinical site, radiologists)

  • role (e.g. radiologist, PM, CRC)

We will need to get sign-off from the protocol CRC/PI before granting access.

The image upload seems slow, what should I do?

Please check the Ambra status page to see whether there is an issue with Ambra itself.

There are many factors that can affect image upload including the size of the imaging study, internet connection speeds, internal network speeds if the images are on a shared drive, etc. The first step would be to use the Ambra Speed Tester to check the connection speed with Ambra. Additional information on slow uploads can be found on this Ambra Support Page: Troubleshooting slow uploads.

I uploaded a study, but when I view it, I get an error message that says “No Images Found”

The most common reason for this error is that on upload, the DICOM images (.dcm) were wrapped.

On the upload studies screen, there might be a checkbox that says “Select files for DICOM wrapping”. This checkbox should only be used if the files being uploaded are not DICOM files. Examples of these would be photos (i.e. jpg, png), videos (i.e. mp4), or other formats (i.e. pdf, stl).

Open

When uploading DICOM file, only the folder that contains the DICOM file(s) needs to be selected. All subfolders will then be scanned for DICOM files and a table will display with the studies found and some basic metadata such as number of images, Patient Name, and Study Date.

I uploaded a study, but I cannot find it in Ambra.

If you have recently uploaded the study, check the “Activities” queue. All imaging studies uploaded to Ambra require approval within Ambra.

If you cannot find the study in the “Activities” queue, it is possible that the study has been previously uploaded and approved, that the upload failed or something else happened. It is also possible that the study has not fully processed in the system. Depending on the size of the study, it can take up to 30 minutes to appear in the queue.

To see if the study has been previously uploaded:

• Check the name space in which the image was uploaded to search for the imaging study.

• If you find the study, view the images to ensure the images are properly de-identified.

  • If the images are not de-identified, Request Study Deletion. The study will need re-uploaded after the current study has been deleted. NOTE: If you upload prior to the current study being deleted, the same issue will occur.

If you are still unable to find the study, please contact the RDCRN DMCC Service Desk and include the following information:

• Name of the clinical site (e.g. DMCC - 1000 Cincinnati Children’s Hospital)

• Local ID and/or Participant ID

• When you believe the imaging study was uploaded

I cannot find a study in the Radiology or Protocol Groups.

If the study was recently uploaded and approved, you might need to wait for the Ambra system to fully share the image to these groups. The bigger the imaging study, the longer it will take. Typically it should appear within 15-20 minutes.

If the study does not appear after 24 hours, please contact the RDCRN DMCC Service Desk and include the following:

• Name of the group where the study is missing (e.g. DMCC - 1000 Radiologist)

• Local ID and/or Participant ID

• Dataset Name (e.g. Brian MRI)

• Visit Name (e.g. Baseline, 1 year)

I uploaded the wrong study and need to delete it.

If the study is still in the Activities Queue, click the “Reject” button, enter a reason, and then click Reject.

If the study has already been approved, use the instructions listed in the Features and Workflows Documentation to request study deletion as well as to confirm the deletion.

My Study has the wrong date.

If an imaging study has the wrong study date, you need to click the “Edit” button for the study, change the data (format is MM-DD-YYYY), and then click “Save”
