FAQs

General Questions

|

Please contact Radius@rad.wisc.edu to get connected directly with one of our team members

Information that is helpful for Radius to know includes: project title, project PI, IRB number (if applicable), a brief description of the project, what analyses or data you want Radius to provide, project timeline, project funding and study personnel contact information.

Typically, there is a 1-week turnaround time for prospective imaging. There are many factors that can affect this such as the number of analyses requested per scan, complexity of the patient’s anatomy, and other study needs. This can be negotiated at the time we generate a budget for the study analyses expected.

Yes.

Yes.

Yes.

Based on the results of an initial consultation, we may offer opportunities for custom analyses, new method development, and/or pilot analysis.

Compliance, Security, and Data Handling

|

21 CFR Part 11 and HIPAA.

Please contact Radius@rad.wisc.edu to get connected directly with one of our image analysts to discuss your existing imaging and determine what transfer method is most appropriate.

Yes! We take great care in de-identifying images according to all applicable institutional, state, and federal compliance standards. Please note: Radius is only able to de-identify imaging for research studies and educational purposes.

Radius uses only UW approved tools for data transfers of PHI or limited datasets. Research Image Requests are only viewable by Radius staff and saved to a secure network drive in the Radiology department.

Radius has worked with the following for internal data: Flywheel, Globus, PACS, Research PACS, RedCap, Box, Sharepoint, Teams, Healthlink and more. Which method is used depends on what type of data is being transferred and who the intended recipient is.

Yes.

Dicom format is the preferred format for the image data Radius works with. If the data is in a different format, please contact Radius at Radius@rad.wisc.edu to see if we are able to handle your request.

Researcher-Focused FAQs

|

Yes. We ask that you include Radius in supporting sections of your applications and/or manuscripts.

If the analysis of medical images are part of a clinical trial/research study, we are
unable to enter results into and study specific REDCap/EDC or Healthlink as the
methods or software may not be approved for clinical use. Please contact Radius
at Radius@rad.wisc.edu to discuss your study’s needs.

Please complete a research image request form here.

Radius partners with CRDS/SMPH Informatics to generate a patient cohort and specific exams which meet your criteria. Please start by completing a Data Request consult here. Make sure to specify “Radiologic Images from UW Health Clinical Systems” in the request.

Radius is unable to provide this data directly. We partner with CRDS/SMPH Informatics who has access to pull this information from PACS or Healthlink. Please start by completing a Data Request consult here.

Clinician-Focused FAQs

|

Yes.

This pipeline is currently being built.

Industry-Focused FAQs

|

Yes.

Yes, although scaling will require involved planning and communication with the
organization. It may also require a multi-phased process over a long period of
time. Consultation required.

Service-Specific FAQs

Abdominal Services

|

AMRA services provided through Radius are available only to UW researchers at this time.

Cardiac & Cardiovascular Services

|

Yes.

3D Modeling Services

|

Yes, we offer 3D printing for both of these applications, in addition to research.

We use a cloud-based system called Mimics Viewer to present the final 3D model in virtual format. This interactive viewing tool can be used to verify, iterate, and analyze the virtual model.

Some 3D models are printed using a plastic or resin, in which case we deliver both a virtual version through Mimics Viewer as well as a physical model.

In the case of clinical applications, we send a rotating image of the 3D model to PACS as a record (there is currently no associated dictation).

For clinical use, an order can be placed in HealthLink using the procedure code R0559T. We will contact the ordering physician by email for a brief consultation to fully understand what is needed.

For educational or research applications, please contact us for a consultation.

Tumor Response Services

|

Yes.

Yes.

At this time, our mint Lesion software is not licensed for commercial use. However, there is an option to convert to a commercial license and we would be willing to consider depending on the project needs. Please contact Radius at Radius@rad.wisc.edu to schedule a consultation.

De-Identification & Coding Services

De-identification and coding requests can be submitted directly through our
online form.
