4D Flow


What is 4D Flow?

4D Flow is a specialized MRI sequence that enables high speed acquisition of time resolved anatomy and, for the first time, blood flow data in the human body. With advanced cloud processing capabilities, this data can now be used for routine clinical cardiovascular diagnosis.

Acquisition Workflow


What MRI pulse sequence do I need?

To acquire 4D Flow data, you need to ensure that you have the 4D Flow sequence enabled on your MRI. As we are vendor agnostic, contact us to help you find a solution.

What scanning parameters should I use?

We provide an optimized set of parameters so that any imaging technologist can perform the acquisition.

Do I need to use a contrast agent?

For best results on cardiac scans, the use of a blood pool agent is recommended to obtain improved signal to noise ratio on moving organs.

What type of coils do I need?

32-channel coils are recommended for 4D Flow cardiac acquisitions, but 8-channel or 16-channel coils can also be used.

Which MRI vendors are currently selling a 4D Flow pulse sequence?

The sequence is available to research sites by all major vendors.

Upload workflow


How long does it take before I can view images?

On completion of the scan, you can view and process images in under 10 minutes, though this is dependent on the bandwidth available and file size. The majority of this time is spent uploading images.

Do I upload images manually or does this happen automatically?

Most sites prefer to have their data pushed automatically to the Arterys™ Cloud; please contact us if you would like to enable this feature. Manual upload of images is always available through your browser.

Processing workflow


Do I need to download software to view, process and create a clinical report?

No. The Arterys™ interface is accessible via the Google Chrome web browser (we support the latest versions). No software plugin is needed.

What kind of training do I need?

The interface is intuitive and within 10 minutes you can feel comfortable with simple quantification. We will provide you with hands on screen sharing support if you need it, in addition to video tutorials that walk you through the interface.

How do I create a clinical report?

You can create a clinical report that can be exported as PDF or DICOM that gets seamlessly pushed to your PACS (including secondary captures) all within your web browser interface. Your clinical report includes your comments in addition to the views, videos, annotations and measurements you previously created.

How do you push images automatically back and forth between the scanner, PACS, and the Arterys™ Cloud?

We will provide you with a tiny software program that runs either on your scanner workstation or external workstation that acts as the private gateway between all image sources (Windows, Linux, and Mac compatible).

How do I share a study with other users or hospitals?

Using the web browser interface, any study and workspace can be shared privately with any collaborator around the world instantly via a simple secured link.

Clinical Applications


How long does a cardiac study take?

One of the key benefits of 4D Flow is the speed at which quality acquisitions may be performed. A 10 minute scan yields cardiac flow and function (replaces all 2D-PC and SSFP short and long axis sequences). A 20 minute scan provides full tissue characterization, including scarring.

Security & Regulatory


Is this product regulatory approved?

Yes, the Arterys 4D flow post-processing for visualization and quantification for cardiac MR images has FDA 510(k) clearance in the United States, and a CE Mark for Europe. Global regulatory expansion coming soon.

Are you HIPAA Compliant?

We are fully HIPAA compliant and will work with any local regulations to keep patient data private and secured.

My hospital doesn't feel comfortable sending patient data to the cloud, is there a solution?

If required, data can be de-identified / anonymized prior to leaving your hospital network.
