So what is NeoVista®?
NeoVista® combines all of the individual ideal imaging components into a single comprehensive test. The full NeoVista® examination includes:
Most MRI imaging centers can perform single components from this list. For example, some imaging centers will perform an MRA (MR angiogram) of the subclavian arteries to diagnose TOS.
MRA of bilateral subclavian arteries
Now, this image demonstrates two important details. First, the image shows both subclavian arteries with good detail. Most imaging centers using standard injected gadolinium contrast material will achieve good quality on one side only. For example, Raptis, Thompson, et al published in 2016 that, “The intravenous catheter should be placed on the side opposite the symptoms…”. They and other centers can only consistently achieve good imaging quality on one side, and must avoid the symptomatic side. But what do they do if the patient has bilateral symptoms? The NeoVista® examination overcomes this limitation. One injection, one set of images, excellent quality.
Second, not only are the arteries bright, all other tissues are darkened as much as possible. While this is fine for evaluating the arteries, there is no way to tell if extrinsic structures are compressing the arteries. Since TOS is caused by extrinsic structures in the thoracic outlet, this is a a significant limitation. The NeoVista® examination acquires all essential imaging components in one comprehensive study. Thus, the radiologist can match abnormal arteries with abnormal extrinsic structures seen on other images.
Some imaging centers will perform isolated images of the brachial plexus, sometimes referred to as an MR neurogram.
Bilateral Brachial Plexus
Again, you can see the brachial plexus is bright, and the background is dark. So, it is almost impossible to know if a structure is compressing or stretching the brachial plexus. NeoVista® overcomes this limitation.
It is important to remember that none of these individual imaging components can tell the story by itself. TOS is complex and multi-factorial, and multiple imaging components are necessary to tell the entire story.
And that is exactly what NeoVista® achieves. The NeoVista® examination includes every one of these components in a single comprehensive study, taking only 45 minutes. The US Patent and Trademark Office has awarded three patents to date for this unique technology.
