VasSol’s NOVA (Non-invasive Optimal Vessel Analysis) is the first and only product line to non-invasively quantify the volumetric blood flow rate in vessels of the brain.

NOVA incorporates interactive 3D images that provide a fully rotatable, 360° view of vasculature that allows for precise identification of each vessel

for volumetric blood flow calculation. NOVA provides physicians with the flexibility to evaluate entire vasculatures or pinpoint specific areas within a vessel that may be of concern.

VasSol’s first application, the NOVA Neuro system, focuses on the neurovascular region, which encompasses the head and neck. Specifically, the data gathered in the NOVA Neuro system has proven to be highly beneficial in diagnosing and treating individuals who are at risk for or who have suffered from stroke and cerebral aneurysms, as well as those who suffer from neurovascular disease related to chronic medical conditions such as heart

disease and diabetes.

NOVA is easily incorporated into your MRI services. A NOVA PC is linked to the MR host system and processes the data from a standard MRA study.

NOVA uses traditional time-of-flight (TOF MRA) and phase contrast magnetic resonance imaging (PCMR) to visualize the anatomy and quantify blood flow.

The NOVA PC is linked to the MR Host System. Additional networked PCs are available for the radiologist and referring physician to review the results.


What information is included in the NOVA Report?

Flow Map: Schematic diagram of circulation annotated with the flow measured in each vessel
3D/4D: surface rendering of vascular anatomy
Flow Summary: list of vessels studied, flow rates and reference values
Waveforms: pulsatile flow and velocity in a cardiac cycle

The NOVA 3D model rotates a full 360°, allowing the anatomy to be viewed from all angles. (Note: To view the content properly, please make sure pop-up window will not be blocked by your web browser)


The NOVA report shows volumetric flow rates, velocity, waveforms and flow direction.

Pre-Endarterectomy, NOVA quantifies the reduction in right internal carotid flow and establishes a baseline for this patient.


Compare pre and post intervention to assess the effectiveness of treatment

NOVA documents the quantitative improvement in right internal carotid artery flow after endarterectomy. Note the collateral supply from the right posterior artery before endarterectomy. After endarterectomy, right middle cerebral artery flow has improved and there is a corresponding decrease in the compensatory flow from the posterior circulation.
