2D Perfusion Perfusion imaging in angiographic interventions

High-definition visualizations


Being able to precisely follow the uptake of contrast in blood vessels when re-vascularizing or Embolizing an artery is critical when assessing the effectiveness of an interventional procedure. Our 2D Perfusion software is an interventional tool, which visualizes the flow of contrast through vessels and the organ parenchymal enhancement over time, in a colored 2D image.. These high-definition visualizations are based on DSA (digital subtraction angiography) acquisition protocols dedicated per anatomical region, which show blood vessels and parenchymal enhancement with a high degree of specificity.

Instant perfusion feedback during procedures


2D Perfusion requires only one contrast media injection and one DSA run, to obtain rich information of vessel and organ perfusion in the interventional suite. By comparing pre and post procedural images, clinicians can easily identify perfusion differences in the color images. This allows the clinician to verify if the required level of perfusion has been achieved.



Visualize perfusion changes of brain parenchyma after carotid artery stenting or cloth removal in case of ischemic stroke. Analyze perfusion behavior of brain tumors and arteriovenous malformations (AVMs).



Monitor the perfusion behaviors of feeding vessels and tumors before and after embolization to evaluate blood flow changes and define procedural endpoints.

Peripheral radiology interventions


Visualize hypo perfusion in peripheral artery disease and monitor effects of revascularization in real time.

Comprehensive data analysis tools


Clinicians can draw a region of interest and analyze the time density curve to quickly obtain comprehensive quantitative data for decision making. Conventional perfusion parameters are measured including mean transit time, arrival time, time to peak, wash-in rate, width and area under curve.
