RSI-MRI+ for Prostate
The newest advancement in diffusion MRI
RSI-MRI+ is FDA-cleared advanced imaging software that supports improved prostate cancer detection and diagnosis.
RSI-MRI+ utilizes artificial intelligence and a patented advanced diffusion MRI technique called Restriction Spectrum Imaging (RSI) to increase the visibility of restricted water, a hallmark feature of cancerous tissue.

HOW
RSI-MRI+ Works
The first commercial imaging software to use an advanced multi-compartment diffusion model, RSI-MRI+ better interrogates prostate tissue microstructure to improve conspicuity of restricted diffusion.
Restricted diffusion is a hallmark feature of many aggressive cancers, including prostate cancer, but it’s often accompanied by other sources of water diffusion within the lesion, making it difficult to detect.
RSI-MRI+ provides a unique characterization of the restricted signal component — called the Restricted Signal Map — which improves visualization and quantification of restricted water compared to standard diffusion-weighted imaging (DWI).
