• HealthLytix obtains FDA approval for prostate imaging software

    The approval leverages an advanced diffusion MRI technique known as Restriction Spectrum Imaging (RSI). It allows clinicians to detect and diagnose prostate cancer at an early stage.

    Claimed to be the first FDA-approved imaging software, RSI-MRI+ uses artificial intelligence (AI) and a tissue microstructure model to enhance the visibility of reduced water in the body’s tissue.

    Reduced water is a hallmark feature of several cancerous tissues. The traditional diffusion-weighted imaging applies apparent diffusion coefficient (ADC) to calculate the limited water in the body’s tissue.

    Various confounding factors pose a negative influence on ADC’s sensitivity and specificity to cancer, leading to missed or inaccurate diagnosis.

    Contrary to the conventional diffusion-weighted imaging (DWI), HealthLytix’s RSI-MRI+ imaging software characterises the restricted signal component, Restricted Signal Map, to provide improved visualisation and quantification of reduced water.

    HealthLytix CEO Nathan White said: “A key innovation of RSI-MRI+ is that it can better characterise the complexity of water diffusion in cancerous tissue, resulting in better performance. With early-stage aggressive cancer, we need more sophisticated approaches to separate what’s important from what’s not important.
