AI-powered for safer MRI*

At Subtle Medical, we’re dedicated to developing innovative healthcare solutions that put patient safety and wellbeing first. SubtleGAD™ (currently in investigational stage) is a software that uses state of the art deep learning technology to enable a 90% dose reduction of GBCA’s for contrast-enhanced MRI while maintaining excellent image quality.

SubtleGAD™ is being developed to provide a potentially safer option for patients who need to undergo MRI exams by reducing the necessary gadolinium dose by up to 1/10th of the standard dose. The software infrastructure is being built to seamlessly integrate between any brand of MR scanner and PACS.

Subtle Medical was awarded a $1.6 Million SBIR Grant in 2019 to conduct research on SubtleGAD™. In 2020, Phase II funding was awarded based on the results achieved during Phase I, as well as the scientific and technical merit of the project.
