Morgan Stanley Investment Management announced today that funds managed by Morgan Stanley Expansion Capital have led a $33 million growth financing for Subtle Medical (the Company), a medical imaging software company using artificial intelligence to improve imaging workflow efficiency and image quality across MRI, PET and CT. The financing included participation from Shinhan Venture Investment and existing investors Fusion Fund, EnvisionX, BRV, and Samsung Ventures, bringing Subtle Medical's total capital raised to $86 million.
Based in Menlo Park, CA, Subtle Medical develops vendor-neutral software designed to operate across existing imaging equipment, regardless of manufacturer. Its solutions are used by hospitals and imaging centers to support scan-time reduction, image enhancement, dose optimization and imaging standardization workflows without requiring immediate replacement of existing scanner infrastructure.
"Medical imaging is a critical component of healthcare delivery and is under increasing operational pressure from rising scan volumes, capacity constraints and aging infrastructure," said Kevin Han, Executive Director at Morgan Stanley Expansion Capital. "We believe Subtle Medical's software platform addresses a clear market need by helping providers improve utilization of existing imaging assets, support clinical quality and expand patient access."
The financing is expected to support Subtle Medical's continued product development and commercial expansion across the United States and international markets. Subtle Medical's portfolio includes 11 FDA-cleared software products for MRI, PET and CT workflows, and its technology is deployed on more than 1,300 scanners globally. The Company also continues to develop its AI Imaging Hub, a vendor-neutral platform intended to help providers manage imaging performance across modalities and scanner fleets.
�This is a meaningful moment for Subtle Medical. We have clinical validation, a growing installed base, and a platform architecture that scales across modalities and now the capital and partnership to accelerate that globally," said newly appointed Subtle Medical CEO, Ohad Arazi. "Morgan Stanley Expansion Capital brings a long-term perspective with broad healthcare experience that will be valuable as we expand adoption across modalities and geographies."
Subtle Medical's approach reflects a broader shift toward software-based infrastructure in healthcare, where providers are increasingly seeking tools that can improve productivity, interoperability and access while extending the value of existing capital equipment.
