GE HealthCare
The 130-year medical-technology lineage is no longer selling scanners alone. Its bet is that imaging hardware, diagnostic drugs, cloud software and AI can work as one connected care system - without asking clinicians to become IT departments.
Braid Health
Braid Health is a San Francisco health-tech company building an FDA-cleared, AI-powered diagnostic collaboration platform for medical imaging. Founded in 2018 by Apple and Twitter alumni Kevin Quennesson and Alessandro Sabatelli, Braid pairs AI imaging copilots with board-certified radiologists to deliver faster, lower-cost reads of MRI, CT, ultrasound and X-ray studies. It serves urgent care networks, health systems and retail clinics, and in 2026 launched a direct-to-patient second-opinion service that offers expert radiologist re-reads for $199.
Vista AI
Vista AI (formerly HeartVista) builds AI software that automates MRI exams so any technologist can capture consistent, high-quality scans without a specialist on site. Spun out of Stanford's Magnetic Resonance Systems Research Lab in 2012, its FDA-cleared cardiac MRI product turns a manual, expert-dependent procedure into a largely automated one, and the company is expanding into brain, prostate and spine imaging. Backed by Khosla Ventures and a roster of major U.S. health systems, Vista AI positions automation as a fix for the gap between soaring MRI demand and a shortage of skilled technologists.
Alara Imaging
Alara Imaging is a San Francisco healthcare technology company building a private compute platform for radiology. Its flagship product, the Alara Medical Imaging Gateway, is edge-orchestration software that sits inside a hospital and moves imaging data securely and bidirectionally between facilities and the cloud. Founded out of UCSF research, Alara serves as a CMS measure steward, giving health systems a HITRUST-certified, HIPAA- and SOC 2-compliant way to calculate and report new radiology quality measures - including a CMS-endorsed measure to standardize CT radiation doses and reduce avoidable cancer risk.
PaxeraHealth
PaxeraHealth is a Boston-area medical imaging company that builds AI-driven enterprise imaging software - PACS, vendor-neutral archives, image sharing, and a no-code platform that lets hospitals author their own imaging algorithms. Founded in 2009 by Dr. Mohamed Shoura, the company has installed thousands of PACS systems across 50+ countries and counts the American College of Radiology and AdventHealth among its clients.
Eden
Eden is a Latin American health-tech company building the leading cloud PACS/RIS platform for radiology - storage, viewing, AI-assisted reading, and digital delivery of medical imaging used by hospitals and clinics across 17 countries. Founded by Julián Ríos Cantú, who first became known as the teenager behind the EVA breast-cancer-detecting bra, Eden processes millions of medical images a day and has raised roughly $44M total, including a $10M round led by Sierra Ventures and a Series A in October 2025.
Prenuvo
Prenuvo runs a chain of clinics built around a 60-minute whole-body MRI designed to spot cancer, aneurysms and hundreds of other conditions before symptoms show up. Founded by Andrew Lacy and radiologist Raj Attariwala, the company is trying to drag American healthcare from reactive to preventive, one scan at a time.
Rad AI
Rad AI builds generative-AI software that drafts the most tedious parts of a radiology report - the impressions, the follow-ups, the boilerplate - so radiologists can spend more time on the images and less on the keyboard. Founded in 2018 by a radiologist (Jeff Chang) and a serial founder (Doktor Gurson), the company now works with roughly nine of the ten largest radiology groups in the U.S. and touches close to half of the country's medical imaging.
RapidAI
RapidAI builds FDA-cleared clinical AI software that reads CT, CTA, CT perfusion and MRI scans to flag stroke, aneurysms and pulmonary embolisms in minutes - giving hospital teams a faster path to treatment. The platform began life as the Stanford spin-out iSchemaView and now runs in more than 2,000 hospitals across 100+ countries.
Sirona Medical
Sirona Medical is a San Francisco cloud-native radiology software company building Unify, a single platform that fuses PACS, viewer, worklist, reporting and AI into one browser-based workflow for radiologists.
Subtle Medical
Subtle Medical is a Stanford-born AI company that makes regular MRI and PET scanners faster and sharper through deep learning denoising and image enhancement software. Its FDA-cleared, vendor-neutral products - including SubtlePET, SubtleMR/SubtleHD, SubtleSYNTH and AiMIFY - help radiology departments shorten scan times, reduce contrast dose, and increase patient throughput without buying new hardware.
VELMENI
VELMENI is a Sunnyvale-based dental AI platform that uses computer vision and deep learning to analyze 2D and 3D dental radiographs in real time. Its FDA-cleared flagship product, VELMENI for DENTISTS, is the first dental AI approved to detect pathologies in panoramic X-rays — catching caries, bone loss, and other findings that experienced clinicians miss roughly one-third of the time. Beyond diagnostics, the platform automates insurance claims, enables voice-assisted periodontal charting, interprets CBCT scans, and delivers VR-based patient education, all from a single integrated workflow. Founded in 2020 by CEO Mini Suri and Chief Dental Officer Dr. Arvin Oberai, the company has been beta-tested by over 1,300 dentists across 500+ practices in 50+ countries.
