The amount of funding invested into the space more than doubled in 2018
Misdiagnosis is a major problem in healthcare: not only are 12 million Americans misdiagnosed each year, nearly a third of these cases result in serious injury, or even death. This is even more serious when it comes to diseases like cancer, where almost half of patients are diagnosed too late thanks to doctors not being able to detect tumors and growths on CT scans and MRIs.
Luckily, technology is coming to the rescue, with companies deploying artificial intelligence, matching learning and deep learning to automatically detect abnormalities that might not be noticeable to the naked eye, enabling patients to start treatment faster.
"Artificial intelligence (AI), including machine learning technologies, has the potential to transform healthcare by deriving new and important insights from the vast amount of data generated during the delivery of health care every day. Radiological applications of AI-based technologies are numerous and expanding. These applications aim to automate and streamline tasks to improve efficiency, accuracy, and consistency," the FDA wrote in an annoucement that it would be holding a public workshop about this very topic later this month.
Of course, venture capitalists are noticing the evolution of the space as well; in 2018, investment in companies developing AI-enabled medical image analysis solutions reached almost $580 million, more than doubling the number from 2017.
They've invested in companies that can analyze radiology images; some that provide teleradiology services, which allow images to be shared with other radiologists in various locations; some that have designed their own medical scanning devices; and some that provide their own radiologists to local groups.

The technology can write in each radiologist’s preferred language, meaning that it automatically generates language that sounds like that person. The radiologist can then review the impression section, and then sign off.

Promaxo is a medical technology company commercializing office-based MRI system and compatible robotic systems. By bringing MRI to office, Promaxo aims to improve access to MRI, a proven technology for diagnosis and treatment planning for several medical conditions, for more patients in an outpatient setting. Additionally, by bringing MRI to outpatient settings, the economic burden on healthcare system reduces dramatically while obviating needs for unnecessary and ineffective screening methods and as many as 50% biopsies. The patients experience high quality of care on a device that is convenient and comfortable while physicians have access to technology at a fraction of the upfront cost and virtually no facility upgrades or maintenance.
Promaxo's technology backed by more than 60 filed and issued patents, is packed into the first single-sided MRI system and MR compatible robot. The system does not require any facility upgrades such as floor reinforcements, shielding, and high electrical power requirements in addition to not requiring hazardous materials like conventional MRIs. The system is small and light enough to be transported to different floor levels in commercial elevators and through the office doors to be easily setup inside an office. The product is currently being evaluated by FDA for 510k clearance.
Promaxo is initially focused on prostate cancer screening, diagnosis and treatment where MRI is considered the best modality for screening, staging and planning. However, its use is limited due to limited access to MRIs for urologists, who typically work in private practices.
The technology is built on the back of more than $8M in grant funding and nearly $7M in dilutive (Seed and Series A) funding. The company is currently closing its $8M bridge to series B at the lower of valuation cap of $32M or 20% discount to Series B and 8% discount rate.
