GREY MATTERS APPOINTS RADIOLOGIST DR. JAYSON A. LORD, MD AS MEDICAL DIRECTOR OF ITS FIRST DEDICATED PET NEUROIMAGING CLINIC IN THE U.S.

Grey Matters Health Inc. has appointed radiologist Dr. Jayson A. Lord, MD, as the medical director of its flagship NovaScan Neuroimaging Clinics location opening in September, 2026, in Davie, Fla.

"We are very pleased to have Dr. Lord, who is a board-certified, veteran radiologist practicing in Florida, join the NovaScan Neuroimaging team", said Christopher J. Moreau, chief executive officer of Grey Matters Health. "Dr. Lord will provide the medical oversight for all clinical operations and is responsible for ensuring that all our patients receive the highest quality of positron emission tomography (PET) diagnostic brain imaging services."

"I am very excited about the significance of NovaScan Neuroimaging being the first in the U.S. to introduce the CareMiBrain system to the market with its seated scan design," said Dr. Lord. "On an immediate basis, we will be working to provide patients with shorter wait times for brain dedicated PET scans along with a greatly enhanced and optimized patient experience overall. In the bigger picture, our work will contribute to advancing the science of brain PET scan imaging for many neuro-degenerative diseases, with the ultimate goal of deepening our understanding of these conditions, improving the development of new treatments, and, in some cases, helping to find cures."

About Dr. Jayson A. Lord

Dr. Lord is a board-certified diagnostic radiologist with over 25 years of experience. He earned his undergraduate degree from the University of Florida and his medical degree from the University of South Florida Morsani College of Medicine in 1995, where he also completed his residency. He is board certified by the American Board of Radiology and the National Board of Medical Examiners. He is licensed to practice radiology in 12 U.S. states including Florida and has been an owner and partner in several private radiology practices since graduation.

U.S. flagship -- NovaScan Neuroimaging Clinics

The inaugural NovaScan Neuroimaging Clinics location is at the HCA Florida University Medical Office Building in Davie, located on the campus of the HCA Florida University Hospital, and will be the first of its kind in the United States to provide brain dedicated PET scans to aid in the detection of Alzheimer's Disease (AD) and other forms of neurodegenerative diseases including frontotemporal dementia, Parkinson's and Lewy Body Dementia, and will be additionally used for other select neuro-oncology applications.

Brain PET scans for beta-amyloid plaque detection (associated with advancing AD) are covered by Medicare, Medicaid and private insurance for those 65-plus, with patients being referred to NovaScan Neuroimaging Clinics by neurologists, geriatricians and primary care physicians. The clinic will feature the U.S. Food and Drug Administration-cleared CareMiBrain system, a ground-breaking, new seated diagnostic brain PET scanner, that does not need an integrated computed Tomography (CT) component to produce high-quality images, resulting in 25-per-cent less radiation exposure for patients.

The CareMiBrain PET brain scanning system

There are two recently U.S. FDA approved monoclonal antibody treatments for AD, which are also covered by Medicare, Medicaid and private insurance, designed to slow the progression of the disease -- Leqembi (Eisai and Biogen) and Kisunla (Eli Lilly) -- and both require a positive beta-amyloid brain scan (or spinal tap) in order for patients to be authorized to receive them. These drugs can dissolve amyloid plaque build-up in the brain and slow the progression of a patient's cognitive decline and have helped create a billion-dollar market opportunity for the brain specific PET scan and AD treatment space.

The United States' current supply of PET scanners -- the majority being a PET/CT hybrid technology -- is vastly insufficient to serve the massive new market emerging for AD diagnostics and treatment. The majority of PET/CT scanners, 45 per cent of which are located in hospitals, are primarily prioritized as cancer diagnostic and theranostic tools, and for cardiac imaging, which can make it challenging to schedule brain-specific scans on a timely basis.

The Grey Matters Health business plan is to open a national chain of its NovaScan Neuroimaging Clinics throughout the U.S.

The company also announces a grant of 885,000 restricted share units pursuant to its RSU plan to certain executives, employees and directors, of the company. Each RSU entitles the recipient to receive one common share of the company or a cash payment equal to the equivalent of one common share of the company on vesting. The RSUs vest on the date of grant.
