DALLAS and TORONTO, Feb. 29, 2024 /PRNewswire/ - Perimeter Medical Imaging AI, Inc. (TSXV: PINK) (OTC: PYNKF) (FSE: 4PC) ("Perimeter" or the "Company") – a commercial-stage medical technology company – announced results from a peer-reviewed retrospective study¹ examining the integration of Wide Field Optical Coherence Tomography (WF-OCT) with Perimeter's proprietary and investigational "ImgAssist" artificial intelligence technology, an AI-driven clinical decision support system created to enhance productivity and decision making in breast cancer surgery margin assessment.

From a clinical perspective, the deep learning model showed high levels of sensitivity and specificity, accurately identifying 96.8% of pathology-positive margins. These results highlight the clinical viability of AI-enhanced margin visualization using WF-OCT in breast cancer surgery and its potential to decrease reoperation rates due to residual tumors.

Adrian Mendes, Perimeter's Chief Executive Officer, stated, "We have a training dataset of several million proprietary images of both cancerous and healthy tissue captured with our OCT imaging technology. Our world-class AI team has developed models tailored for real-time applications in healthcare settings and used our vast image library to train these models to achieve an industry-leading result. Perimeter's AI leadership represents a key value driver as we build a product pipeline that aims to improve surgical outcomes and broaden our addressable market through a variety of tissue types beyond breast."

An ongoing, multi-center, randomized, two-arm, pivotal clinical trial – led by Principal Investigator, Dr. Alastair Thompson at Baylor College of Medicine – is evaluating the use of Perimeter B-Series OCT combined with its proprietary ImgAssist AI software during breast conservation surgery. Perimeter intends to conduct a planned interim analysis in the second quarter of 2024, with study completion anticipated by the end of 2024.
