PERIMETER MEDICAL IMAGING AI REPORTS ITS PROPRIETARY ARTIFICIAL INTELLIGENCE ALGORITHM + OCT IDENTIFIED 96.8% OF POSITIVE BREAST CANCER MARGINS IN NEWLY PUBLISHED PEER REVIEWED STUDY

Perimetre Medical Imaging AI Inc. has released results from a peer-reviewed retrospective study examining the integration of wide field optical coherence tomography (WF-OCT) with Perimetre'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 per cent of pathology-positive margins. These results highlight the clinical viability of AI-enhanced (artificial intelligence) margin visualization using WF-OCT in breast cancer surgery and its potential to decrease reoperation rates due to residual tumours.

Adrian Mendes, Perimetre'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 health care settings and used our vast image library to train these models to achieve an industry-leading result. Perimetre'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."

A continuing, multicentre, randomized, two-arm, pivotal clinical trial -- led by principal investigator Dr. Alastair Thompson at Baylor College of Medicine -- is evaluating the use of Perimetre B-Series OCT combined with its proprietary ImgAssist AI software during breast conservation surgery. Perimetre intends to conduct a planned interim analysis in the second quarter of 2024, with study completion anticipated by the end of 2024.
