Advancements in Imaging for Endometriosis and Rheumatoid Arthritis

Overview of 99 mTc-Maraciclatide

In our ongoing series “From Lab to Clinic,” we have explored the development of 99 mTc-maraciclatide, an imaging molecule currently being researched for its application in diagnosing endometriosis. Recently, this growing blood vessel labeling agent has also emerged as a significant marker for rheumatoid arthritis.

Presentation at MICCAI 2024

This month, experts from King’s College London showcased their latest findings at the 2024 Medical Image Computing and Computer Assisted Intervention Society (MICCAI) meeting held in Morocco. The research team, led by Professors Andrew Reader and Gary Cook from the School of Biomedical Engineering and Imaging Sciences at King’s College London (KCL), presented compelling data indicating that 99 mTc-maraciclatide distinctly accumulates around arthritic joints, effectively pinpointing inflammation.

Implications for Rheumatoid Arthritis Imaging

A notable highlight from the presentation was by Robert Cobb, who revealed that the team had leveraged 99 mTc-maraciclatide imaging to create an innovative training method for automated radiology software. This pioneering approach utilized generative AI image recognition technology to differentiate between various levels of inflammation signals and the background noise in images.

The AI model was trained to identify inflammation in knuckle joints while distinguishing it from the less defined outlines of the rest of the hand. To facilitate this, the researchers provided the AI program with 8,000 images generated by the SPEC/CT system, which were meticulously labeled by radiologists to indicate the location and intensity of each signal. By exposing the model to diverse hand shapes and varying inflammation levels, it learned to discern genuine inflammatory signals from background artifacts.

The outcome of this research has enabled the AI program to categorize images into groups based on inflammation severity, including high, low, and baseline levels observed in non-arthritic hands, commonly referred to as “normal.”
