In an X post announcing the diagnosis, Bryan Johnson said his partner Kate was officially diagnosed with endometriosis without surgery after 42 days of testing across “imaging, blood, and AI.” He also said the process surfaced two other diagnoses at the same time, and later pointed readers to a Matricis AI clinical trial post on X, where he claimed radiologists can miss lesions in up to 60% of cases. So far, the public account comes from Johnson’s own posts on X.
