What is “radio imaging” evidence ? The only imaging I saw in the subsequently linked case series was conventional structural MRI … that is to say the imaging cited is evidence of absence (granting other aspects of linked assessment demonstrated a symptom burden which could be attributed to CNS dysfunction). Modern imaging modalities are amazing. Look forward to having the radio imaging finding highlighted.
