PET scan is a highly sensitive biomarker for autoimmune encephalitis, new data suggest

A PET scan may be an early and highly sensitive biomarker of autoimmune encephalitis, according to new data presented at AOCN-IANCON 2022.

The diagnostic sensitivity of MRI for autoimmune encephalitis is poor, according to researchers at the King Edward Memorial Hospital in Mumbai, India. In a previous study, only 53% of patients with autoimmune encephalitis had abnormal MRI findings.
