T1w/T2w Ratio Analysis in Anti-NMDAR Encephalitis Patients

Jinyu Tao published a dataset on figshare in April 2026. It contains T1-weighted/T2-weighted ratio measurements from MRI scans of 59 patients with anti-NMDAR encephalitis and 34 healthy controls. The data includes longitudinal follow-up for 18 patients over 12 months.

Use Cases

• Correlating MRI-derived T1w/T2w ratios with cognitive test scores based on the Montreal Cognitive Assessment (MoCA).
• Analyzing longitudinal changes in white matter microstructure over a 12-month follow-up period.
• Comparing microstructural alterations in specific white matter tracts like the corpus callosum and fornix between patient subgroups.
• Investigating the relationship between T1w/T2w ratios and domain-specific cognitive functions like memory and visuospatial reasoning.

Strengths

• Includes longitudinal data from 18 patients over 12 months.
• Compares three distinct cohorts: 59 patients (31 with MCI, 28 without) and 34 healthy controls.
• Links imaging metrics to results from comprehensive neuropsychological assessments like MoCA and MMSE.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is 26.9 KB, indicating a very limited scope.
