  "img_finding": "Image findings: ventricular volume measures 37,400 mm³, 1.2% above the reference mean. With a Z-score of 0.03 (51.3th percentile), this represents normal volume ; whole brain volume measures 812,486 mm³, 12.5% below the reference mean. With a Z-score of -1.50 (6.7th percentile), this represents mild atrophy. ",
  "text_data": "Age is 84.4 years. Gender is Female. Education: 16 years. MMSE: 24.0. Laboratory findings: Serum Glucose: 141.00 (profound elevated). APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.50, 6.7th percentile) with preserved ventricular volume, which is concerning but not definitive for dementia. The MMSE score of 24 is borderline (mild cognitive impairment range for this age), and the presence of one APOE4 allele increases Alzheimer's risk.  \n\nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (Brain atrophy and MMSE suggest cognitive decline, but not severe enough for dementia diagnosis without further functional assessment.)",
