  "img_finding": "Image findings: ventricular volume measures 47,645 mm³, 69.7% above the reference mean. With a Z-score of 1.60 (94.5th percentile), this represents moderate enlargement; hippocampal volume measures 4,731 mm³, 33.5% below the reference mean. With a Z-score of -3.07 (0.1th percentile), this represents profound atrophy; whole brain volume measures 987,126 mm³, 1.3% above the reference mean. With a Z-score of 0.16 (56.4th percentile), this represents normal volume . ",
  "text_data": "Age is 74.6 years. Gender is Female. Education: 20 years. MMSE: 25.0. MoCA: 22.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The data shows profound hippocampal atrophy (Z-score -3.07) and moderate ventricular enlargement, both indicative of neurodegeneration, while whole brain volume remains normal. The cognitive scores (MMSE 25, MoCA 22) are borderline but not severely impaired, suggesting early cognitive decline.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium (cognitive scores are borderline, but hippocampal atrophy strongly suggests progression toward dementia)",
