  "img_finding": "Image findings: ventricular volume measures 18,202 mm³, 18.5% below the reference mean. With a Z-score of -0.46 (32.2th percentile), this represents normal volume ; whole brain volume measures 896,497 mm³, 12.9% below the reference mean. With a Z-score of -1.60 (5.4th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 68.5 years. Gender is Female. Education: 16 years. MMSE: 26.0. MoCA: 25.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows moderate whole brain atrophy (Z-score -1.60, 5.4th percentile) but normal ventricular volume. Cognitive scores (MMSE 26, MoCA 25) are borderline but still within normal limits for age. No APOE4 risk allele is present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline cognitive scores despite structural atrophy)",
