  "img_finding": "Image findings: ventricular volume measures 44,596 mm³, 5.1% below the reference mean. With a Z-score of -0.15 (44.1th percentile), this represents normal volume ; hippocampal volume measures 6,462 mm³, 7.3% below the reference mean. With a Z-score of -0.63 (26.5th percentile), this represents normal volume ; whole brain volume measures 1,021,920 mm³, 0.7% below the reference mean. With a Z-score of -0.09 (46.3th percentile), this represents normal volume ; entorhinal cortex volume measures 5,160 mm³, 30.0% above the reference mean. With a Z-score of 1.96 (97.5th percentile), this represents moderate enlargement; fusiform gyrus volume measures 16,606 mm³, 8.1% below the reference mean. With a Z-score of -0.70 (24.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,070 mm³, 0.5% below the reference mean. With a Z-score of -0.05 (48.2th percentile), this represents normal volume . ",
  "text_data": "Age is 83.4 years. Gender is Male. Education: 20 years. MMSE: 29.0. MoCA: 25.0. Logical Memory: 12.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The brain volume measurements are largely within normal ranges, with only the entorhinal cortex showing moderate enlargement (Z-score 1.96, 97.5th percentile). Cognitive scores (MMSE 29, MoCA 25) are borderline for MCI but still within normal limits for age. No APOE4 risk allele is present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MoCA score but otherwise normal findings)",
