  "img_finding": "Image findings: ventricular volume measures 67,181 mm³, 123.7% above the reference mean. With a Z-score of 2.94 (99.8th percentile), this represents significant enlargement; hippocampal volume measures 6,613 mm³, 17.6% below the reference mean. With a Z-score of -1.76 (3.9th percentile), this represents moderate atrophy; whole brain volume measures 1,052,490 mm³, 7.2% below the reference mean. With a Z-score of -1.02 (15.3th percentile), this represents mild atrophy; entorhinal cortex volume measures 3,895 mm³, 8.6% below the reference mean. With a Z-score of -0.60 (27.5th percentile), this represents normal volume ; fusiform gyrus volume measures 17,472 mm³, 12.2% below the reference mean. With a Z-score of -1.02 (15.4th percentile), this represents mild atrophy; middle temporal gyrus volume measures 21,101 mm³, 5.8% below the reference mean. With a Z-score of -0.48 (31.5th percentile), this represents normal volume . ",
  "text_data": "Age is 67.4 years. Gender is Male. Education: 15 years. MMSE: 30.0. MoCA: 22.0. Logical Memory: 6.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** The data shows significant ventricular enlargement (Z-score 2.94) and moderate hippocampal atrophy (Z-score -1.76), which are strong indicators of neurodegeneration. The MoCA score of 22 suggests mild cognitive impairment (MCI), while the MMSE of 30 is within normal range, highlighting a discrepancy that may reflect early cognitive decline.  \n\n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **Medium** (due to conflicting MMSE/MoCA scores but strong structural atrophy markers)",
