  "img_finding": "Image findings: hippocampal volume measures 6,981 mm³, 7.6% below the reference mean. With a Z-score of -0.75 (22.8th percentile), this represents normal volume ; whole brain volume measures 1,216,680 mm³, 12.7% above the reference mean. With a Z-score of 1.65 (95.1th percentile), this represents moderate enlargement; entorhinal cortex volume measures 3,705 mm³, 9.6% below the reference mean. With a Z-score of -0.65 (25.6th percentile), this represents normal volume ; fusiform gyrus volume measures 21,807 mm³, 15.8% above the reference mean. With a Z-score of 1.34 (91.0th percentile), this represents mild enlargement; middle temporal gyrus volume measures 24,306 mm³, 13.9% above the reference mean. With a Z-score of 1.25 (89.4th percentile), this represents mild enlargement. ",
  "text_data": "Age is 76.4 years. Gender is Male. Education: 18 years. MMSE: 29.0. MoCA: 24.0. Logical Memory: 9.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The hippocampal and entorhinal cortex volumes are within normal ranges (Z-scores > -1.0), while other regions show mild to moderate enlargement. The MMSE score is normal (29/30), but the MoCA score (24/30) suggests mild cognitive impairment. No APOE4 risk allele is present.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (due to normal hippocampal volume but borderline MoCA score)",
