  "img_finding": "Image findings: ventricular volume measures 55,263 mm³, 43.5% above the reference mean. With a Z-score of 1.04 (85.1th percentile), this represents mild enlargement; hippocampal volume measures 7,011 mm³, 7.3% below the reference mean. With a Z-score of -0.71 (24.0th percentile), this represents normal volume ; whole brain volume measures 1,106,670 mm³, 2.5% above the reference mean. With a Z-score of 0.33 (62.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,859 mm³, 18.5% above the reference mean. With a Z-score of 1.25 (89.5th percentile), this represents mild enlargement; fusiform gyrus volume measures 15,690 mm³, 16.7% below the reference mean. With a Z-score of -1.42 (7.7th percentile), this represents mild atrophy; middle temporal gyrus volume measures 21,834 mm³, 2.3% above the reference mean. With a Z-score of 0.21 (58.3th percentile), this represents normal volume . ",
  "text_data": "Age is 73.6 years. Gender is Male. Education: 18 years. MMSE: 30.0. Logical Memory: 16.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The patient shows mild ventricular enlargement and mild fusiform gyrus atrophy, but hippocampal volume is normal, and MMSE is intact (30/30). No APOE4 risk alleles are present. These findings are not strongly indicative of neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild structural changes despite normal cognition)",
