  "img_finding": "Image findings: ventricular volume measures 70,078 mm³, 49.0% above the reference mean. With a Z-score of 1.42 (92.3th percentile), this represents mild enlargement; hippocampal volume measures 6,057 mm³, 13.1% below the reference mean. With a Z-score of -1.13 (12.9th percentile), this represents mild atrophy; whole brain volume measures 1,067,040 mm³, 3.7% above the reference mean. With a Z-score of 0.48 (68.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,192 mm³, 19.6% below the reference mean. With a Z-score of -1.28 (10.0th percentile), this represents mild atrophy; fusiform gyrus volume measures 21,470 mm³, 18.8% above the reference mean. With a Z-score of 1.63 (94.9th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 21,708 mm³, 7.6% above the reference mean. With a Z-score of 0.68 (75.3th percentile), this represents normal volume . ",
  "text_data": "Age is 80.1 years. Gender is Male. Education: 19 years. MMSE: 30.0. MoCA: 24.0. Logical Memory: 13.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The data shows mild hippocampal and entorhinal cortex atrophy, which are early markers of Alzheimer's pathology, alongside ventricular enlargement (a nonspecific marker of brain atrophy). The MMSE is normal, but the MoCA score of 24 suggests mild cognitive impairment. The presence of one APOE4 allele increases Alzheimer's risk.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (Cognitive scores and imaging suggest MCI, but clinical correlation is needed to rule out other causes.)",
