  "img_finding": "Image findings: ventricular volume measures 20,951 mm³, 12.5% above the reference mean. With a Z-score of 0.36 (64.0th percentile), this represents normal volume ; hippocampal volume measures 7,254 mm³, 7.1% below the reference mean. With a Z-score of -0.99 (16.2th percentile), this represents normal volume ; whole brain volume measures 1,045,900 mm³, 0.5% above the reference mean. With a Z-score of 0.06 (52.5th percentile), this represents normal volume ; entorhinal cortex volume measures 5,311 mm³, 43.7% above the reference mean. With a Z-score of 3.42 (100.0th percentile), this represents profound enlargement; fusiform gyrus volume measures 20,953 mm³, 13.7% above the reference mean. With a Z-score of 1.24 (89.3th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,524 mm³, 4.9% below the reference mean. With a Z-score of -0.41 (34.3th percentile), this represents normal volume . ",
  "text_data": "Age is 58.9 years. Gender is Female. Education: 16 years. MMSE: 30.0. MoCA: 29.0. Logical Memory: 17.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The brain volume data shows normal ventricular, hippocampal, whole brain, and middle temporal gyrus volumes, with mild enlargement in the fusiform gyrus and profound enlargement in the entorhinal cortex. Cognitive scores (MMSE 30, MoCA 29) are intact, and there is no APOE4 risk allele.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (entorhinal cortex enlargement is atypical but not clearly pathological given intact cognition and other normal volumes)",
