  "img_finding": "Image findings: ventricular volume measures 53,467 mm³, 90.5% above the reference mean. With a Z-score of 2.07 (98.1th percentile), this represents significant enlargement; whole brain volume measures 868,451 mm³, 10.9% below the reference mean. With a Z-score of -1.37 (8.5th percentile), this represents mild atrophy. ",
  "text_data": "Age is 79.1 years. Gender is Female. Education: 18 years. MMSE: 30.0. Logical Memory: 11.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (90.5% above reference mean) and mild whole brain atrophy (10.9% below reference mean), which are structural changes often associated with neurodegenerative processes. However, the MMSE score of 30.0 (perfect) and absence of APOE4 suggest no current cognitive impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (structural changes are concerning, but cognitive performance is intact)",
