  "img_finding": "Image findings: ventricular volume measures 14,674 mm³, 60.3% below the reference mean. With a Z-score of -1.63 (5.2th percentile), this represents moderate atrophy; whole brain volume measures 968,368 mm³, 4.3% above the reference mean. With a Z-score of 0.52 (69.8th percentile), this represents normal volume . ",
  "text_data": "Age is 82.2 years. Gender is Female. Education: 16 years. MMSE: 27.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume shows moderate atrophy (Z-score -1.63), but whole brain volume is normal (Z-score 0.52). The MMSE score of 27 is within the normal range, and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild atrophy in ventricular volume but normal cognition and brain volume)",
