  "img_finding": "Image findings: ventricular volume measures 15,249 mm³, 58.7% below the reference mean. With a Z-score of -1.59 (5.6th percentile), this represents moderate atrophy; whole brain volume measures 962,993 mm³, 3.8% above the reference mean. With a Z-score of 0.45 (67.4th percentile), this represents normal volume . ",
  "text_data": "Age is 83.7 years. Gender is Female. Education: 16 years. MMSE: 28.0. Logical Memory: 6.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The ventricular volume shows moderate atrophy (Z-score -1.59), but whole brain volume is normal (Z-score 0.45). The MMSE score of 28 is within the normal range, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to mild atrophy but strong cognitive performance and no genetic risk)",
