  "img_finding": "Image findings: ventricular volume measures 39,431 mm³, 40.5% above the reference mean. With a Z-score of 0.93 (82.3th percentile), this represents normal volume ; whole brain volume measures 918,861 mm³, 5.7% below the reference mean. With a Z-score of -0.72 (23.6th percentile), this represents normal volume . ",
  "text_data": "Age is 73.5 years. Gender is Female. Education: 16 years. MMSE: 29.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is slightly above the reference mean but still within normal range (Z-score 0.93), and whole brain volume is slightly below the reference mean but also within normal range (Z-score -0.72). The MMSE score of 29 is within the normal range, and there are no significant cognitive complaints reported.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (while imaging and MMSE are normal, the presence of one APOE4 allele slightly increases future risk but does not indicate current impairment)",
