  "img_finding": "Image findings: ventricular volume measures 38,572 mm³, 18.0% below the reference mean. With a Z-score of -0.52 (30.1th percentile), this represents normal volume ; whole brain volume measures 958,143 mm³, 6.9% below the reference mean. With a Z-score of -0.90 (18.3th percentile), this represents normal volume . ",
  "text_data": "Age is 80.9 years. Gender is Male. Education: 13 years. MMSE: 27.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The ventricular and whole brain volumes are within normal ranges (Z-scores -0.52 and -0.90, respectively), and the MMSE score of 27 is within the normal range for cognitive function. There is no significant atrophy or cognitive impairment indicated.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (While the data suggests normal cognition, clinical correlation and longitudinal follow-up would increase confidence.)",
