  "img_finding": "Image findings: ventricular volume measures 26,124 mm³, 32.2% below the reference mean. With a Z-score of -0.77 (22.0th percentile), this represents normal volume ; whole brain volume measures 971,350 mm³, 10.0% below the reference mean. With a Z-score of -1.30 (9.7th percentile), this represents mild atrophy. ",
  "text_data": "Age is 73.5 years. Gender is Male. Education: 12 years. Handedness: Right. Race: White. Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat; Dermatologic-Connective Tissue; Smoking. MMSE: 27.0. Logical Memory: 4.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.30, 9.7th percentile) but normal ventricular volume. The MMSE score of 27 is within the normal range (≥26), and the absence of APOE4 reduces genetic risk. No significant cognitive impairment is indicated clinically.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy is present but not accompanied by cognitive deficits)",
