  "img_finding": "Image findings: ventricular volume measures 31,812 mm³, 17.4% below the reference mean. With a Z-score of -0.42 (33.8th percentile), this represents normal volume ; whole brain volume measures 990,398 mm³, 8.2% below the reference mean. With a Z-score of -1.07 (14.2th percentile), this represents mild atrophy. ",
  "text_data": "Age is 77.3 years. Gender is Male. Education: 18 years. Handedness: Right. Race: White. Medical history: Psychiatric; Gastrointestinal; Renal-Genitourinary; Major Surgical Procedures. MMSE: 29.0. Logical Memory: 16.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The ventricular volume is within normal limits, but there is mild whole brain atrophy (14.2th percentile). However, cognitive function appears intact (MMSE 29/30), and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (mild atrophy could be age-related, but no cognitive impairment is present)",
