  "img_finding": "Image findings: ventricular volume measures 56,248 mm³, 19.6% above the reference mean. With a Z-score of 0.57 (71.6th percentile), this represents normal volume ; whole brain volume measures 851,239 mm³, 17.3% below the reference mean. With a Z-score of -2.27 (1.2th percentile), this represents significant atrophy. ",
  "text_data": "Age is 81.8 years. Gender is Male. Education: 16 years. Handedness: Right. Race: Black or African American. Medical history: Cardiovascular; Musculoskeletal; Endocrine-Metabolic; Renal-Genitourinary; Malignancy. MMSE: 27.0. Logical Memory: 8.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The patient shows significant whole brain atrophy (Z-score -2.27, 1.2th percentile) but normal ventricular volume. The MMSE score of 27 is within the normal range, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: Mild Cognitive Impairment (MCI)  \nConfidence: Medium  \n\n(Reasoning: While the brain atrophy is severe, the preserved MMSE suggests no major functional decline yet. The absence of APOE4 and normal ventricular volume temper the likelihood of rapid progression, but the atrophy still indicates MCI rather than normal aging.)",
