  "img_finding": "Image findings: ventricular volume measures 48,159 mm³, 71.6% above the reference mean. With a Z-score of 1.64 (94.9th percentile), this represents moderate enlargement; whole brain volume measures 979,162 mm³, 0.5% above the reference mean. With a Z-score of 0.06 (52.3th percentile), this represents normal volume . ",
  "text_data": "Age is 76.9 years. Gender is Female. Education: 16 years. Handedness: Right. Race: White. Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat; Musculoskeletal; Gastrointestinal; Major Surgical Procedures. MMSE: 28.0. MoCA: 22.0. Logical Memory: 9.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume is moderately enlarged (71.6% above reference mean, Z-score 1.64), suggesting possible atrophy, while whole brain volume is normal. The MMSE (28/30) is normal, but the MoCA (22/30) indicates mild cognitive impairment, which, combined with ventricular enlargement, suggests early neurodegeneration.  \n\n**Diagnosis:** **MCI** (Mild Cognitive Impairment)  \n**Confidence:** **Medium** (due to conflicting MMSE/MoCA scores but structural changes supporting MCI)",
