  "img_finding": "Image findings: ventricular volume measures 53,980 mm³, 46.0% above the reference mean. With a Z-score of 1.24 (89.3th percentile), this represents mild enlargement; whole brain volume measures 946,436 mm³, 2.0% above the reference mean. With a Z-score of 0.24 (59.3th percentile), this represents normal volume . ",
  "text_data": "Age is 85.4 years. Gender is Female. Education: 16 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Dermatologic-Connective Tissue; Musculoskeletal; Gastrointestinal; Renal-Genitourinary; Smoking; Major Surgical Procedures. MMSE: 27.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The ventricular volume is mildly enlarged (46% above reference mean), which can be associated with atrophy, but whole brain volume is normal. The MMSE score of 27 is within the normal range (≥26), and the absence of APOE4 reduces genetic risk.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (mild ventricular enlargement could suggest early changes, but cognitive performance is intact)",
