  "img_finding": "Image findings: ventricular volume measures 52,582 mm³, 87.3% above the reference mean. With a Z-score of 2.00 (97.7th percentile), this represents moderate enlargement; hippocampal volume measures 6,712 mm³, 5.7% below the reference mean. With a Z-score of -0.52 (30.2th percentile), this represents normal volume ; whole brain volume measures 993,040 mm³, 1.9% above the reference mean. With a Z-score of 0.24 (59.4th percentile), this represents normal volume . ",
  "text_data": "Age is 76.8 years. Gender is Female. Education: 12 years. Handedness: Right. Race: White.

  "gpt_diagnosis": "Reasoning: The data shows moderate ventricular enlargement (87.3% above reference mean) but normal hippocampal and whole brain volumes. The MMSE score of 25 is borderline, while the MoCA score of 19 suggests mild cognitive impairment. Biomarkers (T-tau, P-tau) are normal, and AV45 indicates mild amyloid reduction.  \nDiagnosis: MCI  \nConfidence: Medium",
