  "img_finding": "Image findings: ventricular volume measures 38,032 mm³, 1.3% below the reference mean. With a Z-score of -0.03 (48.8th percentile), this represents normal volume ; hippocampal volume measures 7,847 mm³, 3.8% above the reference mean. With a Z-score of 0.37 (64.5th percentile), this represents normal volume ; whole brain volume measures 1,058,490 mm³, 1.9% below the reference mean. With a Z-score of -0.25 (40.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, hippocampal, and whole brain) are within normal ranges, and biomarkers (T-tau, P-tau, AV45) do not strongly indicate Alzheimer's pathology. However, the MoCA score of 23 suggests mild cognitive impairment, while the MMSE of 30 is normal, creating some discrepancy.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (due to conflicting cognitive scores but normal biomarkers and brain volumes)",
