  "img_finding": "Image findings: ventricular volume measures 86,151 mm³, 123.7% above the reference mean. With a Z-score of 2.96 (99.8th percentile), this represents significant enlargement; whole brain volume measures 969,673 mm³, 10.2% below the reference mean. With a Z-score of -1.32 (9.3th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (123.7% above mean, Z-score 2.96) and mild whole brain atrophy (10.2% below mean, Z-score -1.32), which are consistent with neurodegenerative changes. The MMSE score of 25 is borderline, but combined with structural changes and APOE4 positivity, this suggests cognitive impairment.  \nDiagnosis: MCI  \nConfidence: Medium",
