  "img_finding": "Image findings: ventricular volume measures 58,186 mm³, 93.8% above the reference mean. With a Z-score of 2.23 (98.7th percentile), this represents significant enlargement; hippocampal volume measures 4,359 mm³, 45.7% below the reference mean. With a Z-score of -4.57 (0.0th percentile), this represents profound atrophy; whole brain volume measures 1,032,650 mm³, 9.0% below the reference mean. With a Z-score of -1.27 (10.2th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound hippocampal atrophy (Z-score -4.57) and significant ventricular enlargement (Z-score 2.23), which are strong indicators of neurodegeneration. Despite a normal MMSE score, the MoCA score of 22 suggests mild cognitive impairment, and the absence of APOE4 does not rule out Alzheimer's pathology given the structural changes.  \nDiagnosis: MCI  \nConfidence: Medium",
