  "img_finding": "Image findings: ventricular volume measures 123,835 mm³, 163.4% above the reference mean. With a Z-score of 4.75 (100.0th percentile), this represents profound enlargement; whole brain volume measures 898,063 mm³, 12.7% below the reference mean. With a Z-score of -1.67 (4.8th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement (Z-score 4.75) and moderate whole brain atrophy (Z-score -1.67), which are strong indicators of neurodegeneration. Despite the high MMSE score (28/30), the structural changes are concerning for early cognitive decline, especially given the presence of one APOE4 allele.  \nDiagnosis: MCI  \nConfidence: Medium (due to the discrepancy between imaging findings and preserved MMSE score)",
