  "img_finding": "Image findings: ventricular volume measures 31,875 mm³, 17.2% below the reference mean. With a Z-score of -0.41 (34.0th percentile), this represents normal volume ; hippocampal volume measures 8,217 mm³, 8.7% above the reference mean. With a Z-score of 0.85 (80.2th percentile), this represents normal volume ; whole brain volume measures 1,207,860 mm³, 11.9% above the reference mean. With a Z-score of 1.54 (93.9th percentile), this represents moderate enlargement; entorhinal cortex volume measures 4,848 mm³, 18.2% above the reference mean. With a Z-score of 1.24 (89.2th percentile), this represents mild enlargement; fusiform gyrus volume measures 23,488 mm³, 24.7% above the reference mean. With a Z-score of 2.10 (98.2th percentile), this represents significant enlargement; middle temporal gyrus volume measures 27,479 mm³, 28.8% above the reference mean. With a Z-score of 2.59 (99.5th percentile), this represents significant enlargement. ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements show normal to enlarged volumes across all regions, with no atrophy typically seen in Alzheimer's disease. The MMSE score of 30 is perfect, and the MoCA score of 26 is within the normal range (≥26). The absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
