  "img_finding": "Image findings: ventricular volume measures 18,913 mm³, 15.3% below the reference mean. With a Z-score of -0.38 (35.1th percentile), this represents normal volume ; hippocampal volume measures 8,232 mm³, 7.1% above the reference mean. With a Z-score of 0.80 (78.8th percentile), this represents normal volume ; whole brain volume measures 1,172,730 mm³, 14.0% above the reference mean. With a Z-score of 1.74 (95.9th percentile), this represents moderate enlargement; entorhinal cortex volume measures 4,413 mm³, 13.4% above the reference mean. With a Z-score of 1.04 (85.0th percentile), this represents mild enlargement; fusiform gyrus volume measures 23,449 mm³, 28.8% above the reference mean. With a Z-score of 3.24 (99.9th percentile), this represents profound enlargement; middle temporal gyrus volume measures 22,717 mm³, 10.7% above the reference mean. With a Z-score of 0.95 (82.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume data shows normal to enlarged volumes in key regions (hippocampus, entorhinal cortex, fusiform gyrus), with no atrophy. Cognitive scores are strong (MMSE 30, MoCA 25), and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
