  "img_finding": "Image findings: ventricular volume measures 17,133 mm³, 23.3% below the reference mean. With a Z-score of -0.58 (28.0th percentile), this represents normal volume ; hippocampal volume measures 8,767 mm³, 14.1% above the reference mean. With a Z-score of 1.58 (94.3th percentile), this represents moderate enlargement; whole brain volume measures 1,113,770 mm³, 8.2% above the reference mean. With a Z-score of 1.02 (84.7th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,437 mm³, 14.0% above the reference mean. With a Z-score of 1.08 (86.1th percentile), this represents mild enlargement; fusiform gyrus volume measures 19,997 mm³, 9.8% above the reference mean. With a Z-score of 1.10 (86.5th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,494 mm³, 5.0% below the reference mean. With a Z-score of -0.44 (32.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume data shows normal or above-average volumes in key regions (hippocampus, whole brain, entorhinal cortex, fusiform gyrus), with no significant atrophy. Cognitive scores (MMSE 29, MoCA 29) are in the normal range, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
