  "img_finding": "Image findings: ventricular volume measures 12,348 mm³, 33.7% below the reference mean. With a Z-score of -0.96 (16.7th percentile), this represents normal volume ; hippocampal volume measures 8,798 mm³, 12.7% above the reference mean. With a Z-score of 1.76 (96.1th percentile), this represents moderate enlargement; whole brain volume measures 1,087,360 mm³, 4.5% above the reference mean. With a Z-score of 0.54 (70.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,851 mm³, 4.2% above the reference mean. With a Z-score of 0.33 (62.9th percentile), this represents normal volume ; fusiform gyrus volume measures 19,738 mm³, 7.1% above the reference mean. With a Z-score of 0.64 (74.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,696 mm³, 15.4% above the reference mean. With a Z-score of 1.27 (89.8th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements show normal or above-average volumes in all regions, including the hippocampus, which is typically atrophied in Alzheimer's disease. The MMSE score of 30/30 indicates no cognitive impairment, and the absence of APOE4 alleles further reduces Alzheimer's risk.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
