  "img_finding": "Image findings: ventricular volume measures 27,081 mm³, 26.7% below the reference mean. With a Z-score of -0.72 (23.5th percentile), this represents normal volume ; hippocampal volume measures 6,832 mm³, 5.2% above the reference mean. With a Z-score of 0.42 (66.1th percentile), this represents normal volume ; whole brain volume measures 975,162 mm³, 5.1% above the reference mean. With a Z-score of 0.61 (72.8th percentile), this represents normal volume ; entorhinal cortex volume measures 4,065 mm³, 17.4% above the reference mean. With a Z-score of 0.94 (82.6th percentile), this represents normal volume ; fusiform gyrus volume measures 16,801 mm³, 4.3% above the reference mean. With a Z-score of 0.32 (62.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,779 mm³, 9.7% above the reference mean.

The MMSE score of 29.0 is within the normal range (≥26), and the absence of APOE4 alleles further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
