  "img_finding": "Image findings: ventricular volume measures 20,313 mm³, 27.6% below the reference mean. With a Z-score of -0.63 (26.3th percentile), this represents normal volume ; hippocampal volume measures 7,042 mm³, 1.0% below the reference mean. With a Z-score of -0.09 (46.3th percentile), this represents normal volume ; whole brain volume measures 1,006,640 mm³, 3.3% above the reference mean. With a Z-score of 0.41 (66.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,571 mm³, 2.8% below the reference mean. With a Z-score of -0.17 (43.2th percentile), this represents normal volume ; fusiform gyrus volume measures 15,792 mm³, 7.2% below the reference mean. With a Z-score of -0.65 (25.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,948 mm³, 1.2% below the reference mean. With a Z-score of -0.10 (46.0th percentile), this represents normal volume . ",

The MMSE score of 30/30 indicates no cognitive impairment, and the absence of APOE4 alleles further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
