  "img_finding": "Image findings: ventricular volume measures 29,769 mm³, 22.7% below the reference mean. With a Z-score of -0.54 (29.3th percentile), this represents normal volume ; hippocampal volume measures 6,901 mm³, 8.7% below the reference mean. With a Z-score of -0.85 (19.8th percentile), this represents normal volume ; whole brain volume measures 997,202 mm³, 7.6% below the reference mean. With a Z-score of -0.99 (16.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,894 mm³, 5.0% below the reference mean. With a Z-score of -0.34 (36.6th percentile), this represents normal volume ; fusiform gyrus volume measures 17,173 mm³, 8.8% below the reference mean. With a Z-score of -0.75 (22.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,212 mm³, 10.0% below the reference mean. With a Z-score of -0.90 (18.5th percentile), this represents normal volume . ",

The MMSE score of 27 is within the normal range (≥26), and the presence of one APOE4 allele does not alone indicate cognitive impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
