  "img_finding": "Image findings: ventricular volume measures 22,388 mm³, 20.2% below the reference mean. With a Z-score of -0.46 (32.2th percentile), this represents normal volume ; hippocampal volume measures 7,422 mm³, 4.3% above the reference mean. With a Z-score of 0.40 (65.4th percentile), this represents normal volume ; whole brain volume measures 1,001,620 mm³, 2.8% above the reference mean. With a Z-score of 0.35 (63.6th percentile), this represents normal volume ; entorhinal cortex volume measures 4,086 mm³, 11.2% above the reference mean. With a Z-score of 0.69 (75.5th percentile), this represents normal volume ; fusiform gyrus volume measures 16,112 mm³, 5.3% below the reference mean. With a Z-score of -0.48 (31.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,764 mm³, 7.3% below the reference mean. With a Z-score of -0.64 (26.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. The MMSE score of 30 is optimal, and there is no APOE4 allele present, which reduces genetic risk for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
