  "img_finding": "Image findings: ventricular volume measures 39,594 mm³, 2.8% above the reference mean. With a Z-score of 0.07 (52.7th percentile), this represents normal volume ; hippocampal volume measures 7,875 mm³, 4.2% above the reference mean. With a Z-score of 0.41 (65.8th percentile), this represents normal volume ; whole brain volume measures 1,019,480 mm³, 5.6% below the reference mean. With a Z-score of -0.72 (23.6th percentile), this represents normal volume ; entorhinal cortex volume measures 4,466 mm³, 8.9% above the reference mean. With a Z-score of 0.60 (72.7th percentile), this represents normal volume ; fusiform gyrus volume measures 18,454 mm³, 2.0% below the reference mean. With a Z-score of -0.17 (43.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,697 mm³, 6.4% above the reference mean. With a Z-score of 0.57 (71.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges based on Z-scores and percentiles. The MMSE score of 30 is optimal, and the absence of APOE4 alleles further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
