  "img_finding": "Image findings: ventricular volume measures 23,506 mm³, 39.0% below the reference mean. With a Z-score of -0.93 (17.5th percentile), this represents normal volume ; hippocampal volume measures 7,214 mm³, 4.6% below the reference mean. With a Z-score of -0.45 (32.8th percentile), this represents normal volume ; whole brain volume measures 1,104,960 mm³, 2.4% above the reference mean. With a Z-score of 0.31 (62.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,691 mm³, 10.0% below the reference mean. With a Z-score of -0.68 (24.9th percentile), this represents normal volume ; fusiform gyrus volume measures 18,580 mm³, 1.4% below the reference mean. With a Z-score of -0.12 (45.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,027 mm³, 3.2% above the reference mean. With a Z-score of 0.29 (61.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (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 29 is within the normal range (≥26), and the absence of APOE4 alleles further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
