  "img_finding": "Image findings: ventricular volume measures 37,700 mm³, 2.1% below the reference mean. With a Z-score of -0.05 (48.0th percentile), this represents normal volume ; hippocampal volume measures 7,009 mm³, 7.3% below the reference mean. With a Z-score of -0.71 (23.9th percentile), this represents normal volume ; whole brain volume measures 1,095,350 mm³, 1.5% above the reference mean. With a Z-score of 0.19 (57.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,867 mm³, 5.7% below the reference mean. With a Z-score of -0.39 (35.0th percentile), this represents normal volume ; fusiform gyrus volume measures 19,545 mm³, 3.8% above the reference mean. With a Z-score of 0.32 (62.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,018 mm³, 1.5% below the reference mean. With a Z-score of -0.14 (44.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive scores (MMSE 29, MoCA 25) are within normal limits for age, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
