  "img_finding": "Image findings: ventricular volume measures 25,163 mm³, 10.3% below the reference mean. With a Z-score of -0.24 (40.6th percentile), this represents normal volume ; hippocampal volume measures 7,168 mm³, 0.8% above the reference mean. With a Z-score of 0.07 (52.7th percentile), this represents normal volume ; whole brain volume measures 918,173 mm³, 5.8% below the reference mean. With a Z-score of -0.73 (23.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,534 mm³, 3.8% below the reference mean. With a Z-score of -0.23 (40.8th percentile), this represents normal volume ; fusiform gyrus volume measures 15,411 mm³, 9.4% below the reference mean. With a Z-score of -0.86 (19.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,553 mm³, 3.2% below the reference mean. With a Z-score of -0.28 (39.0th 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 27 is within the normal range (≥26), and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
