  "img_finding": "Image findings: ventricular volume measures 26,730 mm³, 4.8% below the reference mean. With a Z-score of -0.11 (45.7th percentile), this represents normal volume ; hippocampal volume measures 7,157 mm³, 0.6% above the reference mean. With a Z-score of 0.05 (52.2th percentile), this represents normal volume ; whole brain volume measures 1,042,770 mm³, 7.0% above the reference mean. With a Z-score of 0.88 (81.1th percentile), this represents normal volume ; entorhinal cortex volume measures 4,209 mm³, 14.6% above the reference mean. With a Z-score of 0.90 (81.5th percentile), this represents normal volume ; fusiform gyrus volume measures 16,646 mm³, 2.2% below the reference mean. With a Z-score of -0.20 (42.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,136 mm³, 5.4% below the reference mean. With a Z-score of -0.47 (32.0th percentile), this represents normal volume . ",

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