  "img_finding": "Image findings: ventricular volume measures 14,268 mm³, 36.1% below the reference mean. With a Z-score of -0.90 (18.3th percentile), this represents normal volume ; hippocampal volume measures 7,113 mm³, 7.4% below the reference mean. With a Z-score of -0.83 (20.2th percentile), this represents normal volume ; whole brain volume measures 1,013,110 mm³, 1.6% below the reference mean. With a Z-score of -0.19 (42.3th percentile), this represents normal volume ; entorhinal cortex volume measures 4,340 mm³, 11.5% above the reference mean. With a Z-score of 0.89 (81.3th percentile), this represents normal volume ; fusiform gyrus volume measures 17,077 mm³, 6.2% below the reference mean. With a Z-score of -0.70 (24.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,270 mm³, 6.1% below the reference mean. With a Z-score of -0.54 (29.4th 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. Cognitive scores (MMSE 28, MoCA 26) are within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
