  "img_finding": "Image findings: ventricular volume measures 22,133 mm³, 0.9% below the reference mean. With a Z-score of -0.02 (49.1th percentile), this represents normal volume ; whole brain volume measures 1,038,750 mm³, 0.9% above the reference mean. With a Z-score of 0.12 (54.6th percentile), this represents normal volume ; entorhinal cortex volume measures 4,196 mm³, 7.8% above the reference mean. With a Z-score of 0.60 (72.7th percentile), this represents normal volume ; fusiform gyrus volume measures 17,114 mm³, 6.0% below the reference mean. With a Z-score of -0.68 (24.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,750 mm³, 1.1% above the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volumes (ventricular, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are all within normal ranges based on Z-scores and percentiles. Cognitive screening scores (MMSE 29, MoCA 25) are also within normal limits for age, with no significant impairment noted. The absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
