  "img_finding": "Image findings: ventricular volume measures 19,195 mm³, 36.1% below the reference mean. With a Z-score of -0.86 (19.6th percentile), this represents normal volume ; hippocampal volume measures 7,710 mm³, 3.9% below the reference mean. With a Z-score of -0.39 (34.7th percentile), this represents normal volume ; whole brain volume measures 1,165,100 mm³, 2.7% above the reference mean. With a Z-score of 0.38 (64.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,110 mm³, 3.6% below the reference mean. With a Z-score of -0.25 (40.2th percentile), this represents normal volume ; fusiform gyrus volume measures 19,502 mm³, 2.0% below the reference mean. With a Z-score of -0.17 (43.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,691 mm³, 5.7% above the reference mean. With a Z-score of 0.47 (68.1th 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. Cognitive scores (MMSE: 29, MoCA: 28) are also within normal limits, and the presence of one APOE4 allele does not override the absence of structural or functional deficits.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
