  "img_finding": "Image findings: ventricular volume measures 16,216 mm³, 27.4% below the reference mean. With a Z-score of -0.69 (24.6th percentile), this represents normal volume ; hippocampal volume measures 7,610 mm³, 1.0% below the reference mean. With a Z-score of -0.11 (45.7th percentile), this represents normal volume ; whole brain volume measures 1,127,880 mm³, 9.6% above the reference mean. With a Z-score of 1.19 (88.4th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,443 mm³, 11.6% below the reference mean. With a Z-score of -0.90 (18.5th percentile), this represents normal volume ; fusiform gyrus volume measures 18,430 mm³, 1.2% above the reference mean. With a Z-score of 0.14 (55.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,744 mm³, 6.0% above the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges or show mild enlargement, with no significant atrophy. Cognitive scores (MMSE, MoCA) are perfect, and biomarkers (Aβ, T-tau, P-tau, AV45) are normal, with no APOE4 risk alleles.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
