  "img_finding": "Image findings: ventricular volume measures 17,384 mm³, 38.1% below the reference mean. With a Z-score of -0.87 (19.2th percentile), this represents normal volume ; hippocampal volume measures 7,736 mm³, 8.7% above the reference mean. With a Z-score of 0.80 (78.8th percentile), this represents normal volume ; whole brain volume measures 1,053,110 mm³, 8.0% above the reference mean. With a Z-score of 1.01 (84.5th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,621 mm³, 1.4% below the reference mean. With a Z-score of -0.09 (46.5th percentile), this represents normal volume ; fusiform gyrus volume measures 21,173 mm³, 24.5% above the reference mean. With a Z-score of 2.23 (98.7th percentile), this represents significant enlargement; middle temporal gyrus volume measures 19,459 mm³, 1.5% above the reference mean. With a Z-score of 0.13 (55.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (hippocampal, ventricular, entorhinal cortex, fusiform gyrus, middle temporal gyrus, and whole brain) are within normal ranges or even enlarged, with no significant atrophy. Cognitive scores (MMSE 29, MoCA 28) are well within the normal range, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
