  "img_finding": "Image findings: ventricular volume measures 25,004 mm³, 11.9% above the reference mean. With a Z-score of 0.30 (61.7th percentile), this represents normal volume ; hippocampal volume measures 8,581 mm³, 11.7% above the reference mean. With a Z-score of 1.31 (90.5th percentile), this represents mild enlargement; whole brain volume measures 1,172,710 mm³, 13.9% above the reference mean. With a Z-score of 1.74 (95.9th percentile), this represents moderate enlargement; entorhinal cortex volume measures 4,381 mm³, 12.5% above the reference mean. With a Z-score of 0.97 (83.4th percentile), this represents normal volume ; fusiform gyrus volume measures 21,060 mm³, 15.7% above the reference mean. With a Z-score of 1.76 (96.1th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 21,385 mm³, 4.2% above the reference mean. With a Z-score of 0.37 (64.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are either normal or enlarged compared to reference means, with no atrophy observed. Cognitive scores (MMSE 30, MoCA 29) are in the normal range, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
