  "img_finding": "Image findings: ventricular volume measures 39,534 mm³, 40.9% above the reference mean. With a Z-score of 0.94 (82.5th percentile), this represents normal volume ; hippocampal volume measures 7,674 mm³, 7.9% above the reference mean. With a Z-score of 0.72 (76.5th percentile), this represents normal volume ; whole brain volume measures 1,050,130 mm³, 7.7% above the reference mean. With a Z-score of 0.97 (83.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,841 mm³, 4.6% above the reference mean. With a Z-score of 0.28 (61.1th percentile), this represents normal volume ; fusiform gyrus volume measures 17,825 mm³, 4.8% above the reference mean. With a Z-score of 0.43 (66.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,992 mm³, 14.7% above the reference mean. With a Z-score of 1.28 (89.9th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges or mildly enlarged, with no significant atrophy. Cognitive scores (MMSE 30, MoCA 29) are intact, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
