  "img_finding": "Image findings: ventricular volume measures 14,633 mm³, 34.5% below the reference mean. With a Z-score of -0.86 (19.4th percentile), this represents normal volume ; hippocampal volume measures 8,064 mm³, 4.9% above the reference mean. With a Z-score of 0.55 (71.0th percentile), this represents normal volume ; whole brain volume measures 1,103,610 mm³, 7.2% above the reference mean. With a Z-score of 0.90 (81.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,408 mm³, 12.5% below the reference mean. With a Z-score of -0.97 (16.7th percentile), this represents normal volume ; fusiform gyrus volume measures 18,289 mm³, 0.4% above the reference mean. With a Z-score of 0.05 (51.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,592 mm³, 15.0% above the reference mean. With a Z-score of 1.33 (90.8th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges or show mild enlargement, with no significant atrophy. Cognitive scores (MMSE 30, MoCA 28) are intact, and there is no APOE4 genetic risk factor.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
