  "img_finding": "Image findings: ventricular volume measures 11,707 mm³, 58.3% below the reference mean. With a Z-score of -1.33 (9.1th percentile), this represents mild atrophy; hippocampal volume measures 7,149 mm³, 0.5% above the reference mean. With a Z-score of 0.04 (51.8th percentile), this represents normal volume ; whole brain volume measures 940,037 mm³, 3.6% below the reference mean. With a Z-score of -0.45 (32.7th percentile), this represents normal volume ; entorhinal cortex volume measures 3,374 mm³, 8.1% below the reference mean. With a Z-score of -0.50 (30.9th percentile), this represents normal volume ; fusiform gyrus volume measures 18,248 mm³, 7.3% above the reference mean. With a Z-score of 0.66 (74.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 16,920 mm³, 11.7% below the reference mean. With a Z-score of -1.02 (15.4th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "**Reasoning:** The brain imaging shows mild ventricular and middle temporal gyrus atrophy, but hippocampal, whole brain, entorhinal cortex, and fusiform gyrus volumes are within normal ranges. Cognitive testing (MMSE 27, MoCA 29) is intact, and there is no APOE4 genetic risk.  \n\n**Diagnosis:** **CN (Cognitively Normal)**  \n**Confidence:** **High**",
