  "img_finding": "Image findings: ventricular volume measures 43,081 mm³, 11.8% above the reference mean. With a Z-score of 0.28 (61.2th percentile), this represents normal volume ; hippocampal volume measures 7,384 mm³, 2.3% below the reference mean. With a Z-score of -0.23 (41.1th percentile), this represents normal volume ; whole brain volume measures 1,233,380 mm³, 14.3% above the reference mean. With a Z-score of 1.85 (96.8th percentile), this represents moderate enlargement; entorhinal cortex volume measures 4,242 mm³, 3.4% above the reference mean. With a Z-score of 0.23 (59.2th percentile), this represents normal volume ; fusiform gyrus volume measures 19,920 mm³, 5.7% above the reference mean. With a Z-score of 0.49 (68.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,487 mm³, 10.1% above the reference mean. With a Z-score of 0.90 (81.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** All brain volumes (hippocampal, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges or slightly above, with no significant atrophy. Cognitive scores (MMSE 30, MoCA 29) are intact, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
