  "img_finding": "Image findings: ventricular volume measures 15,094 mm³, 49.7% below the reference mean. With a Z-score of -1.18 (11.9th percentile), this represents mild atrophy; hippocampal volume measures 9,345 mm³, 16.4% above the reference mean. With a Z-score of 1.64 (95.0th percentile), this represents moderate enlargement; whole brain volume measures 1,139,000 mm³, 0.4% above the reference mean. With a Z-score of 0.06 (52.2th percentile), this represents normal volume ; entorhinal cortex volume measures 4,238 mm³, 0.6% below the reference mean. With a Z-score of -0.04 (48.4th percentile), this represents normal volume ; fusiform gyrus volume measures 19,520 mm³, 2.0% below the reference mean. With a Z-score of -0.16 (43.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,500 mm³, 0.4% above the reference mean. With a Z-score of 0.03 (51.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume data shows mild ventricular atrophy but otherwise normal or even enlarged hippocampal volume, with no significant atrophy in other key regions (entorhinal cortex, fusiform gyrus, middle temporal gyrus). Cognitive scores (MMSE 30, MoCA 26) are within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
