  "img_finding": "Image findings: ventricular volume measures 21,291 mm³, 14.3% above the reference mean. With a Z-score of 0.41 (65.9th percentile), this represents normal volume ; hippocampal volume measures 7,690 mm³, 1.5% below the reference mean. With a Z-score of -0.21 (41.7th percentile), this represents normal volume ; whole brain volume measures 1,059,290 mm³, 1.8% above the reference mean. With a Z-score of 0.22 (58.6th percentile), this represents normal volume ; entorhinal cortex volume measures 4,607 mm³, 24.7% above the reference mean. With a Z-score of 1.93 (97.3th percentile), this represents moderate enlargement; fusiform gyrus volume measures 21,097 mm³, 14.5% above the reference mean. With a Z-score of 1.31 (90.5th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,831 mm³, 3.4% below the reference mean. With a Z-score of -0.28 (38.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are largely within normal ranges, with only mild to moderate enlargement in the entorhinal cortex and fusiform gyrus, which are not typical of Alzheimer's pathology. Cognitive scores (MMSE 29, MoCA 27) are within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
