  "img_finding": "Image findings: ventricular volume measures 31,301 mm³, 4.2% above the reference mean. With a Z-score of 0.10 (54.0th percentile), this represents normal volume ; hippocampal volume measures 8,836 mm³, 10.1% above the reference mean. With a Z-score of 1.01 (84.3th percentile), this represents mild enlargement; whole brain volume measures 1,197,270 mm³, 5.5% above the reference mean. With a Z-score of 0.78 (78.3th percentile), this represents normal volume ; entorhinal cortex volume measures 4,353 mm³, 2.1% above the reference mean. With a Z-score of 0.15 (55.8th percentile), this represents normal volume ; fusiform gyrus volume measures 22,386 mm³, 12.4% above the reference mean. With a Z-score of 1.03 (85.0th percentile), this represents mild enlargement; middle temporal gyrus volume measures 22,079 mm³, 1.5% below the reference mean. With a Z-score of -0.12 (45.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measures are largely within normal ranges or mildly enlarged, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. Cognitive scores (MMSE 30, MoCA 25) are normal to borderline, and biomarkers (tau, amyloid) are unremarkable.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
