  "img_finding": "Image findings: ventricular volume measures 15,636 mm³, 30.0% below the reference mean. With a Z-score of -0.75 (22.6th percentile), this represents normal volume ; whole brain volume measures 1,127,350 mm³, 9.5% above the reference mean. With a Z-score of 1.19 (88.3th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,228 mm³, 8.6% above the reference mean. With a Z-score of 0.67 (74.8th percentile), this represents normal volume ; fusiform gyrus volume measures 20,478 mm³, 12.5% above the reference mean. With a Z-score of 1.40 (92.0th percentile), this represents mild enlargement; middle temporal gyrus volume measures 22,594 mm³, 10.1% above the reference mean. With a Z-score of 0.90 (81.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are largely within or above normal ranges, with no significant atrophy in key regions like the entorhinal cortex or middle temporal gyrus. Cognitive scores (MMSE 30, MoCA 26) are within normal limits, and amyloid PET (AV45) is normal, ruling out significant Alzheimer's pathology.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
