  "img_finding": "Image findings: ventricular volume measures 26,195 mm³, 29.1% below the reference mean. With a Z-score of -0.79 (21.6th percentile), this represents normal volume ; hippocampal volume measures 7,565 mm³, 16.5% above the reference mean. With a Z-score of 1.32 (90.7th percentile), this represents mild enlargement; whole brain volume measures 930,185 mm³, 0.2% above the reference mean. With a Z-score of 0.03 (51.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,592 mm³, 3.7% above the reference mean. With a Z-score of 0.20 (58.0th percentile), this represents normal volume ; fusiform gyrus volume measures 18,587 mm³, 15.4% above the reference mean. With a Z-score of 1.16 (87.6th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,973 mm³, 10.8% above the reference mean. With a Z-score of 0.96 (83.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements show normal or mildly enlarged structures, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. Cognitive scores (MMSE 28, MoCA 25) are within normal limits for age, and amyloid imaging (AV45) is normal, making neurodegenerative dementia unlikely.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
