  "img_finding": "Image findings: ventricular volume measures 26,697 mm³, 4.9% below the reference mean. With a Z-score of -0.11 (45.5th percentile), this represents normal volume ; hippocampal volume measures 8,395 mm³, 18.0% above the reference mean. With a Z-score of 1.65 (95.1th percentile), this represents moderate enlargement; whole brain volume measures 1,069,970 mm³, 9.8% above the reference mean. With a Z-score of 1.23 (89.1th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,074 mm³, 10.9% above the reference mean. With a Z-score of 0.67 (74.9th percentile), this represents normal volume ; fusiform gyrus volume measures 19,589 mm³, 15.1% above the reference mean. With a Z-score of 1.38 (91.6th percentile), this represents mild enlargement; middle temporal gyrus volume measures 17,809 mm³, 7.1% below the reference mean. With a Z-score of -0.62 (26.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures show no significant atrophy in key regions typically affected in Alzheimer's disease (e.g., hippocampus is enlarged, not reduced). Cognitive scores (MMSE, MoCA) are within normal range, and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
