  "img_finding": "Image findings: ventricular volume measures 23,617 mm³, 5.7% above the reference mean. With a Z-score of 0.14 (55.7th percentile), this represents normal volume ; hippocampal volume measures 7,124 mm³, 7.3% below the reference mean. With a Z-score of -0.82 (20.7th percentile), this represents normal volume ; whole brain volume measures 982,625 mm³, 4.5% below the reference mean. With a Z-score of -0.56 (28.7th percentile), this represents normal volume ; entorhinal cortex volume measures 4,122 mm³, 5.9% above the reference mean. With a Z-score of 0.46 (67.6th percentile), this represents normal volume ; fusiform gyrus volume measures 15,815 mm³, 13.2% below the reference mean. With a Z-score of -1.48 (6.9th percentile), this represents mild atrophy; middle temporal gyrus volume measures 18,938 mm³, 7.7% below the reference mean. With a Z-score of -0.69 (24.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume data shows mostly normal measurements, with mild atrophy in the fusiform gyrus. Cognitive scores (MMSE 28, MoCA 25) are within normal ranges, and there is no APOE4 risk factor. The mild reduction in AV45 (amyloid PET) suggests some amyloid deposition but not strongly indicative of Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
