  "img_finding": "Image findings: ventricular volume measures 35,634 mm³, 7.5% below the reference mean. With a Z-score of -0.18 (42.9th percentile), this represents normal volume ; hippocampal volume measures 8,618 mm³, 14.0% above the reference mean. With a Z-score of 1.37 (91.4th percentile), this represents mild enlargement; whole brain volume measures 1,171,650 mm³, 8.5% above the reference mean. With a Z-score of 1.11 (86.6th percentile), this represents mild enlargement; entorhinal cortex volume measures 5,200 mm³, 26.8% above the reference mean. With a Z-score of 1.82 (96.5th percentile), this represents moderate enlargement; fusiform gyrus volume measures 22,783 mm³, 20.9% above the reference mean. With a Z-score of 1.78 (96.3th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 20,895 mm³, 2.1% below the reference mean. With a Z-score of -0.19 (42.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements show normal to above-normal volumes across all regions, including the hippocampus and entorhinal cortex, which are typically affected in Alzheimer's. Cognitive scores (MMSE 28, MoCA 27) are within the normal range, and the absence of APOE4 further reduces Alzheimer's risk.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
