  "img_finding": "Image findings: ventricular volume measures 14,049 mm³, 37.1% below the reference mean. With a Z-score of -0.93 (17.7th percentile), this represents normal volume ; hippocampal volume measures 8,721 mm³, 13.5% above the reference mean. With a Z-score of 1.51 (93.5th percentile), this represents moderate enlargement; whole brain volume measures 1,083,770 mm³, 5.3% above the reference mean. With a Z-score of 0.66 (74.6th percentile), this represents normal volume ; entorhinal cortex volume measures 4,605 mm³, 18.3% above the reference mean. With a Z-score of 1.42 (92.2th percentile), this represents mild enlargement; fusiform gyrus volume measures 20,134 mm³, 10.6% above the reference mean. With a Z-score of 1.19 (88.3th percentile), this represents mild enlargement; middle temporal gyrus volume measures 22,241 mm³, 8.4% above the reference mean. With a Z-score of 0.75 (77.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures show normal or above-average volumes in all regions, including the hippocampus and entorhinal cortex, which are typically affected in Alzheimer's. The MMSE score of 28 is within the normal range, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
