  "img_finding": "Image findings: ventricular volume measures 19,644 mm³, 30.0% below the reference mean. With a Z-score of -0.69 (24.6th percentile), this represents normal volume ; hippocampal volume measures 7,944 mm³, 11.7% above the reference mean. With a Z-score of 1.07 (85.8th percentile), this represents mild enlargement; whole brain volume measures 1,022,380 mm³, 4.9% above the reference mean. With a Z-score of 0.62 (73.1th percentile), this represents normal volume ; entorhinal cortex volume measures 4,574 mm³, 24.5% above the reference mean. With a Z-score of 1.51 (93.4th percentile), this represents moderate enlargement; fusiform gyrus volume measures 16,303 mm³, 4.2% below the reference mean. With a Z-score of -0.38 (35.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,976 mm³, 1.0% below the reference mean. With a Z-score of -0.09 (46.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements show normal or above-average volumes in key regions (hippocampus, entorhinal cortex, whole brain), with no significant atrophy. The MMSE score of 29 is within the normal range, and the absence of APOE4 alleles reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
