  "img_finding": "Image findings: ventricular volume measures 20,384 mm³, 27.4% below the reference mean. With a Z-score of -0.63 (26.5th percentile), this represents normal volume ; hippocampal volume measures 8,080 mm³, 13.6% above the reference mean. With a Z-score of 1.24 (89.3th percentile), this represents mild enlargement; whole brain volume measures 949,924 mm³, 2.5% below the reference mean. With a Z-score of -0.32 (37.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,671 mm³, 0.1% below the reference mean. With a Z-score of -0.00 (49.9th percentile), this represents normal volume ; fusiform gyrus volume measures 19,454 mm³, 14.3% above the reference mean. With a Z-score of 1.31 (90.4th percentile), this represents mild enlargement; middle temporal gyrus volume measures 18,841 mm³, 1.7% below the reference mean. With a Z-score of -0.15 (44.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures are largely within normal ranges or even mildly enlarged (hippocampus, fusiform gyrus), with no significant atrophy. Cognitive scores (MMSE 30, MoCA 26) are normal or only slightly below average (MoCA), and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConf",
