  "img_finding": "Image findings: ventricular volume measures 29,955 mm³, 0.2% below the reference mean. With a Z-score of -0.01 (49.8th percentile), this represents normal volume ; hippocampal volume measures 8,244 mm³, 2.7% above the reference mean. With a Z-score of 0.27 (60.6th percentile), this represents normal volume ; whole brain volume measures 1,176,010 mm³, 3.7% above the reference mean. With a Z-score of 0.52 (69.8th percentile), this represents normal volume ; entorhinal cortex volume measures 4,500 mm³, 5.6% above the reference mean. With a Z-score of 0.38 (65.0th percentile), this represents normal volume ; fusiform gyrus volume measures 17,988 mm³, 9.6% below the reference mean. With a Z-score of -0.80 (21.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,538 mm³, 3.9% below the reference mean. With a Z-score of -0.32 (37.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) fall within normal ranges, with no significant atrophy. MMSE score of 30 is optimal, and APOE4 status (heterozygous) does not indicate immediate risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
