  "img_finding": "Image findings: ventricular volume measures 27,398 mm³, 28.9% below the reference mean. With a Z-score of -0.69 (24.5th percentile), this represents normal volume ; hippocampal volume measures 7,211 mm³, 4.6% below the reference mean. With a Z-score of -0.45 (32.7th percentile), this represents normal volume ; whole brain volume measures 1,100,800 mm³, 2.0% above the reference mean. With a Z-score of 0.26 (60.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,511 mm³, 14.4% below the reference mean. With a Z-score of -0.98 (16.5th percentile), this represents normal volume ; fusiform gyrus volume measures 17,128 mm³, 9.1% below the reference mean. With a Z-score of -0.77 (22.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,010 mm³, 1.5% below the reference mean. With a Z-score of -0.14 (44.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. The MMSE score of 28 is within the normal range (≥26), and there are no significant structural deficits suggestive of neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
