  "img_finding": "Image findings: ventricular volume measures 25,660 mm³, 33.4% below the reference mean. With a Z-score of -0.80 (21.2th percentile), this represents normal volume ; hippocampal volume measures 8,308 mm³, 9.9% above the reference mean. With a Z-score of 0.97 (83.3th percentile), this represents normal volume ; whole brain volume measures 1,156,120 mm³, 7.1% above the reference mean. With a Z-score of 0.92 (82.2th percentile), this represents normal volume ; entorhinal cortex volume measures 4,310 mm³, 5.1% above the reference mean. With a Z-score of 0.35 (63.5th percentile), this represents normal volume ; fusiform gyrus volume measures 16,398 mm³, 13.0% below the reference mean. With a Z-score of -1.10 (13.5th percentile), this represents mild atrophy; middle temporal gyrus volume measures 20,063 mm³, 6.0% below the reference mean. With a Z-score of -0.54 (29.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures show mostly normal values, with only mild atrophy in the fusiform gyrus. The MMSE score of 28 is within the normal range, and the absence of APOE4 alleles reduces genetic risk. No significant hippocampal or entorhinal cortex atrophy is present, which are key markers for Alzheimer's.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
