  "img_finding": "Image findings: ventricular volume measures 31,900 mm³, 13.7% below the reference mean. With a Z-score of -0.37 (35.6th percentile), this represents normal volume ; hippocampal volume measures 5,642 mm³, 13.1% below the reference mean. With a Z-score of -1.05 (14.6th percentile), this represents mild atrophy; whole brain volume measures 851,409 mm³, 8.3% below the reference mean. With a Z-score of -0.99 (16.0th percentile), this represents normal volume ; entorhinal cortex volume measures 2,948 mm³, 14.9% below the reference mean. With a Z-score of -0.80 (21.1th percentile), this represents normal volume ; fusiform gyrus volume measures 13,838 mm³, 14.1% below the reference mean. With a Z-score of -1.06 (14.5th percentile), this represents mild atrophy; middle temporal gyrus volume measures 17,839 mm³, 1.1% below the reference mean. With a Z-score of -0.09 (46.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The hippocampal and fusiform gyrus volumes show mild atrophy (Z-scores of -1.05 and -1.06, respectively), which are early indicators of neurodegeneration. Combined with an MMSE score of 22 (indicating mild cognitive impairment) and the presence of one APOE4 allele, this suggests cognitive decline beyond normal aging.  \n\nDiagnosis: MCI  \nConfidence: Medium",
