  "img_finding": "Image findings: ventricular volume measures 23,250 mm³, 17.2% below the reference mean. With a Z-score of -0.39 (34.7th percentile), this represents normal volume ; hippocampal volume measures 7,044 mm³, 1.0% below the reference mean. With a Z-score of -0.09 (46.4th percentile), this represents normal volume ; whole brain volume measures 1,051,700 mm³, 7.9% above the reference mean. With a Z-score of 1.00 (84.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,568 mm³, 2.9% below the reference mean. With a Z-score of -0.18 (43.0th percentile), this represents normal volume ; fusiform gyrus volume measures 19,843 mm³, 16.6% above the reference mean. With a Z-score of 1.51 (93.5th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 23,068 mm³, 20.3% above the reference mean. With a Z-score of 1.77 (96.1th percentile), this represents moderate enlargement. ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements (ventricular, hippocampal, whole brain, entorhinal cortex) are within normal ranges, with some regions (fusiform gyrus, middle temporal gyrus) showing moderate enlargement. The MMSE score of 29 is normal, but the MoCA score of 24 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces Alzheimer's risk.  \nDiagnosis: MCI  \nConfidence: Medium",
