  "img_finding": "Image findings: ventricular volume measures 29,050 mm³, 24.6% below the reference mean. With a Z-score of -0.59 (27.8th percentile), this represents normal volume ; hippocampal volume measures 7,087 mm³, 6.2% below the reference mean. With a Z-score of -0.61 (27.1th percentile), this represents normal volume ; whole brain volume measures 1,054,140 mm³, 2.3% below the reference mean. With a Z-score of -0.30 (38.1th percentile), this represents normal volume ; entorhinal cortex volume measures 5,326 mm³, 29.9% above the reference mean. With a Z-score of 2.03 (97.9th percentile), this represents significant enlargement; fusiform gyrus volume measures 18,554 mm³, 1.5% below the reference mean. With a Z-score of -0.13 (44.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,330 mm³, 4.7% below the reference mean. With a Z-score of -0.43 (33.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements are largely within normal ranges, with the exception of the entorhinal cortex, which shows significant enlargement (Z-score 2.03, 97.9th percentile). The MMSE score of 30 is normal, but the MoCA score of 23 suggests mild cognitive impairment (MCI). The absence of APOE4 reduces genetic predisposition to Alzheimer's.  \nDiagnosis: MCI  \nConfidence: Medium",
