  "img_finding": "Image findings: ventricular volume measures 26,844 mm³, 20.2% above the reference mean. With a Z-score of 0.50 (69.3th percentile), this represents normal volume ; whole brain volume measures 855,949 mm³, 16.8% below the reference mean. With a Z-score of -2.10 (1.8th percentile), this represents significant atrophy; entorhinal cortex volume measures 2,783 mm³, 28.5% below the reference mean. With a Z-score of -2.21 (1.4th percentile), this represents significant atrophy; fusiform gyrus volume measures 15,244 mm³, 16.3% below the reference mean. With a Z-score of -1.83 (3.3th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 17,206 mm³, 16.1% below the reference mean. With a Z-score of -1.44 (7.6th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows significant atrophy in whole brain volume and entorhinal cortex, along with moderate to mild atrophy in the fusiform gyrus and middle temporal gyrus. The MMSE (23) and MoCA (21) scores indicate mild cognitive impairment, and the absence of APOE4 reduces but does not eliminate Alzheimer's risk.  \nDiagnosis: MCI (likely due to Alzheimer's pathology)  \nConfidence: Medium",
