  "img_finding": "Image findings: ventricular volume measures 66,692 mm³, 73.1% above the reference mean. With a Z-score of 1.75 (96.0th percentile), this represents moderate enlargement; hippocampal volume measures 6,545 mm³, 13.4% below the reference mean. With a Z-score of -1.31 (9.5th percentile), this represents mild atrophy; whole brain volume measures 1,104,890 mm³, 2.4% above the reference mean. With a Z-score of 0.31 (62.0th percentile), this represents normal volume ; entorhinal cortex volume measures 2,896 mm³, 29.4% below the reference mean. With a Z-score of -1.99 (2.3th percentile), this represents moderate atrophy; fusiform gyrus volume measures 17,590 mm³, 6.6% below the reference mean. With a Z-score of -0.56 (28.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,321 mm³, 4.6% above the reference mean. With a Z-score of 0.41 (66.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The imaging shows moderate ventricular enlargement and mild hippocampal atrophy, along with significant entorhinal cortex atrophy, which are indicative of early neurodegenerative changes. The MMSE score is normal (28/30), but the MoCA score (23/30) suggests mild cognitive impairment, particularly in executive function or visuospatial abilities. The absence of APOE4 reduces but does not eliminate Alzheimer’s risk.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (imaging supports neurodegeneration, but cognitive scores are borderline, and APOE4-negative status adds uncertainty).",
