  "img_finding": "Image findings: ventricular volume measures 69,832 mm³, 81.3% above the reference mean. With a Z-score of 1.95 (97.4th percentile), this represents moderate enlargement; hippocampal volume measures 6,447 mm³, 14.7% below the reference mean. With a Z-score of -1.44 (7.6th percentile), this represents mild atrophy; whole brain volume measures 1,183,060 mm³, 9.6% above the reference mean. With a Z-score of 1.25 (89.4th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,999 mm³, 2.5% below the reference mean. With a Z-score of -0.17 (43.3th percentile), this represents normal volume ; fusiform gyrus volume measures 20,051 mm³, 6.4% above the reference mean. With a Z-score of 0.55 (70.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,290 mm³, 0.2% below the reference mean. With a Z-score of -0.02 (49.2th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The patient shows moderate ventricular enlargement and mild hippocampal atrophy, which are common in neurodegenerative conditions like Alzheimer's. However, the MMSE score of 27 is within the normal range, and other brain regions (entorhinal cortex, fusiform gyrus, middle temporal gyrus) are largely normal, suggesting no widespread atrophy. The absence of APOE4 also reduces Alzheimer's risk.  \nDiagnosis: MCI (Mild Cognitive Impairment)  \nConfidence: Medium",
