  "img_finding": "Image findings: ventricular volume measures 38,072 mm³, 35.6% above the reference mean. With a Z-score of 0.82 (79.3th percentile), this represents normal volume ; hippocampal volume measures 6,282 mm³, 11.7% below the reference mean. With a Z-score of -1.07 (14.2th percentile), this represents mild atrophy; whole brain volume measures 847,640 mm³, 13.0% below the reference mean. With a Z-score of -1.64 (5.0th percentile), this represents moderate atrophy; entorhinal cortex volume measures 3,845 mm³, 4.7% above the reference mean. With a Z-score of 0.29 (61.3th percentile), this represents normal volume ; fusiform gyrus volume measures 16,878 mm³, 0.8% below the reference mean. With a Z-score of -0.07 (47.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 15,868 mm³, 17.2% below the reference mean. With a Z-score of -1.50 (6.7th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The patient shows mild hippocampal atrophy (Z-score -1.07) and moderate whole brain atrophy (Z-score -1.64), along with mild middle temporal gyrus atrophy (Z-score -1.50), which are suggestive of neurodegenerative changes. However, cognitive scores (MMSE 29, MoCA 24) are relatively preserved, with no significant impairment in daily functioning reported.  \nDiagnosis: Mild Cognitive Impairment (MCI)  \nConfidence: Medium (structural changes are present, but cognitive scores are borderline normal, and APOE4-negative status reduces Alzheimer's risk",
