  "img_finding": "Image findings: ventricular volume measures 37,537 mm³, 68.0% above the reference mean. With a Z-score of 1.70 (95.6th percentile), this represents moderate enlargement; hippocampal volume measures 6,686 mm³, 13.0% below the reference mean. With a Z-score of -1.46 (7.2th percentile), this represents mild atrophy; whole brain volume measures 987,823 mm³, 4.0% below the reference mean. With a Z-score of -0.50 (30.9th percentile), this represents normal volume ; entorhinal cortex volume measures 3,877 mm³, 0.4% below the reference mean. With a Z-score of -0.03 (48.7th percentile), this represents normal volume ; fusiform gyrus volume measures 21,272 mm³, 16.8% above the reference mean. With a Z-score of 1.89 (97.1th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 20,366 mm³, 0.7% below the reference mean. With a Z-score of -0.07 (47.3th percentile), this represents normal volume . ",

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The imaging data shows moderate ventricular enlargement and mild hippocampal atrophy, both of which are associated with neurodegenerative changes. However, cognitive scores (MMSE 27, MoCA 25) remain within normal limits, and there is no significant whole-brain or entorhinal cortex atrophy.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (Cognitive scores are borderline, and imaging shows early neurodegenerative changes, but no clear functional impairment yet.)",
