  "img_finding": "Image findings: ventricular volume measures 35,371 mm³, 26.0% above the reference mean. With a Z-score of 0.60 (72.4th percentile), this represents normal volume ; whole brain volume measures 1,115,870 mm³, 14.5% above the reference mean. With a Z-score of 1.82 (96.6th percentile), this represents moderate enlargement; entorhinal cortex volume measures 4,016 mm³, 9.3% above the reference mean. With a Z-score of 0.57 (71.7th percentile), this represents normal volume ; fusiform gyrus volume measures 20,032 mm³, 17.7% above the reference mean. With a Z-score of 1.61 (94.7th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 20,987 mm³, 9.5% above the reference mean. With a Z-score of 0.82 (79.5th percentile), this represents normal volume . ",

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain volumes are generally above the reference mean, with no significant atrophy in key regions like the entorhinal cortex or middle temporal gyrus. The MMSE (28/30) is normal, but the MoCA (24/30) suggests mild cognitive impairment (MCI), though APOE4-negative status lowers Alzheimer's risk.  \nDiagnosis: **MCI**  \nConfidence: **Medium** (MoCA indicates possible MCI, but structural imaging and APOE4 status do not strongly support progression to dementia.)",
