  "img_finding": "Image findings: ventricular volume measures 6,451 mm³, 71.1% below the reference mean. With a Z-score of -1.78 (3.8th percentile), this represents moderate atrophy; hippocampal volume measures 7,006 mm³, 8.8% below the reference mean. With a Z-score of -0.99 (16.1th percentile), this represents normal volume ; whole brain volume measures 910,646 mm³, 11.5% below the reference mean. With a Z-score of -1.43 (7.6th percentile), this represents mild atrophy; entorhinal cortex volume measures 3,248 mm³, 16.6% below the reference mean. With a Z-score of -1.28 (10.0th percentile), this represents mild atrophy; fusiform gyrus volume measures 16,421 mm³, 9.8% below the reference mean. With a Z-score of -1.11 (13.4th percentile), this represents mild atrophy; middle temporal gyrus volume measures 16,366 mm³, 20.2% below the reference mean. With a Z-score of -1.80 (3.6th percentile), this represents moderate atrophy. ",
  "text_data": "Age is 62.2 years. Gender is Female. Education: 13 years. MMSE: 30.0. MoCA: 30.0. Logical Memory: 18.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The imaging data shows moderate atrophy in the ventricles and middle temporal gyrus, with mild atrophy in the whole brain, entorhinal cortex, and fusiform gyrus. However, cognitive scores (MMSE, MoCA) are intact, and there is no APOE4 risk allele.  \n**Diagnosis:** **CN (Cognitively Normal)**  \n**Confidence:** **Medium** (Atrophy patterns are concerning, but cognitive performance is preserved, and genetic risk is low.)",
