  "img_finding": "Image findings: ventricular volume measures 36,101 mm³, 20.2% above the reference mean. With a Z-score of 0.48 (68.5th percentile), this represents normal volume ; hippocampal volume measures 6,910 mm³, 13.9% below the reference mean. With a Z-score of -1.39 (8.2th percentile), this represents mild atrophy; whole brain volume measures 1,049,280 mm³, 7.5% below the reference mean. With a Z-score of -1.06 (14.4th percentile), this represents mild atrophy; entorhinal cortex volume measures 3,994 mm³, 6.3% below the reference mean. With a Z-score of -0.44 (33.1th percentile), this represents normal volume ; fusiform gyrus volume measures 23,342 mm³, 17.2% above the reference mean. With a Z-score of 1.43 (92.4th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,062 mm³, 14.9% below the reference mean. With a Z-score of -1.23 (10.9th percentile), this represents mild atrophy. ",
  "text_data": "Age is 61.6 years. Gender is Male. Education: 19 years. MMSE: 30.0. MoCA: 29.0. Logical Memory: 11.0. Laboratory findings: Serum Glucose: 134.00 (significant elevated); Creatine Kinase: 322.00 (profound elevated); Calcium (EDTA): 8.90 (significant reduced). APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The hippocampal and middle temporal gyrus volumes show mild atrophy (Z-scores -1.39 and -1.23, respectively), which are concerning for early neurodegenerative changes. However, cognitive scores (MMSE 30, MoCA 29) are intact, and entorhinal cortex volume is normal, suggesting no significant functional impairment yet.  \nDiagnosis: **MCI** (Mild Cognitive Impairment)  \nConfidence: **Medium** (Structural changes are present, but cognitive performance remains normal, making early MCI more likely than dementia.)",
