  "img_finding": "Image findings: ventricular volume measures 15,290 mm³, 31.5% below the reference mean. With a Z-score of -0.79 (21.5th percentile), this represents normal volume ; hippocampal volume measures 7,685 mm³, 0.0% above the reference mean. With a Z-score of 0.00 (50.0th percentile), this represents normal volume ; whole brain volume measures 1,082,310 mm³, 5.2% above the reference mean. With a Z-score of 0.64 (74.0th percentile), this represents normal volume ; entorhinal cortex volume measures 5,311 mm³, 36.4% above the reference mean. With a Z-score of 2.82 (99.8th percentile), this represents significant enlargement; fusiform gyrus volume measures 17,274 mm³, 5.1% below the reference mean. With a Z-score of -0.58 (28.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,794 mm³, 1.3% above the reference mean. With a Z-score of 0.12 (54.7th percentile), this represents normal volume . ",
  "text_data": "Age is 62.1 years. Gender is Female. Education: 18 years. MMSE: 30.0. Logical Memory: 13.0. APOEε4 alleles: 0.0. Biomarker levels: Pittsburgh compound B: 1.17 SUVR (mild reduced). ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, fusiform gyrus, middle temporal gyrus) are within normal ranges or even above average (entorhinal cortex). The MMSE score of 30 is perfect, and there are no genetic risk factors (APOE4 negative). No structural or cognitive abnormalities suggest impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
