  "img_finding": "Image findings: ventricular volume measures 14,055 mm³, 49.9% below the reference mean. With a Z-score of -1.14 (12.6th percentile), this represents mild atrophy; hippocampal volume measures 7,341 mm³, 3.2% above the reference mean. With a Z-score of 0.29 (61.5th percentile), this represents normal volume ; whole brain volume measures 936,757 mm³, 3.9% below the reference mean. With a Z-score of -0.49 (31.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,705 mm³, 0.9% above the reference mean. With a Z-score of 0.05 (52.1th percentile), this represents normal volume ; fusiform gyrus volume measures 13,941 mm³, 18.1% below the reference mean. With a Z-score of -1.64 (5.0th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 18,643 mm³, 2.7% below the reference mean. With a Z-score of -0.24 (40.6th percentile), this represents normal volume . ",
  "text_data": "Age is 76.4 years. Gender is Female. Education: 13 years. MMSE: 28.0. Logical Memory: 7.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The imaging shows mild ventricular atrophy and moderate fusiform gyrus atrophy, but hippocampal, whole brain, entorhinal cortex, and middle temporal gyrus volumes are within normal ranges. The MMSE score of 28 is normal, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to isolated fusiform gyrus atrophy but otherwise normal clinical and imaging findings)",
