  "img_finding": "Image findings: ventricular volume measures 19,198 mm³, 14.1% below the reference mean. With a Z-score of -0.35 (36.3th percentile), this represents normal volume ; hippocampal volume measures 7,149 mm³, 7.0% below the reference mean. With a Z-score of -0.78 (21.7th percentile), this represents normal volume ; whole brain volume measures 900,771 mm³, 12.5% below the reference mean. With a Z-score of -1.55 (6.0th percentile), this represents moderate atrophy; entorhinal cortex volume measures 3,859 mm³, 0.9% below the reference mean. With a Z-score of -0.07 (47.3th percentile), this represents normal volume ; fusiform gyrus volume measures 16,457 mm³, 9.6% below the reference mean. With a Z-score of -1.08 (13.9th percentile), this represents mild atrophy; middle temporal gyrus volume measures 20,570 mm³, 0.2% above the reference mean. With a Z-score of 0.02 (50.9th percentile), this represents normal volume . ",
  "text_data": "Age is 65.6 years. Gender is Female. Education: 12 years. MMSE: 30.0. Logical Memory: 11.0. Laboratory findings: Eosinophils: 0.34 (significant elevated); Basophils: 0.10 (significant elevated); WBC: 13.69 (profound elevated); Neutrophils: 10.17 (profound elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The brain imaging shows moderate whole brain atrophy and mild fusiform gyrus atrophy, but hippocampal and other regional volumes are within normal ranges. The MMSE score of 30 is intact, and there are no APOE4 risk alleles.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to the presence of some atrophy but no cognitive or genetic risk factors)",
