  "img_finding": "Image findings: ventricular volume measures 20,599 mm³, 46.5% below the reference mean. With a Z-score of -1.11 (13.3th percentile), this represents mild atrophy; hippocampal volume measures 7,168 mm³, 5.2% below the reference mean. With a Z-score of -0.50 (30.7th percentile), this represents normal volume ; whole brain volume measures 1,139,000 mm³, 5.5% above the reference mean. With a Z-score of 0.72 (76.3th percentile), this represents normal volume ; entorhinal cortex volume measures 3,280 mm³, 20.0% below the reference mean. With a Z-score of -1.36 (8.7th percentile), this represents mild atrophy; fusiform gyrus volume measures 19,079 mm³, 1.3% above the reference mean. With a Z-score of 0.11 (54.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,252 mm³, 4.3% above the reference mean. With a Z-score of 0.38 (65.0th percentile), this represents normal volume . ",
  "text_data": "Age is 79.1 years. Gender is Male. Education: 10 years. Handedness: Right. Race: White. Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat. MMSE: 26.0. Logical Memory: 2.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The data shows mild atrophy in the ventricular volume and entorhinal cortex, while hippocampal and whole brain volumes are within normal ranges. The MMSE score of 26 is borderline but does not strongly indicate cognitive impairment, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
