  "img_finding": "Image findings: ventricular volume measures 20,696 mm³, 26.3% below the reference mean. With a Z-score of -0.60 (27.4th percentile), this represents normal volume ; hippocampal volume measures 6,693 mm³, 5.9% below the reference mean. With a Z-score of -0.54 (29.3th percentile), this represents normal volume ; whole brain volume measures 932,165 mm³, 4.4% below the reference mean. With a Z-score of -0.55 (29.2th percentile), this represents normal volume ; entorhinal cortex volume measures 2,682 mm³, 27.0% below the reference mean. With a Z-score of -1.66 (4.9th percentile), this represents moderate atrophy; fusiform gyrus volume measures 15,138 mm³, 11.0% below the reference mean. With a Z-score of -1.00 (15.8th percentile), this represents mild atrophy; middle temporal gyrus volume measures 17,268 mm³, 9.9% below the reference mean. With a Z-score of -0.86 (19.5th percentile), this represents normal volume . ",
  "text_data": "Age is 75.4 years. Gender is Female. Education: 18 years. MMSE: 30.0. Laboratory findings: Neutrophils: 42.00 (significant reduced); Lymphocytes: 51.90 (profound elevated); Lymphocytes: 3.75 (profound elevated); Creatine Kinase: 211.00 (significant elevated). APOEε4 alleles: 1.0. ",

  "gpt_diagnosis": "Reasoning: The entorhinal cortex shows moderate atrophy (Z-score -1.66, 4.9th percentile), which is a key early marker for Alzheimer's pathology, while other regions (hippocampus, whole brain) are within normal ranges. The MMSE score of 30 is intact, and the presence of one APOE4 allele increases genetic risk but does not confirm impairment.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (Atrophy in the entorhinal cortex is concerning, but the absence of cognitive symptoms and normal hippocampal volume suggests no current impairment.)",
