  "img_finding": "Image findings: ventricular volume measures 19,248 mm³, 31.4% below the reference mean. With a Z-score of -0.72 (23.6th percentile), this represents normal volume ; whole brain volume measures 876,843 mm³, 10.0% below the reference mean. With a Z-score of -1.26 (10.3th percentile), this represents mild atrophy. ",
  "text_data": "Age is 77.6 years. Gender is Female. Education: 16 years. MMSE: 22.0. Logical Memory: 1.0. APOEε4 alleles: 0.0. Biomarker levels: Pittsburgh compound B: 1.56 SUVR (normal ). ",
