  "img_finding": "Image findings: ventricular volume measures 83,825 mm³, 78.3% above the reference mean. With a Z-score of 2.27 (98.9th percentile), this represents significant enlargement; whole brain volume measures 1,181,150 mm³, 14.8% above the reference mean. With a Z-score of 1.94 (97.4th percentile), this represents moderate enlargement. ",
  "text_data": "Age is 89.3 years. Gender is Male. Education: 13 years. Handedness: Left. Race: White. Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Respiratory; Endocrine-Metabolic; Gastrointestinal; Renal-Genitourinary. MMSE: 26.0. Logical Memory: 4.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 2.27, 98.9th percentile), which is often associated with brain atrophy and neurodegenerative processes. However, the whole brain volume is also moderately enlarged (Z-score 1.94, 97.4th percentile), which is unusual for typical Alzheimer's progression. The MMSE score of 26 is within the normal range, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to conflicting volumetric findings despite normal MMSE and no APOE4 risk)",
