  "img_finding": "Image findings: ventricular volume measures 49,502 mm³, 28.5% above the reference mean. With a Z-score of 0.68 (75.3th percentile), this represents normal volume ; whole brain volume measures 970,585 mm³, 10.1% below the reference mean. With a Z-score of -1.31 (9.5th percentile), this represents mild atrophy. ",
  "text_data": "Age is 72.1 years. Gender is Male. Education: 12 years. Handedness: Right. Race: White. Medical history: Psychiatric; Neurologic; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Endocrine-Metabolic; Hematopoietic-Lymphatic; Renal-Genitourinary; Allergies or Drug Sensitivities; Major Surgical Procedures. MMSE: 19.0. MoCA: 20.0. Logical Memory: 0.0. APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: AD.",
  "gpt_diagnosis": "Reasoning: The patient shows mild whole brain atrophy (Z-score -1.31, 9.5th percentile) and cognitive scores below typical thresholds (MMSE <24, MoCA <26), suggesting cognitive impairment. The presence of one APOE4 allele further supports a neurodegenerative process.  \nDiagnosis: Dementia  \nConfidence: Medium (Cognitive scores and atrophy align with dementia, but additional clinical context could strengthen certainty).",
