  "img_finding": "Image findings: ventricular volume measures 18,180 mm³, 35.2% below the reference mean. With a Z-score of -0.81 (21.0th percentile), this represents normal volume ; hippocampal volume measures 7,449 mm³, 4.7% above the reference mean. With a Z-score of 0.43 (66.7th percentile), this represents normal volume ; entorhinal cortex volume measures 4,330 mm³, 17.9% above the reference mean. With a Z-score of 1.10 (86.4th percentile), this represents mild enlargement; fusiform gyrus volume measures 16,229 mm³, 4.6% below the reference mean. With a Z-score of -0.42 (33.7th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,907 mm³, 1.4% below the reference mean. With a Z-score of -0.12 (45.3th percentile), this represents normal volume . ",
  "text_data": "Age is 78.6 years. Gender is Female. Education: 12 years. Handedness: Right. Race: White. Medical history: Head, Eyes, Ears, Nose and Throat; Musculoskeletal; Endocrine-Metabolic; Gastrointestinal; Major Surgical Procedures. MMSE: 29.0. MoCA: 25.0. Logical Memory: 9.0. APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "Reasoning: The brain volume measurements are largely within normal ranges, with only mild enlargement noted in the entorhinal cortex. Cognitive scores (MMSE 29, MoCA 25) are borderline for MCI but still within normal limits for age. No APOE4 risk allele is present.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to borderline MoCA score but otherwise normal structural and genetic findings)",
