  "img_finding": "Image findings: ventricular volume measures 42,717 mm³, 91.2% above the reference mean. With a Z-score of 2.28 (98.9th percentile), this represents significant enlargement; hippocampal volume measures 6,997 mm³, 8.9% below the reference mean. With a Z-score of -1.00 (15.8th percentile), this represents mild atrophy; whole brain volume measures 1,031,620 mm³, 0.2% above the reference mean. With a Z-score of 0.03 (51.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,976 mm³, 2.1% above the reference mean. With a Z-score of 0.17 (56.6th percentile), this represents normal volume ; fusiform gyrus volume measures 15,858 mm³, 12.9% below the reference mean. With a Z-score of -1.45 (7.3th percentile), this represents mild atrophy; middle temporal gyrus volume measures 22,057 mm³, 7.5% above the reference mean. With a Z-score of 0.67 (74.7th percentile), this represents normal volume . ",
  "text_data": "Age is 60.1 years. Gender is Female. Education: 16 years. MMSE: 29.0. MoCA: 22.0. Logical Memory: 6.0. APOEε4 alleles: 0.0. Biomarker levels: Flobetaben (FBB): 0.98 SUVR (normal ). ",

  "gpt_diagnosis": "**Reasoning:** The data shows significant ventricular enlargement (Z-score 2.28) and mild hippocampal atrophy (Z-score -1.00), along with mild fusiform gyrus atrophy (Z-score -1.45). The MMSE is normal (29/30), but the MoCA (22/30) suggests mild cognitive impairment. No APOE4 alleles reduce genetic risk.  \n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (due to conflicting MMSE/MoCA scores but clear structural changes)",
