  "img_finding": "Image findings: ventricular volume measures 14,365 mm³, 35.7% below the reference mean. With a Z-score of -0.89 (18.6th percentile), this represents normal volume ; hippocampal volume measures 6,944 mm³, 9.6% below the reference mean. With a Z-score of -1.08 (14.0th percentile), this represents mild atrophy; whole brain volume measures 933,151 mm³, 9.3% below the reference mean. With a Z-score of -1.16 (12.3th percentile), this represents mild atrophy; entorhinal cortex volume measures 3,550 mm³, 8.8% below the reference mean. With a Z-score of -0.68 (24.7th percentile), this represents normal volume ; fusiform gyrus volume measures 16,228 mm³, 10.9% below the reference mean. With a Z-score of -1.23 (11.0th percentile), this represents mild atrophy; middle temporal gyrus volume measures 21,741 mm³, 6.0% above the reference mean. With a Z-score of 0.53 (70.2th percentile), this represents normal volume . ",
  "text_data": "Age is 64.2 years. Gender is Female. Education: 18 years. Handedness: Right. Race: Black or African American. MMSE: 30.0. MoCA: 22.0. Logical Memory: 8.0. Biomarker levels: Flobetaben (FBB): 1.00 SUVR (normal ). ",

  "gpt_diagnosis": "**Reasoning:** The imaging data shows mild atrophy in the hippocampus, whole brain, and fusiform gyrus, while other regions (ventricular, entorhinal cortex, middle temporal gyrus) are within normal ranges. The MoCA score of 22 suggests mild cognitive impairment, while the MMSE of 30 is normal, indicating possible early-stage cognitive decline.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (due to conflicting MMSE/MoCA scores but structural atrophy supporting MCI)",
