  "img_finding": "Image findings: ventricular volume measures 29,059 mm³, 3.2% below the reference mean. With a Z-score of -0.08 (47.0th percentile), this represents normal volume ; hippocampal volume measures 7,604 mm³, 5.3% below the reference mean. With a Z-score of -0.53 (29.9th percentile), this represents normal volume ; whole brain volume measures 1,112,030 mm³, 2.0% below the reference mean. With a Z-score of -0.28 (38.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,352 mm³, 2.1% above the reference mean. With a Z-score of 0.14 (55.8th percentile), this represents normal volume ; fusiform gyrus volume measures 17,199 mm³, 13.6% below the reference mean. With a Z-score of -1.13 (12.9th percentile), this represents mild atrophy; middle temporal gyrus volume measures 25,320 mm³, 13.0% above the reference mean. With a Z-score of 1.07 (85.7th percentile), this represents mild enlargement. ",
  "text_data": "Age is 65.4 years. Gender is Male. Education: 16 years. Handedness: Right. Race: White. MMSE: 30.0. MoCA: 28.0. Logical Memory: 10.0. APOEε4 alleles: 0.0. Biomarker levels: Flobetaben (FBB): 1.28 SUVR (profound elevated). ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements show mostly normal values, with mild atrophy in the fusiform gyrus and mild enlargement in the middle temporal gyrus. Cognitive scores (MMSE 30, MoCA 28) are within normal limits, and there is no APOE4 risk allele.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
