  "img_finding": "Image findings: ventricular volume measures 22,738 mm³, 41.0% below the reference mean. With a Z-score of -0.98 (16.3th percentile), this represents normal volume ; hippocampal volume measures 7,506 mm³, 0.7% below the reference mean. With a Z-score of -0.07 (47.3th percentile), this represents normal volume ; whole brain volume measures 1,044,100 mm³, 3.3% below the reference mean. With a Z-score of -0.42 (33.6th percentile), this represents normal volume ; entorhinal cortex volume measures 4,495 mm³, 9.6% above the reference mean. With a Z-score of 0.65 (74.3th percentile), this represents normal volume ; fusiform gyrus volume measures 16,899 mm³, 10.3% below the reference mean. With a Z-score of -0.88 (19.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,698 mm³, 1.7% above the reference mean. With a Z-score of 0.15 (56.0th percentile), this represents normal volume . ",
  "text_data": "Age is 75.0 years. Gender is Male. Education: 16 years. MMSE: 30.0. Laboratory findings: Basophils: 1.60 (significant elevated); Albumin: 4.70 (significant elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. The MMSE score of 30 is optimal, and there are no genetic risk factors (APOE4 negative).  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
