  "img_finding": "Image findings: ventricular volume measures 18,663 mm³, 37.8% below the reference mean. With a Z-score of -0.90 (18.4th percentile), this represents normal volume ; hippocampal volume measures 8,905 mm³, 10.9% above the reference mean. With a Z-score of 1.09 (86.3th percentile), this represents mild enlargement; whole brain volume measures 1,175,840 mm³, 3.6% above the reference mean. With a Z-score of 0.52 (69.7th percentile), this represents normal volume ; entorhinal cortex volume measures 4,557 mm³, 6.9% above the reference mean. With a Z-score of 0.48 (68.3th percentile), this represents normal volume ; fusiform gyrus volume measures 19,480 mm³, 2.2% below the reference mean. With a Z-score of -0.18 (42.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,982 mm³, 7.0% above the reference mean. With a Z-score of 0.58 (71.8th percentile), this represents normal volume . ",
  "text_data": "Age is 67.0 years. Gender is Male. Education: 18 years. Handedness: Right. Race: White. Medical history: Cardiovascular; Gastrointestinal; Smoking. MMSE: 30.0. MoCA: 25.0. Logical Memory: 13.0. Laboratory findings: Total Bilirubin: 0.80 (significant elevated); Albumin: 4.90 (significant elevated). APOEε4 alleles: 1.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are largely within normal ranges or slightly above average, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. The MMSE score of 30 is normal, but the MoCA score of 25 suggests possible mild cognitive impairment (MCI), though not severe enough for dementia.  \n\n**Diagnosis:** MCI (Mild Cognitive Impairment)  \n**Confidence:** Medium (due to normal brain volumes but borderline MoCA score)",
