  "img_finding": "Image findings: ventricular volume measures 42,607 mm³, 41.9% above the reference mean. With a Z-score of 1.00 (84.0th percentile), this represents normal volume ; hippocampal volume measures 8,024 mm³, 0.0% below the reference mean. With a Z-score of -0.00 (49.8th percentile), this represents normal volume ; whole brain volume measures 1,158,160 mm³, 2.1% above the reference mean. With a Z-score of 0.29 (61.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,929 mm³, 7.8% below the reference mean. With a Z-score of -0.54 (29.4th percentile), this represents normal volume ; fusiform gyrus volume measures 14,645 mm³, 26.4% below the reference mean. With a Z-score of -2.20 (1.4th percentile), this represents significant atrophy; middle temporal gyrus volume measures 18,770 mm³, 16.2% below the reference mean. With a Z-score of -1.34 (9.0th percentile), this represents mild atrophy. ",
  "text_data": "Age is 68.9 years. Gender is Male. Education: 20 years. MMSE: 30.0. Laboratory findings: Thyroid Stim. Hormone: 4.43 (significant elevated); Total Bilirubin: 0.90 (significant elevated); GGT: 125.00 (profound elevated); ALT (SGPT): 38.00 (significant elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** The fusiform gyrus shows significant atrophy (Z-score -2.20, 1.4th percentile), and the middle temporal gyrus shows mild atrophy (Z-score -1.34, 9.0th percentile), which are concerning for neurodegenerative changes. However, hippocampal and whole brain volumes are normal, and the MMSE score is perfect (30/30), with no APOE4 risk alleles.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)** (due to focal atrophy in temporal regions despite intact global cognition)  \n**Confidence:** **Medium** (structural changes are present, but clinical symptoms are absent, making progression uncertain).",
