  "img_finding": "Image findings: ventricular volume measures 116,258 mm³, 147.3% above the reference mean. With a Z-score of 4.28 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 6,550 mm³, 6.0% below the reference mean. With a Z-score of -0.52 (30.2th percentile), this represents normal volume ; whole brain volume measures 1,177,840 mm³, 14.4% above the reference mean. With a Z-score of 1.89 (97.1th percentile), this represents moderate enlargement; entorhinal cortex volume measures 3,390 mm³, 14.6% below the reference mean. With a Z-score of -0.95 (17.0th percentile), this represents normal volume ; fusiform gyrus volume measures 15,208 mm³, 15.8% below the reference mean. With a Z-score of -1.37 (8.5th percentile), this represents mild atrophy; middle temporal gyrus volume measures 18,433 mm³, 8.6% below the reference mean. With a Z-score of -0.77 (22.0th percentile), this represents normal volume . ",
  "text_data": "Age is 82.7 years. Gender is Male. Education: 20 years. MMSE: 28.0. Logical Memory: 15.0. Laboratory findings: Lymphocytes: 46.20 (significant elevated); WBC: 9.30 (significant elevated); Lymphocytes: 4.29 (profound elevated). APOEε4 alleles: 0.0. ",
  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The patient shows profound ventricular enlargement (Z-score 4.28) and mild fusiform gyrus atrophy (Z-score -1.37), but hippocampal and entorhinal volumes are within normal limits. The MMSE score of 28 is normal, and there is no APOE4 risk allele. The ventricular enlargement may suggest some neurodegenerative changes, but cognitive performance remains intact.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to significant ventricular enlargement but preserved cognition and no other strong atrophy markers)",
