  "img_finding": "Image findings: ventricular volume measures 66,183 mm³, 79.0% above the reference mean. With a Z-score of 2.13 (98.4th percentile), this represents significant enlargement; hippocampal volume measures 5,719 mm³, 11.9% below the reference mean. With a Z-score of -0.96 (16.9th percentile), this represents normal volume ; whole brain volume measures 942,915 mm³, 1.6% above the reference mean. With a Z-score of 0.19 (57.6th percentile), this represents normal volume . ",

MMSE: 29.0. MoCA: 29.0. Logical Memory: 13.0. Laboratory findings: WBC: 10.96 (profound elevated); Neutrophils: 7.91 (profound elevated). APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "Reasoning: The ventricular volume is significantly enlarged (Z-score 2.13), which is often associated with neurodegenerative processes, but hippocampal and whole brain volumes are within normal ranges. Cognitive scores (MMSE and MoCA) are intact (29/30), and there is no APOE4 risk allele.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (ventricular enlargement raises suspicion, but normal cognition and other volumes suggest no significant impairment)",
