  "img_finding": "Image findings: ventricular volume measures 30,266 mm³, 18.1% below the reference mean. With a Z-score of -0.49 (31.2th percentile), this represents normal volume ; whole brain volume measures 968,810 mm³, 4.4% above the reference mean. With a Z-score of 0.53 (70.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular and whole brain volumes are within normal ranges, and the MoCA score of 28.0 indicates no significant cognitive impairment. The absence of APOE4 and normal AV45 further reduce the likelihood of Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
