  "img_finding": "Image findings: ventricular volume measures 21,992 mm³, 21.6% below the reference mean. With a Z-score of -0.50 (31.0th percentile), this represents normal volume ; hippocampal volume measures 7,938 mm³, 11.6% above the reference mean. With a Z-score of 1.06 (85.6th percentile), this represents mild enlargement; whole brain volume measures 1,023,180 mm³, 5.0% above the reference mean. With a Z-score of 0.63 (73.5th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures (ventricular, hippocampal, and whole brain) are within normal ranges or even slightly above average, indicating no significant atrophy. Cognitive test scores (MMSE 30, MoCA 28) are in the normal range, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
