  "img_finding": "Image findings: ventricular volume measures 36,867 mm³, 0.3% below the reference mean. With a Z-score of -0.01 (49.7th percentile), this represents normal volume ; hippocampal volume measures 6,596 mm³, 1.6% above the reference mean. With a Z-score of 0.12 (55.0th percentile), this represents normal volume ; whole brain volume measures 1,083,140 mm³, 16.7% above the reference mean. With a Z-score of 2.00 (97.7th percentile), this represents significant enlargement. ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements (ventricular, hippocampal, and whole brain) are within normal or above-normal ranges, with no significant atrophy. Cognitive testing shows a high MMSE (29/30) but a borderline MoCA (23/30), which may suggest mild cognitive concerns. Biomarkers (T-tau, P-tau, AV45) are normal, and there is no APOE4 risk allele.  \nDiagnosis: **CN (Cognitively Normal)**  \nConfidence: **Medium** (due to the borderline MoCA score, though other markers are reassuring)",
