  "img_finding": "Image findings: ventricular volume measures 17,585 mm³, 54.3% below the reference mean. With a Z-score of -1.30 (9.6th percentile), this represents mild atrophy; hippocampal volume measures 7,616 mm³, 0.8% above the reference mean. With a Z-score of 0.07 (52.9th percentile), this represents normal volume ; whole brain volume measures 1,018,370 mm³, 5.7% below the reference mean. With a Z-score of -0.73 (23.1th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The patient shows mild ventricular atrophy but normal hippocampal and whole brain volumes, suggesting no significant neurodegeneration. Cognitive scores (MMSE 30, MoCA 25) are within normal limits, and biomarkers (T-tau, P-tau, AV45) are unremarkable.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
