  "img_finding": "Image findings: ventricular volume measures 33,670 mm³, 12.6% below the reference mean. With a Z-score of -0.30 (38.2th percentile), this represents normal volume ; hippocampal volume measures 7,551 mm³, 0.1% below the reference mean. With a Z-score of -0.01 (49.6th percentile), this represents normal volume ; whole brain volume measures 1,125,720 mm³, 4.3% above the reference mean. With a Z-score of 0.56 (71.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,358 mm³, 18.1% below the reference mean. With a Z-score of -1.23 (11.0th percentile), this represents mild atrophy; fusiform gyrus volume measures 19,941 mm³, 5.9% above the reference mean. With a Z-score of 0.50 (69.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,573 mm³, 1.1% above the reference mean.

  "gpt_diagnosis": "Reasoning: The brain volume measurements show mostly normal values, with only mild atrophy in the entorhinal cortex (Z-score -1.23, 11th percentile). Cognitive scores (MMSE 29, MoCA 29) are intact, and biomarkers (Aβ, T-tau, P-tau, AV45) are normal, ruling out significant Alzheimer's pathology.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
