  "img_finding": "Image findings: ventricular volume measures 19,852 mm³, 33.9% below the reference mean. With a Z-score of -0.81 (21.0th percentile), this represents normal volume ; hippocampal volume measures 9,311 mm³, 16.0% above the reference mean. With a Z-score of 1.60 (94.5th percentile), this represents moderate enlargement; whole brain volume measures 1,278,260 mm³, 12.7% above the reference mean. With a Z-score of 1.79 (96.4th percentile), this represents moderate enlargement; entorhinal cortex volume measures 5,355 mm³, 25.6% above the reference mean. With a Z-score of 1.77 (96.2th percentile), this represents moderate enlargement; fusiform gyrus volume measures 22,895 mm³, 15.0% above the reference mean. With a Z-score of 1.25 (89.4th percentile), this represents mild enlargement; middle temporal gyrus volume measures 24,657 mm³, 10.0% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements show moderate to mild enlargement in key regions (hippocampus, whole brain, entorhinal cortex, fusiform gyrus) with no significant atrophy, and CSF biomarkers (Aβ, T-tau, P-tau) and amyloid PET (AV45) are normal. Cognitive scores (MMSE 27, MoCA 28) are within normal limits.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
