  "img_finding": "Image findings: ventricular volume measures 10,095 mm³, 64.0% below the reference mean. With a Z-score of -1.47 (7.1th percentile), this represents mild atrophy; hippocampal volume measures 7,557 mm³, 6.2% above the reference mean. With a Z-score of 0.57 (71.6th percentile), this represents normal volume ; whole brain volume measures 1,038,150 mm³, 6.5% above the reference mean. With a Z-score of 0.82 (79.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,027 mm³, 9.6% above the reference mean. With a Z-score of 0.59 (72.3th percentile), this represents normal volume ; fusiform gyrus volume measures 16,237 mm³, 4.6% below the reference mean. With a Z-score of -0.42 (33.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,112 mm³, 0.3% below the reference mean. With a Z-score of -0.03 (49.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain imaging shows mild ventricular atrophy but otherwise normal volumes in key regions (hippocampus, entorhinal cortex, fusiform gyrus, middle temporal gyrus). Cognitive testing (MMSE 30, MoCA 29) is intact, and there is no APOE4 genetic risk.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
