  "img_finding": "Image findings: ventricular volume measures 18,791 mm³, 15.9% below the reference mean. With a Z-score of -0.40 (34.6th percentile), this represents normal volume ; hippocampal volume measures 8,249 mm³, 7.3% above the reference mean. With a Z-score of 0.82 (79.5th percentile), this represents normal volume ; whole brain volume measures 1,106,330 mm³, 7.5% above the reference mean. With a Z-score of 0.93 (82.5th percentile), this represents normal volume ; entorhinal cortex volume measures 4,256 mm³, 9.3% above the reference mean. With a Z-score of 0.72 (76.5th percentile), this represents normal volume ; fusiform gyrus volume measures 18,922 mm³, 3.9% above the reference mean. With a Z-score of 0.44 (67.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,427 mm³, 14.2% above the reference mean. With a Z-score of 1.26 (89.6th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (hippocampus, entorhinal cortex, fusiform gyrus, etc.) are within or above the normal range, with no significant atrophy. Cognitive scores (MMSE 29, MoCA 28) are in the normal range, and APOE4 status (heterozygous) does not strongly indicate high risk alone.  \n\n**Diagnosis:** **CN (Cognitively Normal)**  \n**Confidence:** **High**",
