  "img_finding": "Image findings: ventricular volume measures 38,816 mm³, 5.0% above the reference mean. With a Z-score of 0.14 (55.4th percentile), this represents normal volume ; hippocampal volume measures 5,849 mm³, 9.9% below the reference mean. With a Z-score of -0.80 (21.3th percentile), this represents normal volume ; whole brain volume measures 1,086,570 mm³, 17.1% above the reference mean. With a Z-score of 2.05 (98.0th percentile), this represents significant enlargement; entorhinal cortex volume measures 3,189 mm³, 7.9% below the reference mean. With a Z-score of -0.43 (33.5th percentile), this represents normal volume ; fusiform gyrus volume measures 17,976 mm³, 11.6% above the reference mean. With a Z-score of 0.87 (80.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,902 mm³, 10.4% above the reference mean.

  "gpt_diagnosis": "**Reasoning:** The hippocampal volume is slightly below the reference mean (Z-score -0.80, 21.3rd percentile), but still within the normal range. Cognitive scores (MMSE 26, MoCA 25) are borderline but not definitively impaired. Biomarkers (T-tau, P-tau, AV45) are normal, and there is no APOE4 risk allele.  \n\n**Diagnosis:** **CN (Cognitively Normal)**  \n**Confidence:** **Medium** (due to borderline cognitive scores and slightly reduced hippocampal volume, but no clear biomarker or clinical evidence of impairment)",
