  "img_finding": "Image findings: ventricular volume measures 23,288 mm³, 4.3% above the reference mean. With a Z-score of 0.11 (54.2th percentile), this represents normal volume ; hippocampal volume measures 7,248 mm³, 5.7% below the reference mean. With a Z-score of -0.64 (26.2th percentile), this represents normal volume ; whole brain volume measures 963,707 mm³, 6.4% below the reference mean. With a Z-score of -0.79 (21.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,503 mm³, 10.0% below the reference mean. With a Z-score of -0.78 (21.9th percentile), this represents normal volume ; fusiform gyrus volume measures 17,416 mm³, 4.4% below the reference mean. With a Z-score of -0.49 (31.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,921 mm³, 16.6% above the reference mean. With a Z-score of 1.47 (93.0th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus) fall within normal ranges based on Z-scores and percentiles, except for a mild enlargement in the middle temporal gyrus, which is not typically associated with neurodegeneration. Cognitive scores (MMSE 29, MoCA 30) are intact, and there is no APOE4 risk allele.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
