  "img_finding": "Image findings: ventricular volume measures 11,844 mm³, 60.6% below the reference mean. With a Z-score of -1.44 (7.5th percentile), this represents mild atrophy; hippocampal volume measures 8,534 mm³, 6.3% above the reference mean. With a Z-score of 0.63 (73.6th percentile), this represents normal volume ; whole brain volume measures 1,217,740 mm³, 7.3% above the reference mean. With a Z-score of 1.04 (85.0th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,901 mm³, 8.5% below the reference mean. With a Z-score of -0.59 (27.8th percentile), this represents normal volume ; fusiform gyrus volume measures 21,703 mm³, 9.0% above the reference mean. With a Z-score of 0.75 (77.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,164 mm³, 3.4% above the reference mean. With a Z-score of 0.28 (60.9th percentile), this represents normal volume . ",

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