  "img_finding": "Image findings: ventricular volume measures 24,701 mm³, 10.6% above the reference mean. With a Z-score of 0.26 (60.4th percentile), this represents normal volume ; hippocampal volume measures 7,632 mm³, 0.7% below the reference mean. With a Z-score of -0.08 (46.9th percentile), this represents normal volume ; whole brain volume measures 1,133,870 mm³, 10.2% above the reference mean. With a Z-score of 1.27 (89.7th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,600 mm³, 7.5% below the reference mean. With a Z-score of -0.58 (28.0th percentile), this represents normal volume ; fusiform gyrus volume measures 18,891 mm³, 3.7% above the reference mean. With a Z-score of 0.42 (66.3th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,659 mm³, 10.4% above the reference mean. With a Z-score of 0.93 (82.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges or show mild enlargement, with no significant atrophy. Cognitive scores (MMSE and MoCA) are perfect (30/30), and there is no APOE4 genetic risk factor.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
