  "img_finding": "Image findings: ventricular volume measures 22,714 mm³, 24.4% below the reference mean. With a Z-score of -0.58 (28.1th percentile), this represents normal volume ; hippocampal volume measures 8,390 mm³, 4.5% above the reference mean. With a Z-score of 0.45 (67.4th percentile), this represents normal volume ; whole brain volume measures 1,106,680 mm³, 2.5% below the reference mean. With a Z-score of -0.35 (36.4th percentile), this represents normal volume ; entorhinal cortex volume measures 4,113 mm³, 3.5% below the reference mean. With a Z-score of -0.24 (40.4th percentile), this represents normal volume ; fusiform gyrus volume measures 20,809 mm³, 4.5% above the reference mean. With a Z-score of 0.38 (64.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,820 mm³, 1.8% above the reference mean. With a Z-score of 0.15 (56.0th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges, with Z-scores close to the mean. Cognitive scores (MMSE 27, MoCA 25) are also within normal limits, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
