  "img_finding": "Image findings: ventricular volume measures 26,604 mm³, 5.2% below the reference mean. With a Z-score of -0.12 (45.2th percentile), this represents normal volume ; hippocampal volume measures 6,588 mm³, 7.4% below the reference mean. With a Z-score of -0.68 (24.9th percentile), this represents normal volume ; whole brain volume measures 981,982 mm³, 0.8% above the reference mean. With a Z-score of 0.09 (53.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,479 mm³, 5.3% below the reference mean. With a Z-score of -0.32 (37.3th percentile), this represents normal volume ; fusiform gyrus volume measures 16,076 mm³, 5.5% below the reference mean. With a Z-score of -0.50 (30.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,768 mm³, 2.1% below the reference mean. With a Z-score of -0.18 (42.8th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive assessments (MMSE: 30, MoCA: 29) are also within normal limits, and there is no APOE4 genetic risk factor.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
