  "img_finding": "Image findings: ventricular volume measures 32,831 mm³, 17.0% above the reference mean. With a Z-score of 0.39 (65.1th percentile), this represents normal volume ; hippocampal volume measures 8,271 mm³, 16.3% above the reference mean. With a Z-score of 1.49 (93.2th percentile), this represents mild enlargement; whole brain volume measures 1,086,720 mm³, 11.5% above the reference mean. With a Z-score of 1.45 (92.6th percentile), this represents mild enlargement; entorhinal cortex volume measures 4,217 mm³, 14.8% above the reference mean. With a Z-score of 0.91 (81.8th percentile), this represents normal volume ; fusiform gyrus volume measures 19,276 mm³, 13.3% above the reference mean. With a Z-score of 1.21 (88.7th percentile), this represents mild enlargement; middle temporal gyrus volume measures 19,994 mm³, 4.3% above the reference mean. With a Z-score of 0.37 (64.6th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The brain volume measures are generally above the reference mean, with mild enlargement in the hippocampus, whole brain, and fusiform gyrus, while other regions are within normal ranges. Cognitive scores (MMSE 29, MoCA 24) are borderline for MCI (MoCA <26 suggests possible MCI), but the absence of APOE4 and preserved brain volumes argue against significant neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (MoCA is slightly low, but structural findings and lack of APOE4 support normal",
