  "img_finding": "Image findings: ventricular volume measures 19,478 mm³, 12.8% below the reference mean. With a Z-score of -0.32 (37.4th percentile), this represents normal volume ; hippocampal volume measures 7,045 mm³, 8.3% below the reference mean. With a Z-score of -0.93 (17.5th percentile), this represents normal volume ; whole brain volume measures 1,051,760 mm³, 2.2% above the reference mean. With a Z-score of 0.27 (60.8th percentile), this represents normal volume ; entorhinal cortex volume measures 4,153 mm³, 6.7% above the reference mean. With a Z-score of 0.52 (69.8th percentile), this represents normal volume ; fusiform gyrus volume measures 20,159 mm³, 10.7% above the reference mean. With a Z-score of 1.21 (88.6th percentile), this represents mild enlargement; middle temporal gyrus volume measures 22,996 mm³, 12.1% above the reference mean. With a Z-score of 1.07 (85.8th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "Reasoning: The brain volume measurements are within normal ranges or show mild enlargement, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. Cognitive scores (MMSE 29, MoCA 26) are within normal limits, and the absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
