  "img_finding": "Image findings: ventricular volume measures 19,601 mm³, 12.2% below the reference mean. With a Z-score of -0.31 (38.0th percentile), this represents normal volume ; hippocampal volume measures 7,219 mm³, 6.1% below the reference mean. With a Z-score of -0.68 (24.8th percentile), this represents normal volume ; whole brain volume measures 1,055,730 mm³, 2.6% above the reference mean. With a Z-score of 0.32 (62.6th percentile), this represents normal volume ; entorhinal cortex volume measures 3,668 mm³, 5.8% below the reference mean. With a Z-score of -0.45 (32.7th percentile), this represents normal volume ; fusiform gyrus volume measures 20,795 mm³, 14.2% above the reference mean. With a Z-score of 1.60 (94.5th percentile), this represents moderate enlargement; middle temporal gyrus volume measures 23,539 mm³, 14.7% above the reference mean. With a Z-score of 1.31 (90.5th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex) are within normal ranges, with Z-scores close to the mean. The MMSE and MoCA scores are both high (28/30), indicating no significant cognitive impairment. The absence of APOE4 further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
