  "img_finding": "Image findings: ventricular volume measures 7,374 mm³, 75.4% below the reference mean. With a Z-score of -1.79 (3.7th percentile), this represents moderate atrophy; hippocampal volume measures 7,573 mm³, 5.7% below the reference mean. With a Z-score of -0.57 (28.6th percentile), this represents normal volume ; whole brain volume measures 1,064,520 mm³, 6.2% below the reference mean. With a Z-score of -0.87 (19.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,580 mm³, 16.0% below the reference mean. With a Z-score of -1.11 (13.4th percentile), this represents mild atrophy; fusiform gyrus volume measures 19,044 mm³, 4.3% below the reference mean. With a Z-score of -0.36 (35.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,795 mm³, 6.2% above the reference mean. With a Z-score of 0.51 (69.4th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The ventricular volume shows moderate atrophy, while the entorhinal cortex exhibits mild atrophy. Other regions, including the hippocampus, are within normal ranges. The MMSE score of 27 is within the normal range, and the absence of APOE4 reduces genetic risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium",
