  "img_finding": "Image findings: ventricular volume measures 64,067 mm³, 128.3% above the reference mean. With a Z-score of 2.94 (99.8th percentile), this represents significant enlargement; hippocampal volume measures 5,660 mm³, 20.4% below the reference mean. With a Z-score of -1.88 (3.0th percentile), this represents moderate atrophy; whole brain volume measures 978,256 mm³, 0.4% above the reference mean. With a Z-score of 0.05 (51.9th percentile), this represents normal volume ; entorhinal cortex volume measures 2,951 mm³, 19.7% below the reference mean. With a Z-score of -1.21 (11.4th percentile), this represents mild atrophy; fusiform gyrus volume measures 14,398 mm³, 15.4% below the reference mean. With a Z-score of -1.40 (8.1th percentile), this represents mild atrophy; middle temporal gyrus volume measures 15,916 mm³, 17.0% below the reference mean. With a Z-score of -1.47 (7.0th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows significant ventricular enlargement (Z-score 2.94) and moderate hippocampal atrophy (Z-score -1.88), along with mild atrophy in the entorhinal cortex, fusiform gyrus, and middle temporal gyrus. However, Aβ, T-tau, and P-tau levels are normal, and the MMSE score of 25 is only mildly impaired.  \nDiagnosis: Mild Cognitive Impairment (MCI)  \nConfidence: Medium",
