  "img_finding": "Image findings: ventricular volume measures 29,554 mm³, 32.3% above the reference mean. With a Z-score of 0.81 (79.1th percentile), this represents normal volume ; hippocampal volume measures 7,388 mm³, 3.9% below the reference mean. With a Z-score of -0.43 (33.2th percentile), this represents normal volume ; whole brain volume measures 1,099,970 mm³, 6.9% above the reference mean. With a Z-score of 0.86 (80.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,815 mm³, 2.0% below the reference mean. With a Z-score of -0.16 (43.8th percentile), this represents normal volume ; fusiform gyrus volume measures 18,628 mm³, 2.3% above the reference mean. With a Z-score of 0.26 (60.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,689 mm³, 15.4% above the reference mean. With a Z-score of 1.37 (91.5th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "Reasoning: All brain volumes (including hippocampal, entorhinal cortex, and fusiform gyrus) are within normal ranges, with no significant atrophy. Biomarkers (Aβ, T-tau, P-tau) are normal, and cognitive scores (MMSE 27, MoCA 22) suggest mild cognitive impairment (MCI) but not dementia.  \nDiagnosis: MCI  \nConfidence: Medium (MoCA score is borderline, but biomarker and structural data do not support dementia or significant neurodegeneration).",
