  "img_finding": "Image findings: ventricular volume measures 25,061 mm³, 34.9% below the reference mean. With a Z-score of -0.84 (20.1th percentile), this represents normal volume ; hippocampal volume measures 8,576 mm³, 13.5% above the reference mean. With a Z-score of 1.31 (90.5th percentile), this represents mild enlargement; whole brain volume measures 1,062,460 mm³, 1.6% below the reference mean. With a Z-score of -0.20 (41.9th percentile), this represents normal volume ; entorhinal cortex volume measures 3,814 mm³, 7.0% below the reference mean. With a Z-score of -0.47 (31.8th percentile), this represents normal volume ; fusiform gyrus volume measures 20,659 mm³, 9.7% above the reference mean. With a Z-score of 0.82 (79.5th percentile), this represents normal volume ; middle temporal gyrus volume measures 23,039 mm³, 8.0% above the reference mean. With a Z-score of 0.72 (76.3th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are largely within normal ranges, with hippocampal volume mildly enlarged (unusual but not necessarily pathological). Cognitive scores (MMSE 29, MoCA 25) are borderline for MCI (MoCA <26 suggests possible impairment), but structural imaging does not show atrophy typical of neurodegeneration. APOE4 carrier status increases risk but is not diagnostic.  \n\n**Diagnosis:** **MCI (Mild Cognitive Impairment)**  \n**Confidence:** **Medium** (Cognitive scores suggest possible impairment, but imaging does not strongly support neurodegeneration; clinical correlation needed.)",
