  "img_finding": "Image findings: ventricular volume measures 113,234 mm³, 194.0% above the reference mean. With a Z-score of 4.65 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 7,062 mm³, 6.6% below the reference mean. With a Z-score of -0.64 (26.1th percentile), this represents normal volume ; whole brain volume measures 1,051,840 mm³, 2.6% below the reference mean. With a Z-score of -0.33 (37.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,567 mm³, 13.0% below the reference mean. With a Z-score of -0.88 (18.9th percentile), this represents normal volume ; fusiform gyrus volume measures 15,154 mm³, 19.6% below the reference mean. With a Z-score of -1.67 (4.8th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 16,710 mm³, 21.7% below the reference mean. With a Z-score of -1.95 (2.6th percentile), this represents moderate atrophy. ",

  "gpt_diagnosis": "**Reasoning:** The data shows profound ventricular enlargement (194% above mean, Z-score 4.65) and moderate atrophy in the fusiform gyrus (Z-score -1.67) and middle temporal gyrus (Z-score -1.95), alongside significant cognitive impairment (MMSE 16, MoCA 9). These findings strongly suggest neurodegeneration consistent with dementia.  \n\n**Diagnosis:** Dementia  \n**Confidence:** High",
