  "img_finding": "Image findings: ventricular volume measures 144,738 mm³, 382.0% above the reference mean. With a Z-score of 9.08 (100.0th percentile), this represents profound enlargement; hippocampal volume measures 6,595 mm³, 17.8% below the reference mean. With a Z-score of -1.78 (3.7th percentile), this represents moderate atrophy; whole brain volume measures 1,016,840 mm³, 10.4% below the reference mean. With a Z-score of -1.47 (7.1th percentile), this represents mild atrophy; entorhinal cortex volume measures 3,609 mm³, 15.3% below the reference mean. With a Z-score of -1.06 (14.4th percentile), this represents mild atrophy; fusiform gyrus volume measures 17,173 mm³, 13.7% below the reference mean. With a Z-score of -1.14 (12.7th percentile), this represents mild atrophy; middle temporal gyrus volume measures 16,819 mm³, 25.0% below the reference mean. With a Z-score of -2.06 (2.0th percentile), this represents significant atrophy. ",

  "gpt_diagnosis": "Reasoning: The data shows profound ventricular enlargement (Z-score 9.08) and significant atrophy in the hippocampus (Z-score -1.78) and middle temporal gyrus (Z-score -2.06), which are hallmark features of Alzheimer's disease. The MMSE score of 24 is below the normal range (typically 26-30), indicating cognitive impairment.  \n\nDiagnosis: Dementia (likely Alzheimer's disease)  \nConfidence: High",
