  "img_finding": "Image findings: ventricular volume measures 25,468 mm³, 9.3% below the reference mean. With a Z-score of -0.21 (41.6th percentile), this represents normal volume ; hippocampal volume measures 5,893 mm³, 17.2% below the reference mean. With a Z-score of -1.58 (5.8th percentile), this represents moderate atrophy; whole brain volume measures 982,212 mm³, 0.8% above the reference mean. With a Z-score of 0.10 (53.9th percentile), this represents normal volume ; entorhinal cortex volume measures 2,667 mm³, 27.4% below the reference mean. With a Z-score of -1.68 (4.6th percentile), this represents moderate atrophy; fusiform gyrus volume measures 15,955 mm³, 6.2% below the reference mean. With a Z-score of -0.57 (28.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,320 mm³, 0.8% above the reference mean. With a Z-score of 0.07 (52.7th percentile), this represents normal volume . ",

  "gpt_diagnosis": "Reasoning: The patient exhibits significant hippocampal and entorhinal cortex atrophy (Z-scores of -1.58 and -1.68, respectively), which are hallmark biomarkers of Alzheimer's disease. Combined with profoundly elevated AV45 (amyloid PET) and low cognitive scores (MMSE 17, MoCA 10), this strongly suggests neurodegenerative pathology consistent with Alzheimer's dementia.  \nDiagnosis: **Dementia** (likely Alzheimer's disease)  \nConfidence: **High**",
