  "img_finding": "Image findings: ventricular volume measures 40,377 mm³, 14.1% below the reference mean. With a Z-score of -0.41 (34.1th percentile), this represents normal volume ; hippocampal volume measures 6,978 mm³, 0.1% above the reference mean. With a Z-score of 0.01 (50.5th percentile), this represents normal volume ; whole brain volume measures 975,690 mm³, 5.2% below the reference mean. With a Z-score of -0.68 (24.8th percentile), this represents normal volume ; entorhinal cortex volume measures 4,355 mm³, 9.7% above the reference mean. With a Z-score of 0.64 (73.8th percentile), this represents normal volume ; fusiform gyrus volume measures 17,450 mm³, 3.4% below the reference mean. With a Z-score of -0.30 (38.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,551 mm³, 13.0% below the reference mean. With a Z-score of -1.16 (12.2th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "Reasoning: All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus) are within normal ranges except for mild atrophy in the middle temporal gyrus. Cognitive scores (MMSE 30, MoCA 26) are normal for age, and amyloid PET (AV45) is negative. No significant structural or biomarker evidence of neurodegeneration.  \nDiagnosis: CN (Cognitively Normal)  \nConf",
