  "img_finding": "Image findings: ventricular volume measures 16,075 mm³, 42.7% below the reference mean. With a Z-score of -0.98 (16.4th percentile), this represents normal volume ; hippocampal volume measures 7,888 mm³, 10.9% above the reference mean. With a Z-score of 1.00 (84.1th percentile), this represents normal volume ; whole brain volume measures 1,011,780 mm³, 3.8% above the reference mean. With a Z-score of 0.48 (68.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,642 mm³, 0.8% below the reference mean. With a Z-score of -0.05 (47.9th percentile), this represents normal volume ; fusiform gyrus volume measures 18,826 mm³, 10.7% above the reference mean. With a Z-score of 0.97 (83.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,619 mm³, 12.8% above the reference mean. With a Z-score of 1.11 (86.6th percentile), this represents mild enlargement. ",

  "gpt_diagnosis": "**Reasoning:** All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) are within normal ranges or show mild enlargement, with no significant atrophy. Cognitive scores (MMSE 28, MoCA 25) are within normal limits for age, and APOE4 status (heterozygous) does not strongly indicate imminent decline.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
