  "img_finding": "Image findings: ventricular volume measures 58,513 mm³, 24.5% above the reference mean. With a Z-score of 0.71 (76.1th percentile), this represents normal volume ; whole brain volume measures 1,096,280 mm³, 6.5% above the reference mean. With a Z-score of 0.85 (80.4th percentile), this represents normal volume ; entorhinal cortex volume measures 3,735 mm³, 5.9% below the reference mean. With a Z-score of -0.39 (35.0th percentile), this represents normal volume ; fusiform gyrus volume measures 15,404 mm³, 14.7% below the reference mean. With a Z-score of -1.28 (10.1th percentile), this represents mild atrophy; middle temporal gyrus volume measures 20,265 mm³, 0.5% above the reference mean. With a Z-score of 0.04 (51.7th percentile), this represents normal volume . ",

Medical history: Neurologic; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Musculoskeletal; Renal-Genitourinary; Malignancy; Major Surgical Procedures. MMSE: 30.0. MoCA: 27.0. Logical Memory: 9.0. APOEε4 alleles: 0.0. ",

  "gpt_diagnosis": "**Reasoning:** The brain volume data shows mild atrophy in the fusiform gyrus but otherwise normal volumes in other regions, including the entorhinal cortex and middle temporal gyrus. Cognitive scores (MMSE 30, MoCA 27) are within normal limits for age, and there is no APOE4 genetic risk factor.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (due to mild fusiform atrophy but preserved cognition and no other significant atrophy)",
