  "img_finding": "Image findings: ventricular volume measures 26,872 mm³, 20.3% above the reference mean. With a Z-score of 0.51 (69.4th percentile), this represents normal volume ; hippocampal volume measures 8,095 mm³, 5.3% above the reference mean. With a Z-score of 0.60 (72.6th percentile), this represents normal volume ; whole brain volume measures 1,030,570 mm³, 0.1% above the reference mean. With a Z-score of 0.02 (50.7th percentile), this represents normal volume ; entorhinal cortex volume measures 3,480 mm³, 10.6% below the reference mean. With a Z-score of -0.82 (20.6th percentile), this represents normal volume ; fusiform gyrus volume measures 16,410 mm³, 9.9% below the reference mean. With a Z-score of -1.11 (13.3th percentile), this represents mild atrophy; middle temporal gyrus volume measures 19,931 mm³, 2.9% below the reference mean. With a Z-score of -0.25 (39.9th percentile), this represents normal volume . ",

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain volume data shows mostly normal measurements, with mild atrophy only in the fusiform gyrus. Cognitive scores (MMSE 30, MoCA 28) are within the normal range, and there is no APOE4 genetic risk factor. The entorhinal cortex is slightly reduced but still within normal limits.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
