  "img_finding": "Image findings: ventricular volume measures 28,587 mm³, 25.8% below the reference mean. With a Z-score of -0.62 (26.8th percentile), this represents normal volume ; hippocampal volume measures 7,769 mm³, 2.8% above the reference mean. With a Z-score of 0.27 (60.7th percentile), this represents normal volume ; whole brain volume measures 1,188,380 mm³, 10.1% above the reference mean. With a Z-score of 1.31 (90.5th percentile), this represents mild enlargement; entorhinal cortex volume measures 3,787 mm³, 7.6% below the reference mean. With a Z-score of -0.52 (30.2th percentile), this represents normal volume ; fusiform gyrus volume measures 20,181 mm³, 7.1% above the reference mean. With a Z-score of 0.61 (72.8th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,153 mm³, 0.9% below the reference mean. With a Z-score of -0.08 (46.9th percentile), this represents normal volume . ",

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The brain volume measurements are largely within normal ranges, with no significant atrophy in key regions like the hippocampus or entorhinal cortex. The MoCA score of 23 suggests mild cognitive impairment, but the MMSE of 30 is normal, and there is no APOE4 risk allele.  \n**Diagnosis:** MCI (Mild Cognitive Impairment)  \n**Confidence:** Medium (due to conflicting cognitive scores and normal imaging)",
