  "img_finding": "Image findings: ventricular volume measures 9,058 mm³, 59.4% below the reference mean. With a Z-score of -1.49 (6.8th percentile), this represents mild atrophy; hippocampal volume measures 6,615 mm³, 13.9% below the reference mean. With a Z-score of -1.56 (5.9th percentile), this represents moderate atrophy; whole brain volume measures 999,037 mm³, 2.9% below the reference mean. With a Z-score of -0.36 (35.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,579 mm³, 8.1% below the reference mean. With a Z-score of -0.62 (26.6th percentile), this represents normal volume ; fusiform gyrus volume measures 18,751 mm³, 3.0% above the reference mean. With a Z-score of 0.33 (63.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 18,535 mm³, 9.7% below the reference mean. With a Z-score of -0.86 (19.5th percentile), this represents normal volume . ",

  "true_diagnosis": "Diagnosis: CN.",
  "gpt_diagnosis": "Reasoning: The imaging data shows mild to moderate atrophy in the hippocampus and ventricles, but other brain regions are within normal ranges. Cognitive scores (MMSE, MoCA) are intact, and biomarkers (T-tau, P-tau, AV45) are normal. The absence of APOE4 and preserved cognition suggest no significant impairment.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: Medium (due to hippocampal atrophy but normal biomarkers and cognition)",
