With a Z-score of 0.70 (75.7th percentile), this represents normal volume ; hippocampal volume measures 7,500 mm³, 0.8% below the reference mean. With a Z-score of -0.08 (47.0th percentile), this represents normal volume ; whole brain volume measures 1,042,780 mm³, 3.4% below the reference mean. With a Z-score of -0.44 (33.0th percentile), this represents normal volume ; entorhinal cortex volume measures 3,767 mm³, 8.1% below the reference mean. With a Z-score of -0.55 (29.1th percentile), this represents normal volume ; fusiform gyrus volume measures 17,220 mm³, 8.6% below the reference mean. With a Z-score of -0.73 (23.2th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,976 mm³, 3.0% above the reference mean.

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Biomarkers (Aβ, T-tau, P-tau, AV45) are normal, and cognitive scores (MMSE 27, MoCA 24) are within expected ranges for age, though MoCA is borderline.  \n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** Medium (MoCA score is slightly low but not indicative of MCI/dementia given normal biomarkers and volumes)",
