With a Z-score of 0.25 (59.7th percentile), this represents normal volume ; hippocampal volume measures 5,681 mm³, 24.8% below the reference mean. With a Z-score of -2.42 (0.8th percentile), this represents significant atrophy; whole brain volume measures 1,113,200 mm³, 3.1% above the reference mean. With a Z-score of 0.41 (65.8th percentile), this represents normal volume ; entorhinal cortex volume measures 2,972 mm³, 27.5% below the reference mean. With a Z-score of -1.87 (3.1th percentile), this represents moderate atrophy; fusiform gyrus volume measures 15,261 mm³, 19.0% below the reference mean. With a Z-score of -1.62 (5.3th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 22,012 mm³, 3.2% above the reference mean.

  "text_data": "Age is 78.1 years. Gender is Male. Education: 16 years. MMSE: 28.0. Logical Memory: 0.0.

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The patient shows significant hippocampal atrophy (-2.42 Z-score) and moderate atrophy in the entorhinal cortex and fusiform gyrus, which are key regions affected in Alzheimer’s disease. Despite normal MMSE (28/30), the structural changes and moderate Aβ reduction suggest early neurodegeneration.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)** (likely due to Alzheimer’s pathology)  \n**Confidence:** **Medium** (due to normal MMSE but clear structural and biomarker abnormalities)",
