  "img_finding": "Image findings: ventricular volume measures 30,650 mm³, 9.2% above the reference mean. With a Z-score of 0.21 (58.3th percentile), this represents normal volume ; hippocampal volume measures 6,273 mm³, 11.8% below the reference mean. With a Z-score of -1.08 (13.9th percentile), this represents mild atrophy; whole brain volume measures 917,047 mm³, 5.9% below the reference mean. With a Z-score of -0.74 (22.8th percentile), this represents normal volume ; entorhinal cortex volume measures 3,637 mm³, 1.0% below the reference mean. With a Z-score of -0.06 (47.6th percentile), this represents normal volume ; fusiform gyrus volume measures 13,848 mm³, 18.6% below the reference mean. With a Z-score of -1.69 (4.5th percentile), this represents moderate atrophy; middle temporal gyrus volume measures 16,277 mm³, 15.1% below the reference mean. With a Z-score of -1.31 (9.5th percentile), this represents mild atrophy. ",
  "text_data": "Age is 75.5 years. Gender is Female. Education: 18 years. MMSE: 28.0.

  "true_diagnosis": "Diagnosis: MCI.",
  "gpt_diagnosis": "**Reasoning:** The hippocampal volume shows mild atrophy (Z-score -1.08, 13.9th percentile), and the fusiform gyrus and middle temporal gyrus exhibit moderate and mild atrophy, respectively. However, the MMSE score of 28 is within the normal range, and there is no significant whole-brain or ventricular volume loss. The absence of APOE4 alleles also reduces Alzheimer's risk.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (due to conflicting imaging findings—some atrophy but preserved cognition and no APOE4 risk factor)",
