  "img_finding": "Image findings: ventricular volume measures 82,102 mm³, 113.2% above the reference mean. With a Z-score of 2.71 (99.7th percentile), this represents significant enlargement; hippocampal volume measures 6,525 mm³, 13.7% below the reference mean. With a Z-score of -1.33 (9.1th percentile), this represents mild atrophy; whole brain volume measures 1,067,180 mm³, 1.1% below the reference mean. With a Z-score of -0.15 (44.2th percentile), this represents normal volume ; entorhinal cortex volume measures 3,971 mm³, 3.2% below the reference mean. With a Z-score of -0.21 (41.5th percentile), this represents normal volume ; fusiform gyrus volume measures 16,926 mm³, 10.2% below the reference mean. With a Z-score of -0.86 (19.4th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,161 mm³, 10.2% below the reference mean. With a Z-score of -0.92 (17.9th percentile), this represents normal volume . ",

  "gpt_diagnosis": "**Reasoning:** The data shows significant ventricular enlargement (Z-score 2.71) and mild hippocampal atrophy (Z-score -1.33), both of which are associated with neurodegenerative processes. The cognitive scores (MMSE 23, MoCA 20) are below normal ranges for age, suggesting cognitive impairment, but not severe enough for a dementia diagnosis.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI)**  \n**Confidence:** **Medium** (Cognitive scores align with MCI, but clinical correlation with functional decline would strengthen confidence.)",
