  "img_finding": "Image findings: ventricular volume measures 53,503 mm³, 44.7% above the reference mean. With a Z-score of 1.21 (88.6th percentile), this represents mild enlargement; whole brain volume measures 789,513 mm³, 14.9% below the reference mean. With a Z-score of -1.79 (3.6th percentile), this represents moderate atrophy. ",

Medical history: Psychiatric; Head, Eyes, Ears, Nose and Throat; Cardiovascular; Respiratory; Musculoskeletal; Gastrointestinal; Renal-Genitourinary; Allergies or Drug Sensitivities; Major Surgical Procedures. MMSE: 27.0. MoCA: 24.0. Logical Memory: 0.0. APOEε4 alleles: 0.0. Biomarker levels: Florbetapir (AV45): 0.94 SUVR (mild reduced). ",

  "gpt_diagnosis": "**Reasoning:** The imaging data shows moderate whole brain atrophy and mild ventricular enlargement, which are consistent with neurodegenerative changes. The cognitive scores (MMSE 27, MoCA 24) are borderline for mild cognitive impairment (MCI), but the absence of APOE4 and only mild amyloid deposition (AV45) suggests a slower progression.  \n\n**Diagnosis:** **MCI**  \n**Confidence:** **Medium** (due to borderline cognitive scores and lack of strong genetic/amyloid risk factors)",
