Objective: The aim of this study was to assess the ultrasonographic united stiffness score system (UUSSS) in diagnosing thyroid nodules, and retrospectively analyze the discrepancy between acoustic radiation force impulse (ARFI) and real-time elastography (RTE).
Methods: 170 conventional ultrasound (US) proven thyroid nodules in 70 patients were included and all were examined by RTE and ARFI. RTE and ARFI were first analyzed respectively, comparing with pathological findings. Then nodules have discrepancy between ARFI and RTE were retrospectively analyzed by UUSSS.
Results: The AUC (area under curve) of ARFI combined RTE in 170 nodules was 0.87 (sensitivity=79.4% (54/68), specificity=84.3% (86/102), PPV=77.1% (54/70), NPV=86.0% (86/100), accuracy for ARFI were 82.4% (140/170), relatively to RTE was 0.83, 80.9%, 65... View More»
