【ACR 2016】急性胸痛－疑似肺栓塞

Clinical decision trees, most notably the Wells criteria, have been developed and validated. There have also been major technological advances, primarily in computed tomography

(CT) and magnetic resonance imaging (MRI). Many clinical studies have evaluated these modalities and the use of imaging in conjunction with clinical criteria and serum assay for D-dimer. It is also of limited value in patients determined to be at high risk of PE by validated clinical criteria. In all other settings, a negative D-dimer test effectively excludes PE or DVT .
