(2013) Case reports in medicine. Do emergency physicians use serum D-dimer effectively to determine the need for CT when evaluating patients for pulmonary embolism? Chest radiography is neither sensitive nor specific for a pulmonary embolism. 29. The physical exam may reveal suggestive features such as: Clinical decision rules, in conjunction with physician gestalt and estimated pretest probability of disease, may serve as a supplement in risk stratification: D-dimer (ELISA) is commonly used as a screening test in patients with a low and moderate probability clinical assessment, on these patients: In patients with a high probability clinical assessment, a D-dimer test is not helpful because a negative D-dimer result does not exclude pulmonary embolism in more than 15%. Can CT pulmonary angiography allow assessment of severity and prognosis in patients presenting with pulmonary embolism? Worsley DF, Alavi A, Aronchick JM et-al. Jiménez D, Aujesky D, Moores L, et al.
