Computed tomographic pulmonary angiography vs ventilation-perfusion lung scanning in patients with suspected pulmonary embolism: a randomized controlled trial.
CONTEXT Ventilation-perfusion (V(dot)Q(dot) lung scanning and computed tomographic pulmonary angiography (CTPA) are widely used imaging procedures for the evaluation of patients with suspected pulmonary embolism. Ventilation-perfusion scanning has been largely replaced by CTPA in many centers despite limited comparative formal evaluations and concerns about CTPA's low sensitivity (ie, chance of...
متن کاملComputerized tomographic pulmonary angiography versus ventilation perfusion lung scanning for the diagnosis of pulmonary embolism.
PURPOSE OF REVIEW The purpose of this review is to focus on recent research that has addressed the relative merits of computed tomographic pulmonary angiography (CTPA) and ventilation perfusion (V/Q) scanning for the diagnosis of pulmonary embolism. RECENT FINDINGS Computed tomographic pulmonary angiography is the most sensitive test for the diagnosis of pulmonary embolism and its use has bee...
متن کاملOveruse and underuse of pulmonary CT angiography in patients with suspected pulmonary embolism
Background: The aim of the present study was to evaluate the utilization and diagnostic yields of CT pulmonary angiography (CTPA) using the Revised Geneva score and Wells’ criteria, in patients with suspected pulmonary embolism (PE). Methods: One hundred and twelve adult patients underwent CTPA for suspected PE were participated in this study. The outcome was positive or neg...
متن کاملMeta-analysis: outcomes in patients with suspected pulmonary embolism managed with computed tomographic pulmonary angiography.
BACKGROUND Spiral computed tomographic pulmonary angiography (CTPA) is increasingly being used in the evaluation of patients with clinically suspected pulmonary embolism (PE). However, CTPA as a definitive diagnostic test may be limited by inadequate sensitivity, especially in instances of isolated subsegmental emboli. PURPOSE To assess the safety of withholding anticoagulation in patients wi...
متن کاملComparison of intravenous digital subtraction angiography with radionuclide ventilation-perfusion lung scanning in patients with suspected pulmonary embolism.
Fifty one patients with suspected pulmonary embolus were studied by radionuclide ventilation-perfusion scanning and intravenous digital subtraction pulmonary angiography. In 31 patients the results of both investigations were reported as negative and in a further 11 both results were reported as positive, giving a concordance rate of 82.3%. In nine patients there was disagreement between the tw...
