Weight-based contrast administration in the computerized tomography evaluation of acute pulmonary embolism
Compare individualized contrast protocol, or weight-based protocol, to standard methodology in evaluating acute pulmonary embolism.Retrospective chart review was performed on patients undergoing computed tomography angiography with standard contrast protocol (n = 50) or individualized protocol (n = 50). Computerized tomography images were assessed for vascular enhancement and image quality.Demo...
متن کاملdiagnostic value of dual-source computerized tomography combined with perfusion imaging for peripheral pulmonary embolism
conclusion ped software of dual-source ct combined with perfusion imaging can significantly improve the detection rate of peripheral pulmonary embolism. results ctpa images revealed 50 (7.81%) segmental and 56 (4.38%) sub-segmental pulmonary embolisms, while the ped images showed 68 (10.63%) segmental and 94 (7.34%) sub-segmental pulmonary embolisms. thus, the detection rate on ped images for p...
متن کاملSpiral computed tomography for the diagnosis of acute pulmonary embolism.
The accuracy of computed tomography (CT) imaging for the diagnosis of acute pulmonary embolism (PE) was reviewed. Single detector CT, based on pooled data, showed a sensitivity of 73% and multidetector CT, mostly 4-slice, showed a sensitivity of 83%. Respective specificities were 87% and 96%. Among patients with suspected PE evaluated with single slice CT, 20% of patients found to have venous t...
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 کاملDiagnosis of pulmonary embolism.
Recent clinical studies have shed new light on the diagnosis of venous thromboembolism. Pulmonary embolism continues to be difficult to diagnose because the definitive test, pulmonary angiography, is complex and not widely available. However, new knowledge about ventilation perfusion lung scanning and non-invasive leg studies can help to reduce the need for pulmonary angiography. Furthermore, t...
