background: considering the importance of using more appropriate imaging technique for accurate diagnosis of pulmonary thromboembolism (pte) with less side eff ects, we aimed to evaluate the quality of pulmonary 64-multidetector computed tomographic (mdct) angiography in pregnant and postpartum women with suspected pte in isfahan. materials and methods:in this descriptive study, radiological fi...

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...

HYPOTHESIS Spiral computed tomographic pulmonary angiography (CTPA) is sensitive and specific in diagnosing pulmonary embolism (PE) in critically ill surgical patients. DESIGN Prospective study comparing CTPA with the criterion standard, pulmonary angiography (PA). SETTING Surgical intensive care unit of an academic hospital. PATIENTS Twenty-two critically ill surgical patients with clini...

LESS ISMORE Computed Tomographic Pulmonary Angiography: Clinical Implications of a LimitedNegative Result A substantial proportion of computed tomographic pulmonary angiography (CTPA) results are degraded by patientrelated and technical factors, yielding a limited negative interpretation, which qualifies the definitive exclusion of pulmonaryembolism.This leads todiagnosticuncertaintyand may aff...

OBJECTIVES The objective of this study was to determine whether automated quantification of lung perfused blood volume (PBV) in dual-energy computed tomographic pulmonary angiography (DE-CTPA) can be used to assess the severity and regional distribution of pulmonary hypoperfusion in emphysema. MATERIALS AND METHODS We retrospectively analyzed 40 consecutive patients (mean age, 67 [13] years) ...

The clinical diagnosis of acute pulmonary embolism (PE) is frequently considered in patients presenting to the emergency department or when hospitalized. Since symptoms are a-specific and the consequences of anticoagulant treatment are considerable, objective tests to either establish or refute the diagnosis have become a standard of care. Computed tomographic pulmonary angiography (CTPA), whic...

The past decade has seen a shift in the imaging paradigm for acute pulmonary embolism (PE) from a combination of clinical acumen, ventilation-perfusion scintigraphy, and conventional pulmonary angiography to computed tomographic pulmonary angiography (CTPA). The ability to perform CT rapidly with direct visualization of thrombi allows for rapid and reliable diagnosis or exclusion of PE in the v...

The best diagnostic strategy to confirm or exclude pulmonary embolism (PE) suspicion needs an appropriate combination of clinical assessment, plasma D-dimer measurement, and computed tomographic pulmonary angiography (CTPA). CTPA should be used with caution in some patient groups, such as patients with known allergy to contrast media, those with severe renal insufficiency, and pregnant women, a...

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...
