BACKGROUND Computed tomographic pulmonary angiography (CTPA) is a gold standard test for the diagnosis of pulmonary embolism (PE), but is reported to be over prescribed. We performed this study to determine over prescription of CTPAs at a District General Hospital (DGH) in the United Kingdom. Our secondary aim was to establish a cause of its over-prescription. METHODS We retrospectively revie...
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 o...
OBJECTIVE To quantify right ventricular dysfunction (RVD) and pulmonary obstruction index assessed by computed tomographic pulmonary angiography (CTPA) to assess the predictive value of these CT parameters for mortality after the initial diagnosis of acute pulmonary embolism (APE). MATERIAL AND METHOD In 81 consecutive patients with proved APE, two readers assessed the extent of RVD, the shap...

BACKGROUND Invasive mold diseases (IMDs) of the lung remain a challenge for immunocompromised patients. Although timely diagnosis and treatment are crucial for the outcome of the infection, the poor sensitivity of microbiological techniques and the limited specificity of chest high-resolution computed tomography (HRCT) often delay definitive diagnosis of these infections. METHODS To explore t...
introduction: pulmonary embolism (pe) is a common lethal disease that its clinical symptoms may be seen in many other diseases. computed tomography pulmonary angiography (ctpa) is a valuable diagnostic modality for detection of pe. in addition, it can accurately detect the other diseases with clinical symptoms similar to pe. the aim of this study is to evaluate the frequency of pe and nonemboli...
Pulmonary embolism (PE) is a very serious condition causing sudden death in about one-third of the cases. Treatment with anti-clotting medications is highly effective but not without complications, while diagnosis has been missed in about 70% of the cases. A major clinical challenge, particularly in an Emergency Room, is to quickly and correctly diagnose patients with PE and then send them on t...

Pulmonary embolism, a medical emergency for pulmonary physicians, is defined as a blockage of the main artery of the lung or one of its branches by embolism, from many sources, such as thrombus, air, amniotic fluid, tumor, or fat.1 A good clinician, especially a pulmonary or critical care physician, should consider the possible diagnosis of pulmonary embolism in a highly suspected patient, sinc...
