BACKGROUND It is unknown whether the observed increase in computed tomography pulmonary angiography (CTPA) utilization has resulted in increased detection of pulmonary emboli (PEs) with a less severe disease spectrum. METHODS Trends in utilization, diagnostic yield, and disease severity were evaluated for 4,048 consecutive initial CTPAs performed in adult patients in the emergency department ...

We compared the effectiveness of 3-dimensional computed tomography pulmonary angiography (3D-CTPA) and thin-section multiplanar reconstruction (MPR) images obtained using contrast-enhanced multidetector row CT (MDCT), in the evaluation of pulmonary artery (PA) branches of the right upper lobe. We studied 127 patients suspected of having lung cancer of the right upper lobe who underwent contrast...

BACKGROUND Computed tomography pulmonary angiography (CTPA) may improve the diagnostic capabilities of CT imaging for invasive mold disease, but its performance relative to other signs (ie, halo sign, hypodense sign, pleural effusion, reversed halo sign) is unknown. METHODS We prospectively compared the diagnostic performance of CTPA vs other CT imaging findings in 100 patients with hematolog...

Computer-aided detection of pulmonary embolism is an important technology method for diagnosing embolism, which can help doctors diagnose quickly and save a lot manpower. However, due to the small area in Computed Tomography Pulmonary Angiography (CTPA) slice images, some previous methods detecting have high number false missed detection. This study proposes based on improved faster region-base...

Pulmonary embolism (PE) is a frequent and potentially lethal disease caused by the migration of a thrombus to the pulmonary circulation, typically from the venous system of the lower limbs. Unfortunately, there are no specific sets of symptoms which accurately predict or exclude the diagnosis. Therefore, in clinical practice, the diagnosis always strongly relies on imaging. On the other hand, c...

Swine flue is a highly contagious acute respiratory disease caused by a subtype of influenza A virus. Herein we present three patients with H1N1 infection complicated with pulmonary thromboembolism. The patients had chest pain and unexplained dyspnea. Imaging studies showed bilateral hilar predominance. Computed tomographic angiography confirmed bilateral thromboembolism (an unusual presentatio...

background: the aim of the study is to determine the correlation between clinical and echocardiographic fi ndings and risk factors of patients with suspected acute pulmonary thromboembolism (pte) who underwent computed tomography pulmonary angiography (ctpa). materials and methods: in this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of pte referr...

UNLABELLED Pulmonary hypertension (PH) is a progressive disease with a poor prognosis. Identifying chronic thromboembolic pulmonary disease as a cause of PH has major clinical implications as these patients could be potentially offered a surgical cure. Ventilation-perfusion (V/Q) scintigraphy has a high sensitivity to detect embolic disease but its value has been challenged with the emergence o...

SARS-CoV-2 is a virus of the coronavidae family that causes COVID-19, disease emerged in 2019 and has already gone around world, causing World Health Organization to decree pandemic state 2020. One consequences COVID-19 development Pulmonary Thromboembolism (PE), which one or more pulmonary arteries are blocked by blood clot. In this association with PE caused pro-inflammatory hypercoagulant de...
