A 25-year-old man presented with symptoms of syncope, cough, headache and hemoptysis. Cranial MR and venography showed thrombus formation in the right transverse sinus and superior sagittal sinus. Computed tomographic pulmonary angiography (CTPA) showed an embolic thrombus in the right pulmonary truncus and lung abscess. The patient was young, and there were no signs of lower extremity deep ven...

BACKGROUND Majority of our computed tomography-pulmonary angiography (CTPA) scans report negative findings. We hypothesized that suboptimal reliance on diagnostic algorithms contributes to apparent overuse of this test. METHODS A retrospective review was performed on 2031 CTPA cases in a large hospital system. Investigators retrospectively calculated pretest probability (PTP). Use of CTPA was...

The septal angle, an angle between the interventricular septum and the line connecting the sternum midpoint and thoracic vertebral spinous process, as measured by computed tomographic pulmonary angiography (CTPA), has been observed to be increased in patients with pulmonary hypertension (PH), but its meaning remains unclear. The aim of this study was to investigate the potential role of the sep...

The introduction of computed tomography pulmonary angiography (CTPA) has led to an increase in the incidence of pulmonary embolism (PE) diagnosis. However, the case fatality rate is lower and the mortality rates of PE have remained unchanged, suggesting a lower severity of illness. Specifically, the multiple-detector CTPA increased the rate of subsegmental filling defect reported in patients wi...

PURPOSE Pulmonary embolism (PE) has a significant associated morbidity and mortality. The role of diagnostic imaging in PE is being increasingly undertaken by computed tomography pulmonary angiography (CTPA). An advantage of CTPA is its ability to simultaneously provide information on the lung parenchyma, mediastinum, pleural spaces, and chest wall. A sample of CTPAs was therefore reviewed to i...

Objective: To assess the current level of knowledge and practice patterns of emergency physicians regarding radiation exposure from diagnostic imaging modalities for investigating acute pulmonary embolism (PE). Methods: An online survey was sent to adult emergency physicians working at two academic tertiary care adult emergency departments (EDs) to determine imaging choices for investigating PE...

Introduction: Computed Tomography Pulmonary Angiography (CTPA) among pregnant women is often non-diagnostic and may need the repetition of CTPA. This study aims to compare test bolus tracking protocols for CTPA by analysing mean contrast enhancement pulmonary artery, diagnostic quality radiation dosage, as well outcome repeated due initial Methods: retrospective from two tertiary centres includ...

Objective: The incidence of pulmonary embolism (PE) increases with COVID-19. With the pandemic, changes occur in utilization computed tomography angiography (CTPA), which we use diagnosis PE. In our study, investigated impact pandemic on utilized and result CTPA.
 Methods: Patients over age 18 who applied to emergency department between 01.03.2019 28.02.2021 underwent CTPA was included thi...

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...
