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...

OBJECTIVE Evaluation of a new iterative reconstruction algorithm (IMR) for detection/rule-out of pulmonary embolism (PE) in ultra-low dose computed tomography pulmonary angiography (CTPA). METHODS Lower dose CT data sets were simulated based on CTPA examinations of 16 patients with pulmonary embolism (PE) with dose levels (DL) of 50%, 25%, 12.5%, 6.3% or 3.1% of the original tube current sett...

PURPOSE Evaluation of the potential usability of an iPad 3 with a high-resolution display in CT emergency diagnosis compared to a 3 D PACS workstation. MATERIALS AND METHODS 3 readers used a 5-point Likert scale to evaluate 40 CCT scans and 40 CTPA scans to determine the detectability of early signs of infarction in CCT or segmental and subsegmental pulmonary embolisms in CT angiography of th...

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...

PURPOSE To assess image quality of CT pulmonary angiography (CTPA) at reduced radiation exposure (RD-CTPA) and contrast medium (CM) volume using two different iterative reconstruction (IR) algorithms (iDose4 and iterative model reconstruction (IMR)) in comparison to filtered back projection (FBP). MATERIALS AND METHODS 52 patients (body weight < 100 kg, mean BMI: 23.9) with suspected pulmonar...

AIM Controversy surrounds prevention, detection and clinical relevance of pulmonary embolism (PE) following arthroplasty in orthopaedic patients. We aimed to review the rates of computer tomography pulmonary angiography (CTPA), PE and fatal PE following total joint replacement. METHOD Mixed retrospective/prospective review of CTPA requests and PE incidence amongst patients undergoing primary ...

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...

Aims. To study the use of CT pulmonary angiography (CTPA) at Hutt Hospital and investigate the use of pretest probability scoring in the assessment of patients with suspected pulmonary embolism (PE). Methods. We studied patients with suspected PE that underwent CTPA between January and May 2012 and collected data on demographics, use of pretest probability scoring, and use of D Dimer and compar...

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...

RATIONALE AND OBJECTIVES The purposes of this study were to assess the accuracy of trainee radiologists' reports for computed tomographic pulmonary angiographic (CTPA) imaging and to determine agreement or discrepancy with final verified consultant reports. MATERIALS AND METHODS A total of 100 consecutive out-of-hours CTPA examinations were prospectively analyzed. Fifty-one male and 49 female...
