INTRODUCTION Computed tomography pulmonary angiography (CTPA) has not only become the method of choice for diagnosing acute pulmonary embolism (PE), it also allows for risk stratification of patients with PE. To date, no study has specifically examined the predictive value of CTPA findings to assess short-term prognosis in elderly patients with acute PE who are particularly vulnerable to advers...

Abstract Background Pulmonary embolism (PE) is one of the known sequels COVID-19 infection. We aimed to assess incidence PE in patients with infection and evaluate relationship between CT severity disease laboratory indicators. This was a retrospective study conducted on 96 proved by positive PCR who underwent pulmonary angiography (CTPA) calculation Available patients’ complaint data at time C...

INTRODUCTION Pulmonary embolism (PE) is a serious cardiovascular and pulmonary complication worldwide. We aimed to assess the implications of different computed tomography pulmonary angiography (CTPA) parameters in patients with acute PE. METHODS A retrospective observational study to include patients presented with clinical suspicious of PE who underwent CTPA was conducted. Patients' demogra...

BACKGROUND Relatively little is known about prognosis in patients for whom suspected pulmonary embolism (PE) is refuted by imaging. AIM This prospective study of suspected PE therefore compared clinico-radiological features and outcome in patients with and without PE. DESIGN AND METHODS Computed tomographic pulmonary angiography (CTPA) confirmed or refuted PE in consecutive patients. Clinic...

This prospective study was designed to assess CT performance by using the task-based image quality assessment and identify influence of iterative reconstruction (IR) algorithm, tube potential pitch factor selection on dose during Computed Tomography Pulmonary Angiography (CTPA) examination. An phantom, Catphan-600 utilized in this for assessing CTPA protocols under 128-multislice scanner (Phili...

There is an increased risk of pulmonary embolism (PE) in patients with malignancy. This increased risk is fourfold above the general population and is further increased if the patient is receiving chemotherapy [1–6]. Between 4 and 28% of cancer patients will develop thromboembolic disease depending on their tumour type and stage [1]. A significant proportion of patients with PE will present wit...

Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. Gathering sensed information in an energy efficient manner is critical to operate the sensor network for a long period of time. Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful infor...

Background: A clinically important impact of Coronavirus Disease 2019 (COVID-19) is the increased likelihood thromboembolism, mainly pulmonary embolism (PE). To screen for these complications a biochemical marker, D-dimer, usually done. There plethora research validating use D-dimer cutoff levels in non-COVID-19 patients, however less so COVID-19 population. Aim: determine number suspected COVI...

Abstract Purpose Percutaneous vertebroplasty (PVP) is a routine operation for the treatment of osteoporotic lumbar compression fractures (OLCFs). As well known, unilateral puncture common method. However, with conventional transpedicular approach (CTPA), cement may be asymmetrically dispersed, so some surgeons use transverse process root-pedicle (TPRPA). The objective this study was to compare ...

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...
