2025年2月14日 · CT pulmonary angiography (CTPA) will show filling defects within the pulmonary vasculature with acute pulmonary emboli. When the artery is viewed in its axial plane the central filling defect from the thrombus is surrounded by a thin …

Imaging plays an important role in the evaluation and management of acute pulmonary embolism (PE). Computed tomography (CT) pulmonary angiography (CTPA) is the current standard of care and provides accurate diagnosis with rapid turnaround time. CT also provides information on other potential causes of acute chest pain.

CT pulmonary angiography (CTPA) is the first-choice diagnostic imaging technique in the diagnostic algorithm for pulmonary embolism. The high accuracy and easy accessibility increased the CTPA orders; however, the indication for CTPA should outweigh its potential risk of X-ray induced malignancy.

2021年7月27日 · If a doctor suspects you may have a pulmonary embolism (PE), a CT scan is the gold standard of imaging techniques. This painless scan uses intravenous (IV) contrast, a type of dye, to help...

2020年12月16日 · Imaging has played an important role in the diagnosis of PE. For many years, ventilation-perfusion (V/Q) scintigraphy has been the main imaging modality for the evaluation of patients with...

CT is an imaging modality that allows for the differential diagnosis of PA sarcoma and PE. It can help differentiate PA sarcoma from PE by visualizing extraluminal tumor extension, expansion of the involved arteries, or a low-attenuation filling defect of the proximal or main PA.

2011年1月1日 · CT pulmonary angiography (CTPA) has become the de facto clinical “gold standard” for the diagnosis of acute pulmonary embolism (PE) and has replaced catheter pulmonary angiography and ventilation-perfusion scintigraphy as the first-line imaging method.

2024年9月14日 · CTPA is the diagnostic imaging test of choice for the evaluation of patients with suspected acute PE as it is widely available, fast, minimally invasive, and cost-effective.

2017年3月17日 · Multidetector-row computed tomographic angiography (CTA) has become the first-line modality for imaging the pulmonary vasculature in patients with suspected acute pulmonary embolism (PE) (Remy-Jardin et al. 2007). This disease is the third most common acute cardiovascular disease after myocardial infarction and stroke in the Unites States and ...

2012年11月23日 · For the more than 25 years that the direct signs of pulmonary embolism have been available to the radiologist on CT, this noninvasive technique has produced a paradigm shift that has raised the standard of care for patients with this disease.
