Jul 18, 2024 · The computed tomography pulmonary angiogram (CTPA/CTPE) is a commonly performed diagnostic examination to exclude pulmonary emboli (PE). Each radiology department will have a slightly different method for achieving the same outcome, i.e. diagnostic density of the main pulmonary artery and its branches.

Feb 14, 2025 · 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 …

Dec 1, 2017 · CTPA is the current gold standard in the diagnosis of acute PE with high accuracy, wide availability, and rapid turnaround time. Combining CTPA with clinical pre-test probability of PE yields superior sensitivity and specificity than imagining alone.

A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). [1]

Computed tomography pulmonary angiography (CTPA) is excellent for including and excluding PE, therefore CT is the first-choice diagnostic imaging technique in patients suspected of having acute PE. Due to its wide availability and low invasiveness, CTPA tends to be overused.

Nov 23, 2012 · The potential of the noninvasive technique, CT pulmonary angiography (CTPA), has now been realized at most institutions; it has become the test of choice and thus the de facto standard of care .

Computed tomography pulmonary angiography (CTPA) is the reference investigation of choice to diagnose pulmonary embolism (PE). Nevertheless, the use of CTPA should be weighed against its risks, such as radiation and contrast-induced nephropathy. We aim to assess the yield of CTPA in diagnosing PE at a tertiary centre in Malaysia.

Aug 9, 2016 · A CTPA may show that part of the lung has collapsed; atelectasis, or that there is a fluid collection in the lung lining,; a pleural effusion. Both these conditions can be associated with a PE, but they can also occur with chest infections.

May 30, 2013 · Computed tomography pulmonary angiography (CTPA) has become the first-line imaging method for assessment of patients with clinically suspected acute PE. CTPA is readily available in most hospitals and has been shown to have high sensitivity and specificity for PE, comparable with the traditional gold standard of invasive pulmonary angiography.

CT pulmonary angiogram (CTPA) The CTPA is the gold standard test for suspected acute pulmonary emboli; the risk to fetus is small, outweighed by the danger of missed pulmonary emboli and can be minimized by lead shielding.
