“…In 1980 Godwin et al reported for the first time the direct demonstration of endovascular clots in central PEs [24]. Technical parameters were a dynamic sequential contrast-enhanced scanning, 5-or 10-mm collimation, and a rotation time of 2.4-4.8 s. In 1984 Breatnach and Stanley reported the first demonstration of a segmental embolus with CT [25].…”

Over the past 10 years, spiral CT angiography of the pulmonary arteries has reached a high accuracy in the evaluation of pulmonary embolism. Major advantages of CT compared with ventilation/perfusion lung scintigraphy and pulmonary angiography is direct visualization of clots in the pulmonary arteries, and to provide alternative findings or diagnosis. The recent introduction of multislice CT has improved the evaluation of peripheral pulmonary arteries, enabling high-resolution CT examinations over the entire thorax in a short breathhold. The examination techniques, imaging findings, pitfalls, and results of CT in the diagnosis of pulmonary embolism are reviewed in comparison with other diagnostic tests.

“…This requires optimal enhancement of vessels to avoid pseudofilling defects in pulmonary arteries secondary to flow phenomena. With the use of dynamic scanning, emboli in central or lobar vessels could be detected [42][43][44]. However, conventional CT requires relatively long scan times, which allows respiratory motion artefacts that severely limit its usefulness as a diagnostic test for PE.…”

Pulmonary embolism often remains a difficult diagnosis for the clinician, particularly in patients with comorbidity factors. This is in contrast with the availability of effective treatment, which should be prescribed as soon as possible.To date, there is still no ideal diagnostic test that is accurate, safe, readily available and cost-effective.Recent technical advances in computed tomography, magnetic resonance imaging and laboratory findings have raised new possibilities in the diagnosis of pulmonary embolism.This review covers the performance of different diagnostic tests, and focuses on the advantages and limitations of single diagnostic tests and the clinical usefulness of these tests in diagnostic strategies.

“…Seit den ersten Beschreibungen [3,8,33] hat die computertomographische Diagnostik der Lungenembolie in den vergangenen Jahren zunehmend an Bedeutung gewonnen, hauptsächlich aufgrund der Entwicklung schneller volumetrischer Scan-Verfahren, wie der Spiral-CT (SCT) [14] oder der Elektronenstrahl-CT (EBT) [7,24,25]. Die kontrastverstärkte CT-Angiographie wird mittlerweile vielerorts als das Mittel der ersten Wahl in der Diagnostik der akuten und chronischen Lungenembolie angesehen.…”
