title: [Diagnostic imaging in acute pulmonary embolism. The use of spiral computed tomography, lung scintigraphy and echocardiography].
abstract: Acute pulmonary embolism is an underdiagnosed and potentially lethal condition. Treatment may be lifesaving but is associated with severe side effects. Thus, reliable diagnostic imaging is essential. We conducted a literature review on the use of spiral computed tomography, lung scintigraphy and echocardiography in acute pulmonary embolism and identified 562 articles, of which 16 original papers met our inclusion criteria. From these, we concluded that none of the modalities is applicable in every situation. Spiral computed tomography can confirm the diagnosis but cannot rule out subsegmental embolism. With lung scintigraphy, perfusion imaging alone is probably sufficient and suited to both confirming and ruling out the diagnosis. Echocardiography should be reserved for patients with an emergent need for treatment and cannot rule out the diagnosis.
