[New imaging techniques in pulmonary embolism].
Acute pulmonary embolism is a medical emergency and diagnostic certitude must be obtained as early as possible. In clinically serious situations, spiral CT is a reliable diagnostic tool. It provides direct signs of embolism with visualisation of thrombi in the pulmonary arteries as far as the segmental branches and its diagnostic value does not change in cases of pulmonary parenchymal involvement. In emergencies, spiral CT should replace pulmonary angiography, which is more costly and associated with greater morbidity and mortality. Other methods, in particular MRI, which is totally innocuous, could play an important role in the diagnostic strategy of acute pulmonary embolism in the near future.
