[Diagnostic imaging of acute pulmonary embolism: critical analysis of the 1997 literature].
With variable symptoms and a nonspecific radiographic appearance, acute pulmonary embolism (APE) is a frequent and often undiagnosed cause of mortality and morbidity; thus, availability of an accurate, noninvasive screening examination is highly desirable. Until recently, various noninvasive imaging procedures have been used to detect APE, including ventilation-perfusion scanning, MR imaging and phlebography (or sonography). The low specificity of scintigraphy explains why pulmonary angiography remains the usual "gold standard" modality for detection of APE. However, with this procedure morbidity and mortality not zero-Helical computed tomography (HCT) seems to be an accurate technique for diagnosis of pulmonary embolism except for distal thrombi. Nevertheless the exact position of HCT in the classic algorithms remains to be defined, particularly in terms or cost-benefit results.
