title: [Diagnosis of pulmonary embolism: lung perfusion scintigraphy and thoracic roentgenography. Comparison of results in 472 patients with suspected pulmonary embolism].
abstract: Although lung-perfusion scintigraphy has been proved to be the most helpful method in the diagnosis of suspected pulmonary embolism, especially in comparison with actual chest-X-ray or ventilation studies, sometimes problems occur in interpreting the scan. The aim of the present retrospective study in 472 patients with suspected pulmonary embolism was to reevaluate the reliability of direct and indirect radiological findings typical for pulmonary embolism. Out of 155 patients with confirmed pulmonary embolism 41% showed those signs in chest-X-ray (true-positive). 59% cases were found to be false-negative. Patients without pulmonary embolism (84%) did not demonstrate any radiological symptoms typical for pulmonary embolism (true-negative) but 16% did (false-positive). Physicians should pay more attention to X-ray findings despite the fact, that their sensitivity and specificity are low, because radiological symptoms represent important additional information, helpful especially in controversial clinical results.
