PURPOSE The purpose of this investigation was to evaluate the clinical characteristics of acute pulmonary embolism (PE) among patients with PE who did not receive treatment to assess how the natural course of untreated PE relates to its severity. METHODS Data are from the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED). Among patients(More)
The purpose of the present investigation was to test the hypothesis that stratification according to age, in addition to stratification according to the presence or absence of prior CPD, in elderly patients may show criteria on V/Q lung scans that have a higher sensitivity for acute PE than the entire population, while maintaining a high specificity and(More)
UNLABELLED The purpose of this investigation was to identify characteristics or combinations of characteristics of the ventilation-perfusion (V/Q) scan in patients with suspected acute pulmonary embolism (PE) can be used for a "very low probability" interpretation ( < 10% positive predictive value). METHODS Data were culled from individual lungs of 532(More)
PURPOSE The purpose of this investigation was to evaluate the diagnostic accuracy of radionuclide scintigraphic lung scans and clinical assessment in critically ill patients with suspected acute pulmonary embolism. MATERIALS AND METHODS Critically ill patients were defined as follows: (1) patients who were hypoxemic on room air, and not given ventilatory(More)
PURPOSE The purpose of this investigation was to determine the frequency of future pulmonary embolism (PE) among patients in whom PE was suspected and excluded by pulmonary angiography. METHODS Data are from the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED). The present investigation includes 380 patients in whom PE was excluded by(More)
PURPOSE The purpose of this investigation was to evaluate measured asymmetry of the calves in the assessment of patients with suspected pulmonary embolism (PE). METHODS Patients randomized for pulmonary angiography in the collaborative study of the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) were evaluated. Only patients in whom the(More)
PURPOSE The purpose of this investigation was to determine the frequency of pulmonary embolism (PE) in a single lung that showed a normal ventilation/perfusion (V/Q) lung scan when the V/Q scan on the contralateral side was interpreted as non-high-probability for PE. METHODS Data are from the national collaborative study Prospective Investigation of(More)
UNLABELLED This investigation assessed the positive predictive value of matched ventilation/perfusion (V/Q) and chest radiographic defects (triple-matched defects) for the detection of acute pulmonary embolism (PE). METHODS Data are from the Prospective investigation of Pulmonary Embolism Diagnosis (PIOPED). Only patients randomized for obligatory(More)
