Reporting ventilation-perfusion lung scintigraphy: impact on subsequent use of anticoagulation therapy.

Reporting ventilation-perfusion lung scintigraphy: impact on subsequent use of anticoagulation therapy.

Ventilation and perfusion lung scintigraphy is an established and safe noninvasive technique which has been used for nearly 30 years to establish the diagnosis of pulmonary embolism. Recently, in common with other diagnostic tests, there has arisen the need to reassess the effectiveness of this test in the clinical setting. A retrospective analysis of 244 patients undergoing ventilation-perfusi...

Spurious lung perfusion ventilation defect on planar ventilation-perfusion scan detected by SPECT imaging

Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...

Ventilation/perfusion lung scintigraphy. Multiple applications besides pulmonary embolism.

Ventilation/perfusion scintigraphy is the diagnostic tool of choice for detection and monitoring of pulmonary embolism. However, the knowledge on its value for other or concurrent pathologies is poor. In this review scintigraphic characteristics of the main pathologies, interpretation and artefacts are described. Together with the understanding of pathophysiology of the lung, the potential gain...

Tomographic ventilation-perfusion lung scintigraphy in cardiopulmonary disease

How to use a gestalt interpretation for ventilation-perfusion lung scintigraphy.

UNLABELLED The use of a so-called gestalt interpretation, an integration of different sets of criteria and the physician's own experience, has been advocated in the interpretation of lung scintigraphs of patients with clinically suspected pulmonary embolism. However, data on the reliability of this approach are limited. The aim of this study was to investigate the observer variability and accur...
