The significance of a single area of ventilation/perfusion (V/P) mismatch in lung scans
performed on patients suspected of pulmonary embolism (PE) was evaluated. Ten of 20 …

We performed a retrospective evaluation of the data obtained from the Prospective
Investigation of Pulmonary Embolism Diagnosis (PIOPED) study to determine the …

Ventilation-perfusion lung scans demonstrating two or more areas of VP mismatch (MM) are
considered by most nuclear medicine physicians to indicate a high probability of pulmonary …

Controversy exists as to whether patients with single segmental mismatch (SSM) on a
ventilation/perfusion (VQ) lung scan should be given a low or an intermediate probability of …

DISCUSSION A perfusion scan accurately reflects the regional distribu tion of pulmonary
blood flow. However, because almost any pulmonary disease, vascular or parenchymal …

The segmental ventilation-perfusion mismatch is almost invariably a sign of pulmonary
embolism (PE). As ventilation scintigraphy is an expensive and time-consuming procedure …

The accurate diagnosis of pulmonary emboli remains a perplexing problem. Perfusion lung
scanning while sensitive is not specific. The addition of ventilation scanning to perfusion …

The results of ventilation-perfusion (VQ) imaging and pulmonary angiography were
retrospectively analyzed in 146 patients with suspected pulmonary embolism (PE) to define …

Background: To determine the optimal diagnostic cut‐off point using a simplified criterion for
the detection of pulmonary embolus (PE) and to evaluate the criterion's utility and reporter …

Purpose The authors' goal was to determine whether the prevalence of pulmonary embolism
in patients with matching ventilation–perfusion (V–Q) defects and chest radiographic …
