V Q Scanning Using Spect And Spect Ct Journal Of Nuclear Medicine Planar ventilation–perfusion (v q) scanning is often used to investigate pulmonary embolism; however, it has well recognized limitations. spect overcomes many of these through its ability to generate 3 dimensional imaging data. v q spect has higher sensitivity, specificity, and accuracy than planar imaging and a lower indeterminate rate. spect allows for new ways to display and analyze data. Abstract. planar ventilation perfusion (v q) scanning is often used to investigate pulmonary embolism; however, it has well recognized limitations. spect overcomes many of these through its ability to generate 3 dimensional imaging data. v q spect has higher sensitivity, specificity, and accuracy than planar imaging and a lower indeterminate rate.
V Q Scanning Using Spect And Spect Ct Journal Of Nuclear Medicine Ventilation–perfusion (v q) spect imaging has also been consistently shown to have a much lower indetermi nate rate than planar imaging, typically less than 5% (8,15–19). leblanc et al. demonstrated that spect has a very high negative predictive value (98.5%) for pe (20). in that study of 108. table 1. Planar ventilation–perfusion (v q) scanning is often used to investigate pulmonary embolism; however, it has well recognized limitations. spect overcomes many of these through its ability to generate 3 dimensional imaging data. v q spect has higher sensitivity, specificity, and accuracy than planar imaging and a lower indeterminate rate. spect allows for new ways to display and analyze data. Spect ct in v q scanning. combining the functional data provided by single photon emission computed tomography (spect) with the anatomical information provided by ct has been shown to improve overall diagnostic accuracy in many areas of nuclear medicine. although planar lung scans have often relied on correlation with a chest x ray to help. Any nuclear medicine department equipped with a modern hybrid scanner can now perform combined v q spect with ct (using low dose protocols) to further enhance diagnostic accuracy and allow for new ways to display and analyze data, such as parametric v q ratio images. planar ventilation–perfusion (v q) scanning is often used to investigate pulmonary embolism; however, it has well recognized.

Lung scintigraphy, or ventilation perfusion (v q) scan, is one of the commonly performed studies in nuclear medicine. owing to variability in clinical applications and different departmental workflows, many trainees are not comfortable interpreting the results of this study. this article provides a simplified overview of v q imaging, including a review of its technique, interpretation methods.
