The safe and accurate diagnosis of acute pulmonary embolism (PE) remains challenging, and many PE-related deaths still occur before the detection of PE. Current techniques detect PE as "negative images," ie, the absence of contrast or downs...

Single-photon emission computed tomography (SPECT) is being increasingly used as a tool in respiratory research, in particular ventilation SPECT. Much of the basic understanding of pulmonary physiology has been derived from inhaled radioact...

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 pl...

When considering the investigation of the patient with possible pulmonary embolism, one needs to balance the likelihood of disease and the diagnostic utility of the test against the risks associated with the investigation. Both computed tom...

Planar ventilation and perfusion (V/Q) scintigraphy has been largely displaced by computed tomography pulmonary angiography (CTPA) in recent years for the diagnosis of pulmonary embolism (PE). This change can be attributed to multiple studi...

Ventilation/perfusion single-photon emission computed tomography (V/Q SPECT) is the scintigraphic technique of choice for the diagnosis of pulmonary embolism and many other disorders that affect lung function. Data from recent ventilation s...

In this article we review protocols for ventilation-perfusion (V/Q) imaging with current generation technology. Although many groups have expressed interest in moving from planar lung V/Q imaging to single-photon emission computed tomograph...

Compared with planar imaging, ventilation/perfusion scintigraphy performed with single-photon emission computed tomography (SPECT) has a greater sensitivity and specificity, greater accuracy, improved reproducibility, and a lower number of ...
