In brief: Not realy very
Ventilation/perfusion scan (v/q scan or lung scintigraphy), which shows that some areas of the lung are being ventilated but not perfused with blood (due to obstruction by a clot).
This type of examination is used less often because of the more widespread availability of ct technology, however, it may be useful in people who have an allergy to iodinated contrast or in pregnancy. Thanks.

In brief: Agree with Dr Hadied
The problem with VQ scans is the images they provide are often rather non-specific.
When someone has a history that is strongly suggestive of a pulmonary embolism and there is a high probability scan, then the results are quite accurate. The problem is that doesn't happen terribly often. Ct scans of the chest are far more reliable.
