Lung Scan

Ventilation and Perfusion Scan

What Affects the Test

Factors that can interfere with your test and the accuracy of the results include:

• Pregnancy. A lung scan is not usually done during pregnancy because the radiation could damage the developing baby (fetus).
• Barium and bismuth. If a lung scan is needed, it should be done before any tests that use barium (such as a barium enema).
• The inability to remain still during the test.
• Medical conditions, such as pulmonary edema or chronic obstructive pulmonary disease (COPD), that involve the lungs or heart.
