Pulmonary imaging during pregnancy.

The diagnosis of pulmonary disorders associated with pregnancy is complicated by concerns about maternal/fetal radiation exposure, administration of contrast media, and medicolegal issues. This article reviews diagnostic imaging modalities, radiation exposure policy statements and provides a brief review of radiographic findings in selected pulmonary disorders associated with pregnancy. Clinicians should familiarize themselves with the benefit/risk of imaging modalities. Institution-specific imaging algorithms that minimize maternal/fetal radiation exposure are recommended. Institutional system-wide protocols would minimize confusion among healthcare providers.
