- To review published data on the risks of radiation exposure in pregnancy from VQ scan or Chest CTA. - To summarize the current literature and recommendations regarding use of VQ or CTA for evaluation of pulmonary embolism in pregnancy. - To review protocols to optimize acquisition and interpretation of both studies in a pregnant patient.

1. Radiation risk during pregnancy with CTA and VQ will be compared.  2. Current literature and recommendations will be reviewed regarding:      -Choice of test for pregnant patients.      -Protocols for optimization of both tests in pregnant patients.

Making a confident diagnosis of pulmonary embolism is an important role of imaging. Anticoagulation carries significant risks, especially during pregnancy. However, minimizing radiation exposure is a concern for a pregnant patient. Evaluation for PE can be performed with either nuclear medicine ventilation/perfusion (V-Q scan) scan or CTA. At the end of the presentation, the reader will gain a better understanding of the comparative risks of nuclear medicine V-Q scan and CTA during pregnancy. The current recommendations on choice of test and methods to optimize both exams will also be discussed.
