Some authorities recommend lower extremity venous compression ultrasonography as the next test because if DVT is present, anticoagulant treatment will be the same as for PE, and venous compression ultrasonography avoids fetal radiation exposure.12,28, When d-dimer testing and venous compression ultrasonography are inconclusive, multidetector-row (spiral) computed tomography has become the test of choice for diagnosing PE in pregnancy.12,24,26 Single-slice computed tomography is inadequate in diagnosing peripheral PE, but newer-generation spiral computed tomography, tested in nonpregnant patients, has shown positive and negative predictive values comparable with pulmonary angiography.27 Fetal exposure to radiation is lower with spiral computed tomography than with ventilation-perfusion (V/Q) scanning (less than 130 Gy and 370 Gy, respectively), and fetal exposure to spiral computed tomography nonionic contrast appears safe.29 Spiral computed tomography does expose the maternal breast to greater radiation, and V/Q scanning may be preferred in women with a family history of breast cancer.12 A cost-benefit analysis supports spiral computed tomography as the preferred test for diagnosing PE during pregnancy.30.
