Objective: The objective of the study was to determine the incidence of central venous catheter-related complications during pregnancy and postpartum.
Study Design: This was a retrospective case series of patients admitted for obstetric care and who had a central venous catheter placed between Jan. 1, 2000, and July 10, 2006.
Purpose: To calculate mean fetal radiation dose from helical chest computed tomography (CT) by using maternal-fetal geometries obtained from healthy pregnant women and to compare the calculated CT doses with the fetal doses reported with scintigraphy.
Materials And Methods: Maternal-fetal geometries were determined in 23 pregnant women with varying body mass index and fetal gestational age. Monte Carlo techniques were used to estimate the dose that would be received by each fetus from CT scanning performed with the following parameters: 120 kVp; 100 mA; scanning time, 1 second per section; collimation, 2.
