Researchers have found that over a 10-year period radiologic exams on pregnant women have more than doubled, according to a study published in the online edition of Radiology.
"Imaging utilization has not been previously studied in the pregnant population," said Elizabeth Lazarus, M.D., assistant professor of diagnostic imaging at the Warren Alpert School of Medicine at Brown University and a radiologist at Rhode Island Hospital in Providence, R.I. "This population may be vulnerable to the adverse effects of radiation."
Dr. Lazarus and colleagues conducted a retrospective review of nuclear medicine, CT, fluoroscopy and plain-film x-ray imaging examinations performed at Rhode Island Hospital and Women and Infants' Hospital from 1997 through 2006 to determine how often these imaging exams were performed on pregnant women and the estimated radiation dose to the fetus. Data were then compared to the number of infant deliveries per year for that same time period.
