Magnetic resonance imaging is an effective means of diagnosing acute abdominal and pelvic pain in pregnant patients, and it avoids fetal exposure to the radiation of a computerized axial tomography exam, Katherine Birchard, M.D., and her colleagues have reported.
Although there have been no documented cases of MRI causing adverse effects to the fetus, MRI scans should be used in pregnant patients only when the benefits clearly outweigh the risks, the researchers said. "However, we should stress that the single greatest factor in morbidity and mortality of the pregnant patient is delay in diagnosis," reported Dr. Birchard of the University of North Carolina, and associates (AJR Am. J. Roentgenol. 2005;184:452-8).
The researchers retrospectively analyzed all MRI studies of 29 pregnant patients referred to their facility from 2002 to 2004 for evaluation of acute abdominal or pelvic pain. The patients' mean age was 25 years (18-35 years), and mean gestational age was 23 weeks (10-36 weeks). Most of the patients (22) did not have gadolinium administered.
Every patient underwent fetal sonography before any other imaging. Six also underwent complete abdominal sonographic examination before the ...
