title: Exclusion of monoamniotic twinning by contrast-enhanced computed tomography.
abstract: Monoamniotic twinning, through relatively rare, imposes a constant threat of adverse outcome upon twin pregnancy, at least until the third trimester. This report describes the use of contrast-enhanced computed tomography as one way to define or rule out the condition and proposes an optimal technique and timing for its utilization.
