Gadolinium is considered a pregnancy category C drug (it should be administered only if the potential benefit outweighs the risk) because animal studies have revealed adverse effects. Among 26 patients who had exposure to gadopentetate-dimeglumine in the periconceptional and first trimester period, only one congenital birth anomaly was found (hemangiomas) [3]. However, no well-controlled studies of the teratogenic effects of these media in The American College of Radiology seeks and encourages collaboration with other organizations on the development of the ACR Appropriateness Criteria through representation of such organizations on expert panels. Participation on the expert panel does not necessarily imply endorsement of the final document by individual contributors or their respective organization. Reprint requests to: publications@acr.org Acute Pelvic Pain in the Reproductive Age Group pregnant patients have been performed. Thus, if the information requested from the MRI study with intravenous (IV) contrast cannot be acquired using other modalities and is needed to potentially affect the care of the patient or fetus during the pregnancy, and the ordering physician believes that it is not prudent to wait until the patient is no longer pregnant, IV contrast may be administered and the rationale diligently documented. It is recommended that informed consent be obtained from the patient after discussion with the referring physician [4]. Acute Pelvic Pain in the Reproductive Age Group Generally, MRI of the pelvis may provide sufficient anatomic coverage without including the entire abdomen as with MRI of the abdomen and pelvis and, thus, may be used in selected cases as a second-line imaging modality. Cesarean scar pregnancy was accurately diagnosed in 95.5% of cases using contrast-enhanced MRI compared with 88.6% using US in a retrospective analysis of 44 patients with cesarean section scar pregnancy.
