Magnetic resonance imaging of common, uncommon, and rare implantation sites in ectopic pregnancy.

OBJECTIVE: To review the MRI appearances of tubal and non-tubal implantation sites in ectopic pregnancy.

CONCLUSION: Transvaginal ultrasound is the primary imaging modality in ectopic pregnancy and MRI is used as a problem-solving tool in selected indications as detailed in the article. MRI features of tubal, interstitial, cervical, cesarean scar, cornual, ovarian, abdominal, and heterotopic pregnancies are provided to familiarize the radiologists with their appearances thereby assisting them in making early and accurate diagnosis.
