Magnetic Resonance Imaging in Tubal and Non-tubal Ectopic Pregnancy

Emphasizes: The importance of early diagnosis of ectopic pregnancy. Explain imaging findings of tubal and non-tubal ectopic pregnancy. Emphasize on functions and protocols of MRI, key imaging functions on MRI and differential diagnosis. Abstract: Ectopic pregnancy is the leading reason for pregnancy-related death in the first trimester. Ectopic pregnancy is generally detected by medical, lab, and sonographic findings, with implantation most commonly situated in the ampullary part of the fallopian tube. Pregnancies that develop at unusual implantation sites, such as angular, interstitial, cornual, cervical, ovarian, cesarean scar, and stomach cavity pregnancies, may hardly ever take place. Although ultrasound is considered the primary pregnancy-related imaging method, it might not have the ability to highlight the implantation website in particular types of pregnancy. Magnetic resonance imaging (MRI) has acquired popularity as an imaging tool for evaluating pregnant patients, and it is used as an analytical tool in special situations, consisting of ectopic pregnancy. MRI can validate irregular implantation website, and differentiate rupture from nonrupture cases prior to management. Other benefits include lack of ionizing radiation, superb soft tissue contrast, and sensitivity sufficient for determining hemorrhage and its phases. This post sums up imaging findings in tubal and non-tubal ectopic pregnancy with a focus on the roles and procedures of MRI, essential MRI functions, and differential diagnosis.
