What is a common non-invasive method for evaluating the integrity of the uterus in a woman with suspected ectopic pregnancy?

Pelvic ultrasound is a common non-invasive method used to evaluate the integrity of the uterus, particularly in the context of suspected ectopic pregnancy. This imaging technique allows healthcare providers to visualize the uterus and surrounding structures, helping to confirm or rule out ectopic pregnancy by detecting whether a fetus is located within the uterine cavity or in an abnormal location, such as the fallopian tubes.

Pelvic ultrasound is preferred due to its accessibility, safety (no radiation exposure), and effectiveness in providing immediate answers in an emergency setting. It can show the presence of an intrauterine gestational sac, and if the sac is not located within the uterus, it raises suspicion for ectopic pregnancy, warranting further evaluation and management.

Other imaging options, like magnetic resonance imaging and computed tomography, are less commonly utilized for this purpose due to their increased cost, longer time for results, and, in the case of computed tomography, exposure to radiation, which is not ideal for assessments involving potential pregnancy complications. Hysteroscopy, while useful for direct visualization of the uterine cavity, is an invasive procedure and not typically used as a first-line evaluation for suspected ectopic pregnancy. Hence, pelvic ultrasound remains the preferred choice for its effectiveness, safety, and non-invasive nature
