There is a constantly evolving knowledgebase regarding the safety of MRI in pregnant patients, as well as the safety of gadolinium administration, given potential fetal risks. This review provides an overview of national and international recommendations for patient screening and safety by trimester, evaluates the most recent literature regarding administration of gadolinium in pregnant patients, and discusses technical requirements when imaging pregnant patients. A protocol for imaging… 
Non-obstetric Complications in Pregnancy: Role of Imaging
Imaging evaluation of the pregnant patient for non-obstetrical symptoms or complication is challenging because of the effects of radiation on the developing fetus, and careful consideration has to be given to tailor the examination to the clinical symptoms.

MRI in Pregnancy and Precision Medicine: A Review from Literature
A literature review focusing on contrast and non-contrast MRI use during pregnancy found that long circulating liposomal nanoparticle-based blood-pool gadolinium contrast agents that do not penetrate the placental barrier and therefore do not expose the fetus to the contrast agent during pregnancy, preserving it from any hypothetical risks.
How Could Nanomedicine Improve the Safety of Contrast Agents for MRI during Pregnancy?
This review will recapitulate the most common non-obstetrical, obstetrical, and fetal indications for magnetic resonance imaging on pregnant women, and possible advantages of nanostructured contrast agents compared to current molecular ones are explored.
Safe and pivotal approaches using contrast-enhanced ultrasound for the diagnostic workup of non-obstetric conditions during pregnancy, a single-center experience
The results demonstrate safe and crucial application of off-label CEUS in pregnant women to assess different non-obstetric conditions allowing to prevent additional ionizing CT or application of (gadolinium-based) contrast agent in MRI.
Contrast-Enhanced Ultrasound for Assessing Abdominal Conditions in Pregnancy
Off-label use of CEUS showed an excellent safety profile allowing the avoidance of ionizing radiation exposure as well as contrast agents in case of CT or use of gadolinium-based contrast agentsIn case of MRI.

Standard MRI protocols and the use of intravenous contrast will be described, and several examples will be provided of the application of MRI in the assessment of the acute abdomen.
Role of Ultrasound in the Assessment and Differential Diagnosis of Pelvic Pain in Pregnancy
Pelvic pain (PP) is common in pregnant women and can be caused by several diseases, including obstetrics, gynaecological, gastrointestinal, genitourinary, and vascular disorders. Timely and accurate
Fetal Cardiovascular MRI - A Systemic Review of the Literature: Challenges, New Technical Developments, and Perspectives.
Fetal MRI is a safe imaging method with no developmental impairments found to be associated with in utero exposure to MRI, and new fetal CMR techniques successfully applied to achieve high-quality morphologic and functional imaging as well as quantitative assessment of fetal hemodynamics in research settings.


Techniques, terminology, and indications for MRI in pregnancy.
A review of current evidence supports the following indications for fetal MRI: suspected central nervous system anomalies, neck and oropharyngeal masses, diaphragmatic hernia, abdominal masses or bowel pathology not fully characterized by ultrasonography, and suspected fetal infection.
Safety of Contrast Material Use During Pregnancy and Lactation.
Imaging of pregnant and lactating patients: part 2, evidence-based review and recommendations.
Diagnostic imaging should be performed during pregnancy only with an understanding of the maternal and fetal risks and benefits, the comparative advantages of different modalities, and the unique anatomic and physiologic issues associated with pregnancy.
MR safety issues particular to women.
Quality initiatives: guidelines for use of medical imaging during pregnancy and lactation.
The use of iodinated contrast agents is generally safe during pregnancy; nevertheless, these agents should be used with caution due to the risk of fetal hypothyroidism and should be administered only when the clinical situation clearly requires doing so.
Acute abdominal and pelvic pain in pregnancy: ESUR recommendations
New guidelines based on the current literature and on the accumulated clinico-radiological experience of the European Society of Urogenital Radiology (ESUR) working group are proposed for imaging these suspected conditions.

The role of sonography in evaluation of acute abdomen during pregnancy is reviewed and sonographic findings of various maternal complications that can present with acute abdominal pain in pregnant patients are shown.
MR imaging of maternal diseases of the abdomen and pelvis during pregnancy and the immediate postpartum period.
Until more conclusive safety data become available, MR imaging should be reserved for cases in which results of ultrasonography are inconclusive and patient care depends on further imaging.
MRI of acute abdominal and pelvic pain in pregnant patients.
The intrinsic safety of MRI and its ability to accurately show abdominal and pelvic disease in pregnant patients make it highly useful in the evaluation of these patients.
