Summary
Multiple-fetus gestations carry higher risks for anomalies and growth issues. Imaging with ultrasound and fetal MRI is crucial for managing complicated twin pregnancies, especially those sharing a placenta.
Area of Science:
- Maternal-fetal medicine
- Diagnostic imaging
- Perinatology
Background:
- Multiple-fetus gestations have higher risks of discordant anomalies, aneuploidy, and growth restriction than singleton pregnancies.
- Twins sharing a placenta face unique conditions requiring potential surgical intervention.
- Current diagnostic approaches may necessitate advanced imaging modalities.
Purpose of the Study:
- To outline guidelines for imaging complicated multiple-fetus gestations.
- To emphasize the role of fetal MRI in conjunction with ultrasound.
- To aid in the evaluation and management of high-risk twin pregnancies.
Main Methods:
- Review of imaging techniques for multiple-fetus gestations.
- Focus on ultrasound (US) and fetal magnetic resonance imaging (MRI).
- Guidelines for the 2nd and 3rd trimesters of complicated pregnancies.
Main Results:
- Identified specific risks associated with multiple-fetus gestations, particularly monochorionic twins.
- Highlighted the complementary roles of US and fetal MRI in diagnosis.
- Provided a framework for imaging protocols in complex cases.
Conclusions:
- Complicated multiple-fetus gestations require comprehensive imaging strategies.
- Fetal MRI is a valuable tool for evaluating conditions not fully assessed by ultrasound alone.
- Standardized imaging guidelines can improve patient management and outcomes.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
