- Pediatric Imaging
Background:
- Gadolinium-based contrast agents (GBCAs) improve MRI accuracy and speed.
- Potential risks associated with GBCAs necessitate careful consideration.
- Understanding GBCAs is crucial for safe and effective pediatric MRI.
Purpose of the Study:
- To review GBCAs used in pediatric radiology.
- To discuss GBCA chemistry, safety, and clinical applications.
- To compare GBCAs with non-GBCA MRI contrast agents.
Main Methods:
- Literature review of GBCAs in pediatric radiology.
- Analysis of GBCA chemistry and regulatory status.

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...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

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,...
