Inferior vena cava (IVC) filters are percutaneously inserted intravascular devices to trap clots arising in the peripheral venous system so they do not reach the heart. The original "classic" device was the stainless steel Greenfield™ filter developed in 1973.

Nov 19, 2007 · Safe MR imaging involves a careful initial patient screening, accurate determination of the permanent implanted or temporary cardiovascular device and its properties, a thoughtful analysis of the risks and benefits of performing the examination at that time, and, when indicated, appropriate physician management and supervision.

Mar 12, 2015 · In this article, the authors review the spectrum of IVC variants and pathologic processes and the relevant findings from magnetic resonance imaging, angiography, sonography, and positron emission tomography.

Inferior vena cava (IVC) filters are commonly used in patients at risk for life-threatening pulmonary embolism. Since the Mobin-Uddin filter was introduced in 1967, numerous other IVC filters have been developed.

Inferior vena cava (IVC) filters are commonly used in patients who are at risk for life-threatening pulmonary embolism. After the introduction of permanent devices, numerous retrievable and convertible designs became available. Inaccurate identification can lead to confusion in options for filter retrieval and anticoagulation. CONCLUSION.

Multiplanar reformatted image through the inferior vena cava using three-dimensional respiratory-gated bSSFP demonstrates a widely patent inferior vena cava (asterisk). The superior mesenteric vein and portal confluence are also depicted (arrow).

Currently available IVC filters, OTHER THAN the Bird’s Nest filter are MR permissible immediately after implantation; IVC filters implanted for more than 6 weeks do not require additional precautions; Bird’s Nest filter: MR permissible 6 weeks after implantation. Any exceptions are at the discretion of the radiologist; Bottom Line: MRI ...
