All patients are reviewed for contraindications prior to MRI scanning.

A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.
Interventional magnetic resonance imaging, also interventional MRI or IMRI, is the use of magnetic resonance imaging (MRI) to do interventional radiology procedures.. Because of the lack of harmful effects on the patient and the operator, MR is well suited for "interventional radiology", where the images produced by an MRI scanner are used to guide a minimally-invasive procedure ...
The procedure is often well tolerated and can result in a permanent reduction or elimination of symptoms.

However, there are ...
That means arctic air is blasting over the US, while pressure changes and the motion of the polar vortex whip up high winds and create a perfect recipe for wintry weather.
