All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
In patients who have been treated with a weakly ferromagnetic IVC filter (Gianturco bird nest IVC filter [Cook], stainless steel Greenfield vena cava filter [Boston Scientific]), it is advised that the patient wait at least six weeks before undergoing an MR examination (because these older devices initially may not be anchored as firmly in ...
The first to be so specified was the Medtronic Revo MRI SureScan, approved by the US FDA in February 2011, [30] which was the first to be specified as MR conditional. [31] [32] There are several conditions to use of MR Conditional pacemakers, including certain patients' qualifications and scan settings. An MRI conditional device has to have MRI ...

The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
MR elastography for detection of liver fibrosis in two patients. The left column shows the anatomy, with the liver outlined. The middle row shows images of propagating shear waves in the liver, captured with the MRE technique. The right column shows elastograms computed from the wave images, with tissue stiffness depicted with on color scale.
The Boston criteria version 2.0 [1] is a set of guidelines designed to diagnose cerebral amyloid angiopathy (CAA), a disease that affects small blood vessels in the brain, particularly those in the cortex and leptomeninges. Although the gold standard for diagnosis is histopathological examination, the Boston criteria provide clinicians with a ...
