Susceptibility weighted imaging (SWI), originally called BOLD venographic imaging, is an MRI sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. SWI uses a fully flow compensated, long echo, gradient recalled echo (GRE) pulse sequence to acquire images.

Axial FLAIR shows hydrocephalus, with magnetic susceptibility artifact from the implant producing abnormal signal in the subarachnoid spaces. References:

The magnetic susceptibility effect is increased with the magnetic field strength, leading to a greater impact on image spatial encoding and contrast formation. Such artifacts are the brightest in the long echo and gradient echo (GE) sequences of the gradient response. Artifact correction [5, 18, 19]: Magnetic susceptibility artifact Magnetic susceptibility artifacts are the result of micro-scopic gradients of the magnetic field strength at the interfaces of regions of different magnetic susceptibility.

2.3.1 Introduction: Sources of Susceptibility Artifacts . The uniformity of the B 0 main field in magnetic resonance imaging (MRI) is critical for artifact-free image formation. In MRI, susceptibility artifacts are caused for example by medical devices in or near the magnetic field or by implants of the patient. These materials with magnetic susceptibility distort the linear magnetic field gradients, which results in bright areas (misregistered signals) and dark areas (no signal) nearby the magnetic material. Magnetic susceptibility artifact has been documented with various implants and devices, which require appropriate identification with screening of patients prior to subjecting them to magnetic resonance examination. PURPOSE: To determine whether magnetic susceptibility artifact on magnetic resonance (MR) images can be used to grade gliomas.
