Gibbs and truncation artifacts | Radiology Reference Article | Radiopaedia.org
Gibbs artifact, also known as truncation artifact or ringing artifact, is a type of MRI artifact. It refers to a series of lines in the MR image parallel to abrupt and intense changes in the object at this location, such as the CSF-spinal cord and the skull-brain interface.. The MR image is reconstructed from k-space which is a finite sampling of the signal subjected to inverse Fourier transform in order to obtain the final image. At high-contrast boundaries (jump discontinuity in mathematical terms), the Fourier transform corresponds to an infinite number of frequencies. Since MR sampling is finite, the discrepancy is manifest in the reconstructed image in the form of a series of lines. These can appear in both phase-encode and frequency-encode directions.. The more encoding steps, the less intense and narrower the artifacts. Figure 1 shows the Gibbs effects resulting from Fourier transforming a sharp change in image intensity. Figure 2 shows prominent light and dark line along the sides that ...
Magnetic field | Radiology Reference Article | Radiopaedia.org
The magnetic field describes the influence a magnet has on its surrounding area. Magnets create a magnetic field or line of force running from the magnetic north to the magnetic south pole of the magnet. Magnetic fields are the result of intrinsic magnetic moments and moving electric charges within a material. In MRI the strength of the main magnetic field (B0) is measured in tesla (T) or, historically, gauss (G), where 1 tesla equals 10,000 gauss.. ...

Controversies in Diagnostic Imaging: Contrast-Induced Nephropathy - Peter Steinberg
As to why iopamidol would have a lower risk of CIN than iohexol, a clear mechanistic explanation is lacking. Each agent has a ... This hypothesis was based on the fact that in the trials which failed to show a benefit of IOCM compared to LOCM, iopamidol ( ... 2009). "Nephrotoxicity of iodixanol versus iopamidol in patients with chronic kidney disease and diabetes mellitus undergoing ... iopamidol and iodixanol use resulted in similar rates of CIN. However, key differences were noted between the two trials. For ...
