## Abstract The presence, size, structure and clustering characteristics of microcalcifications can indicate breast cancer. The magnetic susceptibility of microcalcifications differs from soft biological tissues, leading to directional blurring effects that can be detected by statistical image proc

Abstract
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. We performed cardiovascular magnetic resonance (CMR) examination of the aorta in a 24βyearβold woman in the setting of repaired aortic coarctation, and found magnetic susceptibility artifact arising from the stomach in the absence of known susceptibility artifactβproducing material in this region. Further history revealed that she had ingested a prenatal vitamin prior to imaging, prompting experimental analyses that led us to conclude that ironβcontaining vitamins may be a source of magnetic susceptibility artifact.

## Abstract ## Purpose To compare image quality, artifacts, and signalβtoβnoise ratio (SNR) in cardiac cine TrueFISP magnetic resonance imaging (MRI) with and without parallel acquisition techniques (PAT). ## Materials and Methods MRI was performed in 16 subjects with a TrueFISP sequence (1.5 T;
Magnetic resonance imaging (MRI) is an indispensable tool for musculoskeletal imaging. The presence of metal, however, raises concerns. The potential risks are loosening and migration of the implant, heating of the metal with surrounding tissue, causing thermal damage, and artifactual distortion whi
In magnetic resonance imaging (MRI), T\* 2 -weighted contrast is significantly enhanced by extremely high magnetic field strength, offering broad potential applications. However, the T\* 2 -weighted image contrast distortion and signal loss artifact arising from discontinuities of magnetic susceptib
A computer software technique has been developed and employed to insert a modified-Wiener-deconvolution filter (an optimal filter) immediately following the quadrature detector of a magnetic resonance imager. The purpose of this effort is to try to suppress the undesirable effect of the noise found
