Webb18 apr. 2024 · Fiaschetti et al. reported motion as the most common cause of artifacts in breast MRI, with motion artifacts present in 16% of their 630 cases. The low frequency of moderate and marked artifacts in our group is likely related to strict patient preparation in our department, stressing the importance of talking to the patients before the … Webb18 juni 2024 · Fat-water swapping is an artifact specific to chemical shift encoded MRI and so-called Dixon methods. It is more frequent using the 2-point than the multi-point (> 2) Dixon method. Actually, fat-water swapping on the 2-point Dixon sequences partly triggered the development of the multi-point techniques. Fat-water swapping occurs on post …

This will cause a modification in contrast and/or a loss of signal through partial saturation in the slice or zone of intersection. These phenomena are even more pronounced with pulses of 180° (inversion recovery, fast spin echo).
