“…3T MRI provides a better signal to noise ratio and contrast to noise ratio compared with 1.5T imaging. This can result in a better spatial resolution and acquisition time or both [9,10]. Better signal to noise ratio and contrast to noise ratio also improve the visualisation of cartilage and quantification of cartilage volumes [11].…”

Whole-body MR tomography at 3 T is moving steadily from research into routine clinical practice. The most important advantage of high-field MRI is the higher signal to noise ratio, which allows acquisitions in the musculo-skeletal system with higher resolution within the same scan time. The imaging of small joints, the visualization of labral anatomy and pathology in the shoulder and hip joints, as well as cartilage imaging will benefit from higher resolution protocols. In addition to improved morphological imaging of articular cartilage, the higher sensitivity of 3 T allows the clinical use of advanced MR techniques of cartilage such as T1 and T2 mapping, diffusion and sodium imaging. The improved spectral resolution with the higher field may improve metabolic imaging of tumors of the skeleton and soft tissues.

“…In the new century, whole-body MRI systems operating at field strengths below 1.5T have generally lost popularity, while 3T MRI systems have been introduced into routine clinical practice in increasing numbers. As clinical 3T imaging has emerged, papers describing its general clinical use (14 -17) and specific advantages for vascular (18 -21), brain (22)(23)(24), musculoskeletal (25)(26)(27), and body (28) imaging have been published.…”

Clinical MRI at a field strength of 3.0T is finding increasing use. However, along with the advantages of 3.0T, such as increased SNR, there can be drawbacks, including increased levels of imaging artifacts. Although every imaging artifact observed at 3.0T can also be present at 1.5T, the intensity level is often higher at 3.0T and thus the artifact is more objectionable. This review describes some of the imaging artifacts that are commonly observed with 3.0T imaging, and their root causes. When possible, countermeasures that reduce the artifact level are described.
