Investigative Radiology November 2021

During the last decade, metal artifact reduction in magnetic resonance imaging (MRI) has been an area of intensive research and substantial improvement. The demand for an excellent diagnostic MRI scan quality of tissues around metal implants is closely linked to the steadily increasing number of joint arthroplasty (especially knee and hip arthroplasties) and spinal stabilization procedures [...]

The aim of this study was to investigate the impact of a novel iterative denoising and image enhancement technique in T1-weighted precontrast and postcontrast volume-interpolated breath-hold examination (VIBE) of the abdomen on image quality, noise levels, and diagnostic confidence without change of acquisition parameters. [...]

New next-generation low-field magnetic resonance imaging systems (operating in the range of 0.5 T) hold great potential for increasing access to clinical diagnosis and needed health care both in developed countries and worldwide. The relevant history concerning the choice of field strength, which resulted in 1.5 T still dominating today the number of installed systems, is considered, together with design advances possible because of interval developments, since low field was considered for clinical use in the 1980s, and current research. The potential impact of low-cost, advanced-generation low-field magnetic resonance imaging systems, properly designed, is high in terms of further dissemination of health care—across the gamut from industrial to developing countries—regardless of disease entity and anatomic region of involvement, with major niche applications likely as well.
