British scientist (1933-) who shared the 2003 Nobel Prize for Physiology or Medicine with the American scientist Paul C. Lauterbur for discoveries concerning “magnetic resonance imaging.” (Magnetic resonance imaging is better known perhaps as MRI). Mansfield did his research principally at the University of Nottingham.
Sir Peter Mansfield developed the utilization of gradients in the magnetic field. He showed how the signals could be mathematically analyzed, which made it possible to develop a useful imaging technique. Mansfield also showed how extremely fast imaging could be achievable. This became technically possible within medicine a decade later.
Mansfield utilized gradients in the magnetic field in order to more precisely show differences in the resonance. He showed how the detected signals rapidly and effectively could be analyzed and transformed to an image. This was an essential step in order to obtain a practical method. Mansfield also showed how extremely rapid imaging could be achieved by very fast gradient variations (so called echo-planar scanning). This technique became useful in clinical practice a decade later.
- M. intercellulare
- M protein
An antibody or part of an antibody found in unusually large amounts in the blood or urine of patients with multiple myeloma, a form of cancer that arises in plasma cells (white blood cells that produce antibodies).
- Map, contig
A map depicting the relative order of a linked library of small overlapping clones representing a complete chromosome segment. A contig is a chromosome map showing the locations of those regions of a chromosome where contiguous DNA segments overlap. Contig maps are important because they provide the ability to study a complete, and often large, […]
- Map, cytogenetic
A genetic term referring to the visual appearance of a chromosome when stained and examined under a microscope. Particularly important are visually distinct regions, called light and dark bands, which give each of the chromosomes a unique appearance. This feature allows a person’s chromosomes to be studied in a clinical test known as a karyotype, […]
- Map, linkage
A map of the genes on a chromosome based on linkage analysis. A linkage map does not show the physical distances between genes but rather their relative positions, as determined by how often two gene loci are inherited together. The closer two genes are (the more tightly they are linked), the more often they will […]
