Surface Coils an mri of liver Technical Factors, Phased-array surface coils provide on average a three-fold improvement in SNR and should be considered essential for optimal imaging of the abdomen and liver. New technical developments include
increased numbers of coil receiver elements associated with magnets that are engineered with a greater number of receiver channels. In combination with parallel processing techniques such as SENSE and SMASH. these represent methods that use coil element sensitivity profiles to obtain spatial information that can lead to reduced acquisition times for gradient echo imaging. As the number of coil elements and receiver channels are increased, the degree of acceleration may be in reased.
In addition, improved coil system designs facilitate more rapid imaging of multiple body regions in combination, such as the abdomen and pelvis.
