Body Imaging: MRI Protocols, Imaging Parameters, and Graphical Prescriptions
Until recently, body imaging was the domain of multislice CT and ultrasound for most applications because of its very short acquisition time, higher resolution, and widespread availability. However, thanks to the recent sequence, coil and MR hardware advances, MR became a powerful imaging modality due to its inherent multiple tissue contrast, safer scanning ability, and its ability to visualize anatomy. The main disadvantage of MR imaging is longer scan time. However, with the multichannel coil structures and parallel imaging concept, both image quality and routine MR examination times improved significantly and will continue to improve.
