Physiological Side Effects of Fast Gradient Switching,ers, however, report unwanted side effects which are not of great concern for further research. All RF power used in MRI is converted into heat within the human tissue due to the conductivity of the tissue.

Echo-Planar Imaging on Small-Bore Systems,il bearing rock samples, and in the biomedical field for studying laboratory animals. While submil-limeter spatial resolution is needed in both of these fields, biomedical MRI has the additional need for efficient data collection, and in many cases motion insensitivity which can be met through the use of echo-planar imaging techniques.

Turbo Spin-Echo Imaging,the raw data needed for image formation are acquired in several consecutive passes instead of one. This segmentation has several advantages: shorter effective echo time, lower bandwidth, less T2 decay, and fewer artifacts.

Echo-Planar Magnetic Resonance Imaging of Human Brain Activation,r developing areas in fMRI: imaging platform or methodology development, contrast mechanism research, postprocessing development, and applications. In the areas of imaging platform development and contrast mechanism research, several examples demonstrating the utility of EPI are given.

Single Shot RARE,id spin echo (RARE) technique has as yet been installed only on a limited number of systems despite its useful clinical applications . This chapter discusses the problems in generating a long echo train under the conditions of a clinical MR system and presents an over
