Abstract

Signal intensity in magnetic resonance imaging (MRI) is described by the solution to the Bloch equations. Image behavior is calculated for the variable-angle gradient refocusing and conventional spin-echo techniques. It is found that by proper manipulation of the excitation angle (and echo time in spin-echo sequences), the imaging time can be reduced up to twentyfold for the gradient refocusing technique and fourfold for the conventional spin-echo imaging. The contrast obtained is comparable to that acquired in conventional MRI. Imaging experiments performed on phantoms and human heads are in good agreement with theoretical results.
