Abstract

It is demonstrated that the stability of the Carr‐Purcell‐Mei‐boom‐Gill (CPMG) sequence reflects the existence of a steady state solution to the Bloch equations in the absence of T~2~ and T~1~ decay. The steady state theory is then used to evaluate the performance of low flip angle RARE imaging sequences with both constant and optimally varied refocusing flip angles. The theory is experimentally verified in phantoms and then optimized, single shot, low flip angle RARE is used to obtain artifact‐free images from the brain of a normal volunteer.

Expressions for the contrast-to-noise ( C / N ) behavior in images obtained from rapid low flip-angle excitation pulses are derived, taking into account both TI-and T,-dependent contrasts. It is shown, and demonstrated experimentally, that images with T2-weighted contrasts can be efficiently acquire

## Abstract A new ultra‐fast imaging technique that does not place extreme demands on the speed of the gradient system is described. When used with comparable MRI systems, the rotating ultra‐fast imaging sequence (RUFIS) can acquire images 4 to 5 times faster than gradient‐moment nulled EPI and mor

## Abstract AFI (actual flip angle imaging) represents an interesting approach to map the __B__~1~ transmit fields by measuring the spatial variations of the effective flip angle. However, the accuracy of the technique relies on the adequate spoiling of transverse magnetization. In the present work
