Abstract
A pulse sequence is presented for performing localized lactate-edited proton spectros-copy in the whole-body environment. The sequence is optimized for relatively low field strength (1.5-T) clinical measurements. Characteristics of this method of lactate editing, which makes it more suitable for clinical applications than previous methods, include the following: The “one shot” nature of the method makes it relatively insensitive to patient motion; water suppression is high as all 90° pulses are binomial pulses; and very narrow band rf pulses, such as used in high-field lactate-editing sequences, but which are necessarily very long at low fields, are not required. Further, this lactate editing scheme can be very easily combined with localized spectroscopic measurements. © 1988 Academic Press, Inc.
