“…On the contrary, trajectories proposed in the past years, such as spiral and conical-SPRITE [13], under-sample the frequency space introducing blurring into the image. The trade-off is in acquisition time, conical-SPRITE is faster than diagonal-SPRITE but such sequences are both limited from a duty cycle point of view.…”

“…A further method is based on Single Point Imaging (SPI), or Single Point Ramped Imaging with T1 Enhancement (SPRITE) techniques [11,12]. The SPRITE technique developed out of the solids NMR field, where research is being done into imaging solid materials such as Teflon tubing and concrete samples of different composition [13,14]. More recently it was applied in the clinic for sodium imaging of the brain [15].…”

Abstract:Many solid or semi-solid tissues have ultra-short or short T2* components that make them virtually "invisible" to standard MRI techniques. For this reason, methods such as ultra-short echo time (UTE) techniques were developed to investigate and detect some of these short and ultra-short time components. Here we report on the development and implementation of a novel version of the Single Point Ramped Imaging with T1 Enhancement (SPRITE) technique in order to image mouse models. The method, called diagonal-SPRITE, was optimized within hardware limitations such as duty cycle and gradient strength at high field. Preliminary in vivo MR T2* value of organs of normal mouse models and related T2* maps were generated. In addition, the sequence was applied to highlight stomach short T2* after the application of a long T2* suppression pulse and to achieve a positive contrast in a SPIO-labelled cells experiment.

“…The advantages of centric-scan SPRITE compared to previous implementations of SPRITE [17] are profound: simplified image contrast is achieved, faster, with a better signal to noise ratio and a reduced gradient duty cycle.…”

“…The French fry images were acquired with a 128 Â 128 Â 16 three dimensional Conical SPRITE sequence (Halse et al, 2003), using a multiple point acquisition. The sequence employed 39 cones and 274 interleaves, and acquired four points on the FID.…”
