The image-guided in vivo spectroscopic (ISIS) pulse sequence has been combined with a double-quantum-filter scheme in order to obtain localized and water-suppressed 1 H NMR spectra of J -coupled metabolites. The coherence-transfer efficiency associat

The goals of this study were to evaluate 31 P MR spectroscopic imaging (MRSI) for clinical studies and to survey potentially significant spatial variations of 31 P metabolite signals in normal and pathological human brains. In normal brains, chemical

Spectroscopic imaging of phosphorus metabolites in the human brain has been carried out with two data acquisition methods: by observation of the free induction decay (FID) signal and by a short spin echo sequence. The resultant spectral images and sp

The ultimate outcome of cancer therapy in individual patients is not easily predicted using currently available diagnostic techniques. As a result patients are often exposed to unsuccessful therapy which may cause dangerous side effects. Previous stu

A new technique for rapid multiple-frame chemical shift imaging and localized spectroscopy is reported. Unlike phase-encoding techniques and multiple-delay chemical shift imaging techniques, this technique permits spectroscopic imaging at high spatia

An NMR method which makes use of a radiofrequency (RF) field gradient to detect diffusion, perfusion, or flow is demonstrated. The technique is analogous to the detection of motion using pulsed B0 gradients. The simplest form of the experiment is as
