The most established functional MR imaging technique for activation studies relies on a T2*-weighted contrast. This signal arises primarily from a blood oxygen level dependent contrast generated by an imbalance between the increase in regional cerebr

NMR spectroscopy: current status and future possibilities

Autor: Dg, Gadian, Sr, Williams, Timothy Bates, Ra, Kauppinen

Publikováno v: Europe PubMed Central

Nuclear magnetic resonance (NMR) spectroscopy is now established as a non-invasive method of studying metabolism in living systems, ranging from cellular suspensions to man. With respect to clinical applications, recent developments include the succe

1. The activity of creatine kinase in intact anaerobic frog muscle at 4 degrees C at rest and during contraction was investigated by using saturation-transfer 31P n.m.r. 2. At rest, the measured forward (phosphocreatine to ATP) reaction flux was 1.7

Publikováno v: Neuroradiology. 30(5)

Results of MRI at 0.15T in twelve successive patients with intracerebral haematoma are reviewed. Using T2 weighted spin echo (SE) and partial saturation (PS without a refocussing 180 degree pulse) sequences, low intensity areas were seen in eleven of
