Magnetic resonance imaging (MRI) is a new and potentially very useful imaging modality in equine orthopaedics. In MRI, the part of the limb being imaged is placed within a strong magnetic field and subjected to perturbing radiofrequency (RF), pulses.

An electrocardiogram (ECG) monitoring system has been developed and evaluated in normal volunteers (n = 7) and patients with various cardiac diseases (n = 24) in a 1.9 tesla magnet during magnetic resonance spectroscopy studies. To minimize an ECG si

Phosphomonoesters (PME-mainly phosphoethanolamine), and phosphodiester + phospholipid bilayers (PDE + PB) can be quantified noninvasively using phosphorus MRS. Spectra from the livers of 7 normal infants (gest'n 27-40w, age 3-76d), and the brains of

Progressive cerebral ischemia was induced in seven anesthetized hyperglycemic rats by carotid artery ligation and hemorrhagic hypotension. Phosphorus metabolites, intracellular pH, and lactate in the brain were monitored by 31P and 1H magnetic resona

31P MRS was used to investigate disruption of brain energy status by a combination of hyperbilirubinaemia and an open blood-brain barrier (BBB). Spectra were acquired using a surface coil over the right cerebral hemisphere of anaesthetised adult male

Two full-term neonates with focal seizures were studied by spatially-localised phosphorus magnetic resonance spectroscopy (MRS). Both had unilateral cortical lesions on computerised tomography, and have subsequently developed infantile spasms. Electr
