Date Entered 4/28/98, acronym, motsa, expansion, multiple Overlapping Thin Slab Angiography, explanation (Diagram). The value of dB/dt is measured in Tesla per second (T/s). Phase - an angular relationship describing the degree of synchronism between two sinusoidal waveforms of the same frequency. If the gradient applied with the refocusing RF pulse has a reversed polarity compared to the gradient applied with the excitation RF pulse, any through-plane chemical shift of fat signal will occur in the opposite direction. An in-plane saturation pulse suppresses background tissue signal, and a tracking saturation pulse to suppress venous signal prior to a quiescent inflow period.

The width of the excited volume is thus restricted to the encoded volume of interest, excluding the arms EPI Echo Planar Imaging Rapid changes of frequency-encoding gradient polarity to refocus the MR echo many times after a single RF spin excitation, with a small change. Multiple acquisitions are acquired with different frequency offsets, and the resultant range of off-resonance images are summed at each slice location. TOF techniques utilize flow-related enhancement whereas PC techniques utilize phase accumulation along a gradient. Inhomogeneity induced geometrical shifts and hence the intensity changes are corrected, since the addition of the compensation which is independent from the field inhomogeneities, including both chemical shifts and susceptibility VCG Variable Coil Geometry VCG VectorCardioGram VEF Volume ejection fraction venc Velocity ENCoding verse VariablE-Rate. As each signal component has experienced a different phase encoding gradient pulse, its exact spatial reconstruction can be specifically and precisely located by the Fourier transformation analysis. Saturation recovery - a little-used pulse sequence that generates a predominately proton density dependent signal, basically employing a 90 RF excitation pulse, with a very long repetition time. Scan time is reduced, resolution is maintained, SNR is reduced. See FC flair FLuid Attenuated Inversion Recovery Inversion recovery (IR) with a long inversion time (TI at the sonera easy puheaika viihdelinjat null point of fluid (no signal from fluid). 2D spatially-selective echo-panar (in excitation k-space) RF excitation pulse reduces the excitation volume in both the phase encoding and slice select directions FOS Fold-over Suppression Prevention of aliasing from tissue outside of the FOV wrapping into the image. In spin-echo imaging, each echo is formed by a 180É pulse. Reconstruction - the mathematical process by which the displayed image is produced from the raw k-space data obtained from the receiver circuitry, typically utilizing Fourier transformation and selective filtering. First, a 45 excitation pulse flips both fat and water. Additional requirements include TR T2, and RF excitation pulses must be phase coherent (or sign-alternated). Algorithm involves selecting largest value (maximum intensity) along a set of imaginary viewing angles through the imaging volume. After RF excitation, this vector returns to its equilibrium value at a rate characterized by the time constant. There is no requirement for additional electrical power or cooling, and the iron-core structure of the magnet leads to a limited fringe field and no missile effect. Phase encoding - the process of locating an MR signal by altering the phase of spins in one dimension with a pulsed magnetic field gradient along that dimension prior to the acquisition of the signal. 0.5 NEX nibp Non-Invasive Blood Pressure NMR Nuclear Magnetic Resonance The precession of the net magnetisation vector when it is out of alignment with the external magnetic field.
