spin echo — n a signal that is detected in a nuclear magnetic resonance spectrometer, that is an echo like replication of a free induction decay produced by a planned series of radio frequency pulses, and that can be used to extract more information from a… … Medical dictionary
Spin echo — In nuclear magnetic resonance, spin echo refers to the refocusing of precessing nuclear spin magnetisation by a 180° pulse of resonant radiofrequency.The NMR signal observed following an initial excitation pulse (orange in diagram) decays with… … Wikipedia
Spin-spin relaxation time — Spin spin relaxation time, known as T2, is a time constant in Nuclear Magnetic Resonance and Magnetic Resonance Imaging. It is named in contrast to T1, the spin lattice relaxation time.T2 characterizes the rate at which the Mxy component of the… … Wikipedia
Spin-lattice relaxation time — Spin lattice relaxation time, known as T1, is a time constant in Nuclear Magnetic Resonance and Magnetic Resonance Imaging. It is named in contrast to T2, the spin spin relaxation time.T1 characterizes the rate at which the longitudinal Mz… … Wikipedia
echo — 1. A reverberating sound sometimes heard during auscultation of the chest. 2. In ultrasonography, the acoustic signal received from scattering or reflecting structures or the corresponding pattern of light on a CRT or ultrasonogram. 3. In… … Medical dictionary

Steady-state free precession imaging — Steady state free precession (SSFP) imaging is a magnetic resonance imaging (MRI) technique which uses steady states of magnetizations. In general, SSFP MRI sequences are based on a (low flip angle) gradient echo MRI sequence with a short… … Wikipedia
gradient echo — n a signal that is detected in a nuclear magnetic resonance spectrometer that is analogous to a spin echo but is produced by varying the external magnetic field following application of a single radio frequency pulse rather than by application of … Medical dictionary
Functional magnetic resonance imaging — Functional MRI or functional Magnetic Resonance Imaging (fMRI) is a type of specialized MRI scan. It measures the haemodynamic response related to neural activity in the brain or spinal cord of humans or other animals. It is one of the most… … Wikipedia
