What’s Inside the Magnet and Why?chosen direction and is measured in units of milliTesla per meter (mT/m). A radiofrequency (RF) magnetic field that oscillates at a characteristic frequency in the MegaHertz range, the exact value of which is determined by the nominal field strength of the main magnet. This is given the symbol B..

Pulse Sequences and Image Contrasthe . The two main types of pulse sequences are . and spin . pulse sequences. The choice of pulse sequence and its imaging parameters, including the timing parameters. and ., determine the intrinsic strength of the MR signal from a particular tissue according to its proton density value and relaxation properties.

Black Blood Versus Bright Blood Imaging, this results in a signal void, also known as a “.” or “. appearance. This effect is also known as the ., referring to the “washout” of proton spins form the image slice that would otherwise be refocused and contribute to the spin echo signal.

Protons and Spins: The Origin of the MRI Signalcontained within . and . (Fig.3.1). Hydrogen is one of a number of elements whose nuclei exhibit magnetic resonance properties, but the high intrinsic sensitivity and natural abundance in the form of water and lipid molecules makes it particularly favorable for imaging. Other nuclei of potential int
