Magnetic resonance water imaging

Magnetic resonance water imaging uses the long T2 characteristic of water. The T2 value of static or slow flowing fluid in the body is much larger than other tissues. The T2 sequence with a heavy T2 weight (select a long TE) is used, and the lateral magnetization of other tissues The vector is almost completely attenuated, the signal strength is very low, and there is almost no signal, while the water still maintains a large transverse magnetization vector, which makes the water-containing organ develop.
