Title: Magnetic resonance angiography apparatus
Inventor: MACHIDA YOSHIO
IPC: G01R33/48
Filed: 1990-10-03
Abstract: PURPOSE:To obtain a subtraction image with a high contrast by making an echo time in a dephasing sequence longer than the echo time in the rephasing sequence. CONSTITUTION:When a rephasing sequence is executed, an electrostatic magnetic field is applied to an object P to be inspected statically from an electrostatic magnetic field magnet 1 as driven with an electrostatic magnetic field controller 4. Then, when a dephasing sequence is executed, a nuclear magnetization of a nuclear spinning is dephased with the application of an inclined magnetic field Gr for reading while an inclined magnetic field Ge for encoding is applied to perform a phase encoding. Here, an echo time TEd of the dephasing sequence is made longer than the echo time TEr of the rephasing sequence. If so, a larger phase shift value is possible with a longer applying time of an inclined magnetic field for flow encoding and this enables the obtaining of an image with a high contrast at a moving part with a higher dephasing effect.
