(A)STIR :抑制脂肪(B)FLAIR :抑制水(C)Magnetization transfer technique :Magnetization transfer techniques are equally effective for both non-contrast and contast-enhanced MRA. Because gadolinium (Gd) enhancement is caused by a water-Gd ion interaction (not macromolecular cross-relaxation), MT pulses suppress the signal from background tissues and render Gd-enhanced areas more conspicuous.Time of flight MRA without (left) and with (right) MT suppression. Note better visualization of small vessels after MT pulse.出處:http://mriquestions.com/magnetization-transfer.html(D)FLASH :Fast low a...
