Abstract: Since MR angiography (MR) can demonstrate the whole brain arterial system without introduction of contrast medium, it is very useful in screening for aneurysm, AVM and vascular occlusion in outpatients.
There are two methods in MRA-subtraction and non-subtraction methods (time of flight, TOF).
The magnetization transfer contrast (MTC) technique can demonstrate smaller vessels and slower blood flow than any conventional TOF-MRA.
Compared with the subtraction MRA, the MTC-TOF-MRA demonstrates smaller vessels clearly in a shorter time. By Gd-enhancement, the image of the arterial system can be also improved on the MTC method.
