Single echo techniques to acquire both angiography and venography information using susceptibility weighted imaging (SWI) usually require trade offs between the angiography and venography in the choice of echo time and flip angle. This work examines the role of bandwidth and resolution in reducing flow losses in the angiography while maintaining a long echo time for the venography. Two downsampling filters used to improve the quality of the venography are also examined.
