SPACE sequence has recently been used to obtain high resolution 3D images at 3.0T MRI. This has the advantage that it reduces SAR by use of the variable flip angle. The other great advantage of SPACE is the shortening of echo spacing. However, this has not previously been focused on. This prospective study using 20 healthy volunteers quantitatively verified the superiority of SPACE MRCP to conventional 3D TSE MRCP at 1.5T MRI due to the shortening of echo spacing.
