Improvement of fat suppression is important for whole heart coronary magnetic resonance angiography (WHC-MRA), because Unwanted signal arising from fat can compromise vessel delineation and decrease the diagnostic value of WHC-MRA. Balanced DIXON (bDIXON) can reduce fat suppression unevenness than SPIR method while maintaining high signal value. However, it is yet not applied for WHC-MRA. Furthermore, 3D non-selective bDIXON (3D NSbDIXON) with shortening TR can suppress an increase in imaging time. We propose a new sequence of 3D NSbDIXON for WHC-MRA, and examine the image quality in comparison to the conventional methods.
