Unenhanced 3D Ghost MR Angiography by Toggled Systolic and Diastolic Imaging

Ioannis Koktzoglou¹, Robert R. Edelman¹

Ghost magnetic resonance angiography (MRA) is a new method for unenhanced and enhanced angiography that is predicated on ghost artifacts and does not use signal subtraction. We show that 3D unenhanced Ghost MRA can be performed by triggering the acquisition of every other slice-encoding step to systole and the remaining steps to diastole. When applied to the peripheral arteries, the 3D Ghost MRA method was found to perform better than a conventional subtraction-based unenhanced MRA method.
