Abstract
Pulsation artifact on gradient echo images with ultrashort TE (i.e., <3 msec) and intermediate TR is primarily from view‐to‐view amplitude modulation. Paramagnetic contrast agents increase the signal from blood during diastole without increasing the intensity of unsaturated systolic blood, decreasing signal modulation between systole and diastole. In a phantom and in humans, artifact decreased or remained the same following contrast enhancement.
