Diastolic pseudogating

Last revised by Tom Foster on 27 Jul 2022

Diastolic pseudogating appears as periodic bright and dark signal in arteries such as the aorta as one progresses through a series of images. Synchronisation of the cardiac cycle and the pulse sequence results in high signal in the artery during diastole when blood is relatively stationary and loss of signal during systole when the flow is high.

The change in intensity of blood occurs when there is synchronisation of the cardiac cycle and the pulse sequence, i.e., repetition rate = heart rate or TR=1/HR.
