Time-resolved multiphasic MR angiography (TRMRA) has been suggested as a
useful tool for assessment of anatomical and hemodynamic information of
vascular structure. Although TRMRA with contrast agent injection gives huge
amount of 4D data, most previous reports have been relied on visual inspection
of time series of projection images. Hence, proper processing of acquired 4D
data is required to enhance clinical utility of TRMRA. At this point, we propose
an automatic extraction algorithm for arterial input function and venous output
function in the neck region from 4D TRMRA data.
