Dynamic four-dimensional MR angiography of the chest and abdomen.


Time-resolved (four-dimensional) contrast-enhanced MR angiography (CE-MRA) circumvents many of the adverse effects and limitations of conventional x-ray digital subtraction angiography. Four-dimensional CE-MRA uses improvements in gradient hardware, pulse sequences, or computational power to reduce scan times to seconds or less, allowing rapid sequential… (More)
