ABSTRACT:
A 3DFT MRA dynamic study is performed using a contrast agent to enhance image contrast. A monitor pulse sequence is performed at a high temporal rate to monitor the magnitude of the NMR signal produced in a monitor region after the contrast agent is injected into the patient. When the monitor signal reaches a threshold value, the patient is signaled and the 3DFT image data set is acquired.
