Abstract:
The choice of sequence, scanning delay time, dosage and flow rate of contrast medium, patient's cooperation, and post processing of the images were discussed in this article. Fast, multiphase scanning, and fat saturation were required for the best sequence of contrast-enhanced MRI angiography. The delay time should be determined by bolus test injection, 30 ml contrast medium at 2-3 ml/s flow rate were recommended, good cooperation from the patients and felicitously post processing of the images were also necessary for successful examination.
