syngo TWIST for dynamic time-resolved MR angiography

DOI:10.3969/j.issn.1674-8034.2012.05.015.


[Abstract] With the advantages of non-invasion, low false positive rate and so on, 3D dynamic contrast-enhanced MRA has been recognized as one MR technique with high diagnostic value and clinical significance. But for conventional contrast-enhanced MRA, it is hard to estimate the time of delayed scanning after contrast injection and eliminate the venous contamination. syngo TWIST technique launched by Siemens achieves significant improvements in temporal and spatial resolution by manipulating the k-space coverage and using in combination with parallel imaging. With syngo TWIST, there is no need to judge the time to peak after contrast injection. We can completely eliminate the venous contamination and use smaller amounts of contrast agent. In this paper, the underlying principles and initial clinical applications for syngo TWIST will be presented which shows the potential to be applied in the assessment of vascular disease..
