NiTi stents exhibit superior MRI compatibility and allow direct MR imaging through the stented area. In the present study, pulsatile in-vitro flow measurements were obtained by Magnetic Resonance Phase-Velocity mapping (MR-PVW) through a nickel-titanium alloy stent with different grades of stenosis: a) 75%, 90% (symmetric) and 50% (asymmetric). The results showed clear visibility of the lumen through the stent/stenosis when compared with independent calculations of flow. The detection and evaluation of instent restenosis using these techniques could provide a non-invasive means of screening for further management of patients. | URI: | https://hdl.handle.net/20.500.14279/2447 | ISSN: | 10716947 | Rights: | © ASME | Type: | Conference Papers | Affiliation: | University of Alabama at Birmingham |
