Journal ArticleDOI
Impact of Vasodilation on Oxygen-Enhanced Functional Lung MRI at 0.55 T.
Björn Wieslander,Felicia Seemann,Ahsan Javed,Christopher G Bruce,Rajiv Ramasawmy,Andrea E. Jaimes,Katherine Lucas,Victoria Frasier,Kendall J. O’Brien,Amanda Potersnak,Jaffar M. Khan,William H. Schenke,Marcus Y Chen,Robert J. Lederman,Adrienne E. Campbell-Washburn +14 more
TL;DR: In this article , the relative contribution of the T1-shortening and vasodilatory effects of oxygen to signal enhancement in OE-MRI in both swine and healthy volunteers was quantified.
Journal ArticleDOI
An interleaved-navigator projection dual-echo bSSFP sequence for respiratory self-gated imaging
TL;DR: This work proposes a dual-echo balanced SSFPbased imaging sequence that acquires a constant navigator projection during every TR and alternatesnavator projection direction for robust motion measurement.
Journal ArticleDOI
BATMAN—Savior or vigilante?
TL;DR: Percutaneous laceration of the anterior mitral leaflet, pre‐emptive alcohol septal ablation, and transatrial leaflet resection are alternative strategies that prevent LVOT obstruction from TMVR.
Journal ArticleDOI
Spiral imaging with off-resonance reconstruction for MRI-guided cardiovascular catheterizations using commercial off-the-shelf nitinol guidewires
Adrienne E. Campbell-Washburn,Toby Rogers,Kanishka Ratnayaka,Kanishka Ratnayaka,Burcu Basar,Ozgur Kocaturk,Ozgur Kocaturk,Hui Xue,Robert J. Lederman,Michael S. Hansen,Anthony Z. Faranesh +10 more
TL;DR: RF-efficient spiral imaging is used for MR-guided cardiovascular catheterization, with real-time off-resonance reconstruction for improved visualization of off-the-shelf nitinol guidewires.
Journal ArticleDOI
LAMPOON transseptal mitral valve in ring.
Norihiko Kamioka,Jaffar M. Khan,Robert J. Lederman,Peter C. Block,Vasilis Babaliaros,Adam Greenbaum +5 more
TL;DR: Transcatheter mitral valve-in-ring or valve- in-mitral annular calcification are more challenging compared to transcatheter mitigation therapy because of a shorter and non-circular landing zone and difficulty in achieving optimal coaxiality.
