Journal ArticleDOI
Magnetic Resonance Imaging of Blood Flow with a Phase Subtraction Technique: In Vitro and In Vivo Validation
Avery J. Evans,Fumiharu Iwai,Thomas A. Grist,Henry Dirk Sostman,Laurence W. Hedlund,Charles E. Spritzer,Rosa Negro-Vilar,Craig A. Beam,Norbert J. Pelc +8 more
TL;DR: Velocity-encoding phase subtraction MRI bears potential clinical use for the evaluation of blood flow and potential applications would be in the determination of arterial blood flow to parenchymal organs, the detection and quantification of intra- and extra-cardiac shunts, and the rapid determination of cardiac output and stroke volume.
Journal ArticleDOI
Evaluation of BA1112 rhabdomyosarcoma oxygenation with microelectrodes, optical spectrophotometry, radiosensitivity, and magnetic resonance spectroscopy.
H. Dirk Sostman,Sara Rockwell,A. L. Sylvia,David Madwed,Gary P. Cofer,H. Cecil Charles,Rosa Negro-Vilar,Deborah Moore +7 more
TL;DR: The results indicate that tissue oxygenation can be manipulated reproducibly in the BA1112 rhabdomyosarcoma and suggest that 31 P MRS can be used to monitor changes in tumor oxygenation in this model system.
Journal ArticleDOI
MR characterization of blood flow in native and grafted internal mammary arteries.
Jörg F. Debatin,John A. Strong,Henry Dirk Sostman,Rosa Negro-Vilar,S S Paine,James Douglas,Norbert J. Pelc +6 more
TL;DR: The feasibility of using cine phase‐contrast MR imaging as a quantitative method of evaluating blood flow in IMA coronary artery bypass grafts is shown.
Journal ArticleDOI
Detection, characterization and functional assessment of reperfused Q-wave acute myocardial infarction by cine magnetic resonance imaging
TL;DR: Findings suggest that cine MRI may play an important role in the future detection and functional characterization of AMI.
Journal ArticleDOI
Heterogeneous signal intensity in magnetic resonance images of hypertrophied left ventricular myocardium

TL;DR: Hypertrophied myocardium shows reproducible differences from normal tissue with magnetic resonance imaging; hence, quantitative magnetic resonance tissue characterization may be useful in assessing pathologic changes in LVH.
