- W23573058 abstract "Magnetic resonance imaging (MRI) of the coronary arteries is a difficult subject. Owing to the motion of the heart during contraction and respiration artefact free imaging needs extremely fast techniques that MRI does not fully qualify yet. However, constant progress is made (1) and with electrocardiography triggering and respiratory motion correction techniques, submilliter resolution can be achieved with reasonable acquisition times (2). Only one study focussed on the use of magnetic resonance (MR) coronary angiography techniques for the detection of restenosis after coronary angioplasty (3). In this study, in which 118 patients after percutaneous transluminal coronary angioplasty were investigated, sensitivity for restenosis detection was 73% (11/15) and specificity was 49%. Overall accuracy was 53% for MRI, which was significantly (p = 0.014) lower compared with electron beam computed tomography. Unfortunately, MR coronary angiography of restenosis is currently hindered by the obligatory use of coronary artery stents to decrease the incidence of restenosis. Still MRI for the detection of restenosis is being performed using different alternative techniques and this subject will be reviewed in this chapter.KeywordsCoronary Flow ReserveMagn Reson ImagePercutaneous Coronary IntervenCoronary Flow Velocity ReserveElectron Beam Compute TomographyThese keywords were added by machine and not by the authors.
