High-dose dobutamine stress SSFP cine MRI at 3 Tesla with patient adaptive local RF shimming using dual-source RF transmission
نویسندگان
چکیده
Background Image quality of cine imaging using steady state free precession (SSFP) sequences at 3T is insufficient due to increased RF-inhomogeneity (B1 field) and the high sensitivity of SSFP sequences to off-resonance artefacts. Recently, the introduction of a dual source RF transmission system with patient-adaptive local RF-shimming has led to a significant improvement of image quality of SSFP imaging at 3T. The objective of this study was to prospectively evaluate the feasibility, image quality and diagnostic accuracy of high-dose dobutamine stress magnetic resonance imaging (DSMR) at 3T comparing dual-source versus single-source transmit technology.

Introduction: The clinical implementation of high field MRI systems has introduced new challenges for body imaging with respect to B1 field nonuniformities, which can result in the generation of standing waves and signal loss particularly in abdominal imaging. Several approaches have been proposed to achieve a more homogeneous excitation and to avoid a degradation of image quality at higher mag...

Background Dobutamine stress magnetic resonance (DSMR-wall motion) has been established as a valuable tool for the detection of inducible wall motion abnormalities. Additional perfusion imaging during DSMR (DSMR-perfusion) was shown to improve sensitivity for the detection of myocardial ischemia. Current experience is based on 1.5T only, mainly due to insufficient image quality of steady state ...
