Dose response of the intravascular contrast agent gadofosveset trisodium in MR perfusion imaging of the myocardium using a quantitative evaluation
This study was performed to determine the best concentration of gadofosveset at 1.5 and 3 T MRI for quantitative myocardial perfusion analysis. 18 healthy volunteers have been examined at a 1.5 and a 3 T MRI s...

Thorax and Vasculature
While MRI is an imaging method of first choice in almost all parts of the human body its acceptance for thoracic imaging is rather low even today. One of the reasons is of course that CT has developed dramatic...

Myocardial tagging with steady state free precession techniques and semi-automatic postprocessing—impact on diagnostic value
Our aim was to determine the diagnostic value of myocardial tagging sequences with regard to the evaluable share of the cardiac cycle. Thirty-three patients were examined at 1.5 T using tagging sequences with ...

Code blue in the MR suite – a drill to rescue a patients with cardiac arrest from the MR scanner
Dobutamine stress MR (DSMR) is increasingly used in the clinical routine. Due to the limitations inherent to MR, i.e. the distance of the personnel to the patient during imaging, it is necessary to set up an e...
