The object of this study is to compare four different dosages of Gadavist 1.0 in cardiac
Magnetic Resonance Tomography (MRT) imaging with the imaging results of a cardiac SPECT
examination in terms of diagnostic quality.
For this purpose Gadavist dosages of 0.01 mmol/kg, 0.025 mmol/kg, 0.05 mmol/kg or 0.1mmol/kg
body weight are administered. A study participant receives the respective dose twice i.e. at
rest and at stress using Adenosine (which puts circulation into a state of stress similar to
that of physical exercise). The time between both injections is 10-15 min.
The total imaging time is about 45 min.
