Semiquantitative analysis of first pass perfusion may contribute additional information to tumor characterization. The aim of the study therefore was to determine, whether dynamic contrast material-enhanced magnetic resonance (MR) imaging with use of kinetic parameters reveals statistically significant differences between benign and malignant cardiac tumors. The calculated contrast enhancement ratios (CER %), the maximum slope of the contrast enhancement ratio curve (% / sec) and the area under the contrast enhancement ratio curve (% * sec) resulted in significantly higher values for malignant cardiac lesions in comparison to benign lesions.
