Dynamic contrast enhanced imaging (DCE-MRI) is an important tool to detect breast lesions high sensitivity and specificity. In this pilot study we compared DCE-MRI in seven patients with invasive ductal carcinomas at 3 and 7 T. This resulted in bilateral T1w-images with high spatial resolution and good image quality in all patients at both field strengths. The increase in the contrast-to-noise ratio was in average 2.375 times higher at 7T compared to 3T. In addition, the specificity at 7 T was increased. This study suggests that DCE-MRI is possible at 7 Tesla and may further increase diagnostic accuracy in clinical MR imaging of the breast.
