Dynamic contrast-enhanced MRI is an important tool for detection and characterization of breast lesions. With the availability of high field systems for clinical routine (3T) and research (7T) increased SNR and spatial resolution may improve diagnostic accuracy for breast MRI. To test the feasibility of breast MRI at 3T and 7T specificity, sensitivity and SNR were calculated in 24 patients. In addition B1-maps were measured at 3T and 7T in five healthy subjects.
