Breast MRI at Highfield

Puropose: Breast MR imaging has an established role for staging primary cancer and for diagnosing recurrent tumor. Recently, it has also been suggested as screening tool in specific high risk cohorts. In particular in a screening setting, a high PPV is mandatory. One way to improve the technique's PPV is by improving morphologic analysis of enhancing lesions by higher matrix imgaing. MR systems operating at stronger magnetic fields (e.g. 3.0T) may offer the higher SNR that is necessary for high-matrix time-resolved MR imaging. On the other hand, high field systems may go along with specific difficulties that are…
