In this study, the combination of MRE and ce MRI could increase the diagnostic performance of breast MRI. Further investigations of larger cohorts and smaller lesions (in particular those only visible on MRI) are necessary to validate these results.

Background: Extra-adrenal myelolipomas are rare benign tumours. Other soft tissue tumours such as well-differentiated liposarcomas appear morphological almost identical. Preoperative imaging and especially biopsy are important tools to diagnose these lesions.

A theoretical analysis of a ring electrode in turbulent pipe flow is given in order to estimate the limits of resolution of a given experimental setup. Special attention is paid to error analysis, which is necessary for the correct evaluation of the data. To demonstrate the potentialities of this method for kinetic studies, the apparent exchange current density of the ferroferricyanide system was measured. The values obtained are higher than those reported in the literature.
