1 Erratum to: Appl Magn Reson DOI 10.1007/s00723-017-0872-2

In the original publication of the article, Eqs. (3) and (4) are incorrect. The correct versions of these equations are given below. This has been corrected in the original version of the article.

$$\Delta M_{{z,{\text{res}}}} = -M_{z}^{0}\frac{\gamma^{2} B_{1}^{2} T_{1} T_{2} }{1+\gamma^{2} B_{1}^{2} T_{1} T_{2} } .$$
(3)
$$\Delta F_{{z,{\text{res}}}} = \frac{{{\text{d}}B_{z} }}{{{\text{d}}z}} \cdot \Delta M_{{z,{\text{res}}}} .$$
(4)
