Novel imaging reagents and technology that non-invasively locates, quantifies specific cells in the body

Magnetic resonance imaging (MRI) isn't just for capturing detailed images of the body's anatomy. Thanks to novel imaging reagents and technology developed by Carnegie Mellon University scientist Eric Ahrens, MRI can be used to visualize - with "exquisite" specificity - cell populations of interest in the living body. The ability to non-invasively locate and track cells, such as immune cells, will greatly aid the study and treatment of cancer, inflammation, and autoimmune diseases, as well as provide a tool for advancing clinical translation of the emerging field of cellular regenerative medicine, by tracking stem cells for example.

Hodgkin's lymphoma treatment can cause late sequelae

Depending on the type of treatment given, however, there may be late sequelae, as discussed by Wolfgang Dörffel and colleagues in an original article in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2015; 112: 320-7).
