Abstract

Histology, including immunohistochemistry, and magnetic resonance imaging microscopy (μMRI) are complementary techniques for the analysis of brain structure. Therefore, μMRI analysis, often of formalin-fixed tissue, precedes histologic evaluation of the same experimental animal in many studies. However, the application of gadopentetate dimeglumine (Gd-DTPA), while of value for MRI studies, has an unknown effect on subsequent histology. We demonstrate here that for the mouse brain, histology with Nissl staining and immunostaining for microtubule-associated protein 2, using standard techniques for tissue preparation, are unaffected by prior perfusion of the tissue with Gd-DTPA. This conclusion was based on qualitative morphologic comparisons of stained sections, as well as quantification of mean immunofluorescence pixel intensities from Gd-treated (mean±S.D.=131.2±28.4; n=3) as compared to nontreated specimens (116.2±34.7; n=3, P=.7). Therefore, Gd-DTPA may be applied as a μMRI contrast agent in formalin-fixed brain tissue prior to histologic studies.
