title: In vivo detection of experimentally induced cortical dysgenesis in the adult rat neocortex using optical coherence tomography.
abstract: Imaging cerebral structure in vivo can be accomplished by many methods, including MRI, ultrasound, and computed tomography. Each offers advantages and disadvantages with respect to the others, but all are limited in spatial resolution to millimeter-scale features when used in routine applications. Optical coherence tomography (OCT) is a new, high resolution imaging technique which uses light to directly image living tissue. Here, we investigate the potential use of OCT for structural imaging of the fully developed mammalian cerebral cortex. In particular, we show that OCT can perform in vivo detection of neocortex and differentiate normal and abnormal cortical anatomy. We present the results of detailed optical coherence tomographic (OCT) observations of both normal and abnormal rat neocortex obtained in vivo. Comparative histologic analysis shows excellent correlation with the OCT tomograms.
