Imaging modalities represented on the cover
Top left: Diffusion tensor imaging (DTI). Supertoroidal DTI can detect the difference between tumor tissue and surrounding oedema, as shown here in the brain. This image, by the Martinos Center’s Choukri Mekkaoui, depicts the integration of
supertoroidal DTI and tractography imaging.
Top right: Simultaneous positron emission tomography (PET)-magnetic resonance imaging (MRI). The Martinos Center’s
Joshua Roffman created this image to accompany a study of how the interactions between key neural networks change during working memory.
Bottom left: Structural magnetic resonance imaging. This image was acquired using the new “GOBrain” protocol, which
Center investigators developed in partnership with Siemens Healthcare to reduce the length of a standard clinical brain
exam to under five minutes.
Bottom right: Optical coherence tomography (OCT). This image, by the Martinos Center’s Caroline Magnain, shows the
medial temporal lobe of the brain (hippocampal formation) with a resolution of a few micrometers.
