Does radiotherapy prolong biliary metal stent patency in malignant pancreatobiliary obstructions?
The patency of biliary metal stents in pancreatobiliary cancer patients who receive chemoradiation therapy is significantly longer than that in patients who do not receive radiotherapy, which suggests that local cancer control significantly affects stent patency.
Orthogonal crushers are easy to implement and can be used for any variant of diffusion imaging sequences (e.g., diffusion tensor imaging, fiber diameter mapping) where the twice-refocused scheme is used.
