Role of diffusion weighted MRI sequence in evaluation of cholangiocarcinoma

ABSTRACT

Background: cholangiocarcinoma requires accurate diagnosis, which relies on appropriate imaging and image-guided biopsy. Diffusion weighted MRI is a relative new and increasingly used technique. It can be obtained during a single breath-hold, there is no need to use contrast media and it provides information that reflects tissue cellularity and organization. ADC maps can provide quantitative measurements of tissue water diffusivity. It proved to be helpful in the characterization of cholangiocarcinoma
