[The value of Doppler ultrasonography in gastroenterology: limitations and possibilities in the assessment of portal venous hypertension and in tumor diagnosis].
Due to technical progress, duplex sonography is growing in diagnostic value in gastrointestinal imaging. Color and pulsed spectral Doppler are the methods of choice in making information on morphologic and physiologic aspects of blood flow available. Amongst the various gastroenterologic applications, two important features are presented and discussed: investigation of the mesenterico-spleno-portal axis in patients with portal venous hypertension, and contributions to evaluation of primary and secondary liver tumors.
