Three dimensional and Doppler ultrasound examination before and after procedures of the biliary system

Aim of the study: Digital technique has a new era in three-dimensional ultrasound/3DUS/diagnostics, which makes possible the immediate spatial reconstruction of the opened investigated area. It is applicable in the evaluation of circulation by means of color- and power-Doppler method. In case of interventional procedures we used the three orthogonal-plane and 3D reconstruction method. We searched for pathologic biliary obstruction and signs of dislocation and compression by color-Doppler examination. Patients and methods: 12 patients with benign and malign biliary obstruction (before and after retrograde cholang…
