Automatic respiratory gating for contrast ultrasound evaluation of liver lesions
Christofides, Damianos; Leen, Edward; Averkiou, Michalakis A. (2014)Dynamic contrast-enhanced ultrasound (DCEUS) has been used in radiology for many years for lesion detection and characterization. In recent years, more emphasis has been placed on tumor perfusion quantification with DCEUS. ...

Automatic respiratory gating for perfusion quantification of DCEUS
Christofides, Damianos; AVERKIOU, MICHALAKIS A.; Leen, Edward (2013)A novel automatic respiratory gating (ARG) algorithm for ultrasound is presented. The ARG algorithm was applied on dual contrast imaging (contrast/tissue) loops in order to remove respiratory motion artifacts from dynamic ...

Evaluation of the Accuracy of Liver Lesion DCEUS Quantification With Respiratory Gating
Christofides, Damianos; Leen, Edward; AVERKIOU, MICHALAKIS A. (2016)Confidence in the accuracy of dynamic contrast enhanced ultrasound (DCEUS) quantification parameters is imperative for the correct diagnosis of liver lesion perfusion characteristics. An important source of uncertainty in ...

Improvement of the accuracy of liver lesion DCEUS quantification with the use of automatic respiratory gating
Christofides, Damianos; Leen, Edward; Averkiou, Michalakis A.; Leen, Edward L. S.; Averkiou, Michalakis A. (2016)Objectives: To evaluate the efficiency of automatic respiratory gating (ARG) in reducing respiratory motion-induced artefacts from dynamic contrast-enhanced ultrasound (DCEUS) acquisitions and to assess the impact of ARG ...
