Abstract:
In a retrospective study, 198 contrast venographies were evaluated by two blinded observers for quality of opacification of the venous system and quality of documentation. There was good correlation between the two observers in 91% of the cases. They found an adequate contrast quality in 183 cases (92.4%), while in 15 cases (7.6%) incomplete contrast was found in some parts of the calf or pelvic veins. Most venograms (195, or 98.5%) were adequately documented. In conclusion, contrast venography is an excellent method for evaluation of the venous system, if performed adequately. Nevertheless, there is room for improvement of both technique and documentation.
