The self-describing data sets file protocol and Toolkit

Insufficient contrast filling, especially of the anterior tibial, common femoral and iliac veins, was the most common reason for disqualifying examinations. Unilateral examinations and obscuring metallic devices were the second and third most common reasons, respectively. Efforts should be made to standardize the phlebography technique, to use a large volume of contrast without tourniquets, and to obtain an appropriate number of views to visualize the deep veins.
