title: Some aspects of phlebographic technique.
abstract: When contrast medium is infected into an artery it flows to0wards the branches distally to the injectionsite. If, however, the contrast medium is injected into a vein the flow of the contrast medium usually has several routes to strive toward the right atrium. The flow in the veins may be affected by using e.g. compression, Valsalva manouore or gravity. By taking these aspects in the technique into consideration the diagnostic value of the phlebography can in many cases be improved.
