[Trends in the nuclear-medical diagnosis of thrombosis].

Use of the 125I-fibrinogen-uptake test for detection of freshly developing thrombi is well known. The administration of radiofibrinogen to detect preformed thrombus - the retrospective variant of the 125I-fibrinogen-uptake test - allows the diagnosis of established thrombosis. The correlation with ascending phlebography is 90%. 125I-Fibrinogen cannot be used for scanning, due to its low energy, while 131I-fibrinogen if used involves a high radiation dose to the patient. First experiments with new radiopharmaceuticals for detection of deep vein thrombosis are proposed. Indication lists for the retrospective variant of the 125I-fibrinogen-uptake test are given.
