Venous MR imaging with blood pool agents
- 62 Downloads
Blood pool contrast agents such as Gadofosveset trisodium (Vasovist®, Bayer Schering Pharma AG, Berlin, Germany) are making MRA a viable first-line imaging modality for a variety of patients with venous disorders. They allow extended imaging and multiple acquisitions without loss of resolution with a single low-dose injection. The methodology is robust and can be adjusted to the patient without causing workflow problems. The emphasis of this article is on the venous applications of the blood pool contrast agent Vasovist® including venous visualisation to plan surgical and interventional procedures and venous thromboembolism, in the form of deep vein thrombosis (DVT) and pulmonary embolism (PE), where MRA with blood pool agents can help to avoid exposure to ionising radiation.
