Contrast Enhanced Magnetic Resonance Angiography with Gadofosveset Used in Detection and Localization of Bleeding
نویسندگان
چکیده
It has been established that internal hemorrhage can be detected and localized with noninvasive and minimally invasive imaging methods such as CT angiography, conventional angiography and nuclear scintigraphy. The use of steady-state MRI with the relatively new intravascular contrast agent gadofosveset offers the possibility of accurate anatomic localization of bleeding without the use of ionizing radiation or iodinated contrast media. To illustrate this assertion, we describe two cases from our institution in which MR angiography was successfully performed specifically for this indication.

Gadofosveset-enhanced magnetic resonance angiography
Gadofosveset (Vasovist, Bayer Schering Pharma AG, Berlin/Germany) is the first intravascular contrast agent approved for use with magnetic resonance angiography in the European Union, Switzerland, Turkey, Canada, and Australia. Gadofosveset reversibly binds to albumin providing extended intravascular enhancement compared wth existing extracellular magnetic resonance contrast agents. Prior to ap...

The purpose of this study was to prospectively evaluate the diagnostic accuracy of reader detection of 75% or greater stenosis at high-spatial-resolution multistation magnetic resonance (MR) angiography performed with matrix coils and a blood pool contrast agent. Ten healthy volunteers and 10 patients were examined. All participants provided informed consent to participate in this institutional...

Stroke, a major cause of death and disability in the developed world, is usually caused by atherosclerosis, most commonly an arterioocclusive lesion at the carotid bifurcation. Numerous multicentre trials have demonstrated that carotid endarterectomy can reduce the risk of stroke in these patients. However, because of the morbidity of catheter angiography coupled with the risks of surgery, the ...
متن کاملGadofosveset trisodium in coronary magnetic resonance angiography at 3 Tesla
Background Coronary magnetic resonance angiography (MRA) at 3T suffers from imaging inconsistencies compared to 1.5T despite the use of gadolinium-based contrast agents (GBCAs). Gadofosveset Trisodium (Ablavar, Lantheus Medical Imaging), with its high relaxivity and long intravascular residence time, offers greater potential over standard GBCAs to improve evaluation of the coronary arteries.
