Magnetic resonance venography and liver transplant complications.
Abstract
Hepatic vein stenosis is a rare but serious complication following liver transplantation. Multiple modalities can be utilized to image the hepatic vasculature. Magnetic resonance venography (MRV) provides certain advantages over ultrasound, computed tomography angiography and digital subtraction venography. MRV utilizes the same imaging principles of magnetic resonance angiography in order to image the venous system. Blood pool contrast agents, specifically gadofosveset trisodium, allow for steady state imaging up to 1 h following injection, with improved visualisation of vital venous structures b...

Dose response of the intravascular contrast agent gadofosveset trisodium in MR perfusion imaging of the myocardium using semiquantitative evaluation
Conclusion:The best injection protocol for semiquantitative perfusion analysis at 1.5 T is 0.00375 mmol/kg, as higher doses lead to lower upslope values during the second perfusion. At 3 T 0.0075 mmol/kg should be used to avoid dark banding artifacts. J. Magn. Reson. Imaging 2013;. © 2013 Wiley Periodicals, Inc. (Source: Journal of Magnetic Resonance Imaging)

Evaluation of an albumin-binding gadolinium contrast agent in multiple sclerosis
Conclusion:
Gadofosveset trisodium after 4 hours significantly improves the number of detected contrast-enhanced multiple sclerosis lesions as compared to Gd-DOTA after 4 minutes, even though the injected dose of gadolinium was two-thirds lower. (Source: Neurology)

Re: Comprehensive MRA of the lower limbs including high-resolution extended-phase infra-inguinal imaging with gadobenate dimeglumine: Initial experience with inter-individual comparison to the blood-pool contrast agent gadofosveset trisodium
Sir — I was interested to read the above article comparing “newer” standard (gadobenate) versus blood-pool contrast agents (BPCA; gadofosveset) for lower-limb magnetic resonance angiography (MRA) in a somewhat small series of 20 patients. If MRA is indeed the authors' standard peripheral arterial imaging method, and more numbers could have been provided, then the samples are surely somewhat inadequate, given that even a basic tool such as Altman's nomogram (before going on to more complex calculations) would suggest sample sizes of 200 for starters, in order to obtain a meaningful analysis. The issue of “no signifi...

Re: Comprehensive MRA of the lower limbs including high-resolution extended-phase infra-inguinal imaging with gadobenate dimeglumine: Initial experience with inter-individual comparison to the blood-pool contrast agent gadofosveset trisodium. A reply
Sir — We are pleased to see non-radiologists taking an active interest in our journal, Clinical Radiology. We are also delighted to engage with fellow enthusiasts of MRA. However, we think Mr Chaudhuri has missed the specific purpose of our investigation, namely high-resolution extended-phase infra-inguinal imaging. Furthermore, this was indeed a pilot study as our concluding paragraph made clear. Following this pilot, we have undertaken a larger prospective study at our institution in which we have included gadobutrol in intra-individual comparisons, and we hope to publish this in the near future.

Venous MR imaging with blood pool agents
AbstractBlood 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 thr...

MRA of the foot with a blood pool agent
AbstractFoot complications associated with diabetes are the most common cause of non-traumatic lower-extremity amputations in the industrialised countries. Revascularisation techniques require precise preoperative imaging. Magnetic resonance angiography (MRA) using gadofosveset trisodium (Vasovist, Bayer Schering Pharma AG, Berlin, Germany) has the potential to detect significantly more patent pedal vessel segments than selective digital substractive angiography (DSA) in an examination with two blinded readers. MRI and MRA are the imaging methods of choice for differentiated assessment of the diabetic foot and its complica...
