The group Experimental Radiology at the Department of Radiology in the University Medical Center has an opening for a

PhD Student for MR-guided Interventions with Vein Stents (M/F/d):

Magnetic resonance imaging (MRI) is the diagnostic imaging method of choice for many diseases, as it provides 2D and 3D cross-sectional images with excellent contrast between different tissues, and it offers functional information without using ionizing radiation. In addition, MRI can be used for real-time imaging during interventional procedures such as the harvesting of biopsy samples or the placement of stents in the arteries. MR-guided interventions are difficult to perform, because the bulky magnet severely limits the access to the patient, all devices need to be fully non-magnetic, and rapid real-time image acquisitions need to be realized.
In a BMBF-funded project we are investigating whether it is possible to place a novel stent system in the veins of the lower pelvis fully under MR-guidance. Compressed iliac veins in the pelvis which can lead to severe swelling of the legs (May Thurner syndrome)
for this disease vein stents can be an excellent treatment option. Vein stents differ significantly from stents used in arteries, as the retentive forces of the venous vessel wall are much lower than in the arterial case.
In this context we will develop new MRI methods to detect, monitor and quantify the release of the vein stent during the interventional procedure in real time. The imaging methods will be tailored to overcome the limited RF penetration into the stent meshes, and they will also take into account real-time tracking of the delivery device for the vein stents. For this, new pulse sequences will be developed, phantom setups will be created, and velocity measurements will be performed to assess the change in blood flow after stent implantation.
