ExamCard purpose

The 8-channel SENSE NeuroVascular coil was used and SENSE factor 4 was implemented on a 1.5T system at the Radiologisches Zentrum of Speyer that was recently updated to release 2.

 

This ExamCard is intended for CE-MRA of the supra-aortic arteries (e.g. aortic arch, carotid arteries, Circle of Willis) for the imaging of asymptomatic patients (e.g. diabetic patients or peripheral arteriosclerosis). The ExamCard makes use of split dynamics, thus scan 10 and 12 mentioned below are part of one sequence.
