MR angiography with superparamagnetic iron oxide: feasibility study.
Magnetic resonance (MR) angiography with blood-pool superparamagnetic iron oxide (SPIO) particles was evaluated in the whole-body vascular system. In 12 adult patients, three-dimensional fast imaging with steady-state precession was performed in successive steps from the lungs to the calves before and after a standard dose for liver imaging (15 mumol of iron per kilogram of body weight) of AMI-25. On SPIO-enhanced MR angiograms, visualization of the pulmonary arterial, whole-body, and lower extremity venous systems was graded as good or sufficient in all patients, and femoral vein thrombosis was clearly demonstrated in one patient.
