X-ray systems are widely used for blood vessel imaging because of their high imaging resolution. They have, however, two drawbacks: they expose patients to radiation, and a contrast medium needs to be injected into the blood system. Although MRI systems are completely safe, the images they produce lack the resolution of X-ray images since rapid signal fall-off makes clear vessel images difficult to acquire. Our new imaging method shortens the time taken to capture the NMR signal. This improves resolution to a level where blood vessels only 0.1 mm wide can be imaged using an experimental system (magnetic field strength 4.7T , bore size 30 cm), the highest resolution level ever achieved by a MRI system.
