Noncontrast‐enhanced magnetic resonance angiography and venography imaging with enhanced angiography

PURPOSE: To achieve simultaneous high-resolution magnetic resonance angiography and venography (MRAV) imaging in terms of enhanced time-of-flight (TOF) angiography and susceptibility-weighted imaging (SWI), with a clear separation of arteries and veins. MATERIALS AND METHODS: A new flow rephase/dephase interleaved double-echo sequence was introduced that facilitates multiple types of imaging contrast, i.e., TOF, SWI, and dark blood, in a single …
