Single Echo Simultaneous Angiography and Venography (MRAV) Techniques at 3T

Introduction: Several techniques have been presented in the last year to acquire both angiographic and venographic information in a single acquisition (MRAV) using susceptibility weighted imaging (SWI). However, these techniques either require a double echo acquisition (1) or a single echo with flip angles that tend to compromise the quality of either the angiography or venography (2). In this work we develop novel acquisition and post processing techniques to improve the quality of single echo MRAV acquisition. The ability to collect MRAV data is an important clinical goal for analyzing a variety of clinical diseases including: stroke, trauma, tumors and multiple sclerosis.
