Two techniques to acquire angiographic and venographic information with a single acquisition at 7T were compared: a single echo sequence and double echo sequence. The single echo sequence produced an excellent venography but suffered from some flow losses in the larger arteries due to the long echo time. The double echo sequence produced an excellent angiography and venography but took significantly longer than the single echo technique.
