摘要：
We developed a dynamic magnetic resonance (MR) angiographic imaging protocol that can aide the diagnosis of subclavian steal syndrome (SSS). Our protocol combines a new pulse sequence: time-resolved echo-shared angiographic technique (TREAT) with parallel imaging: generalized autocalibrating partially parallel acquisition (GRAPPA). Our pulse sequence, like traditional catheter angiography exams, provides anatomic and dynamic flow pattern information in one scan. If included in comprehensive SSS MR imaging examinations, this sequence can potentially reduce the need for diagnostic X-ray angiography. (C) 2008 Elsevier Inc. All rights reserved.
