3D Contrast MR AngiographyNon-invasive, high resolution contrast arteriography without arterial catheterization or nephrotoxicity is possible using Gadolinium contrast and an MR scanner. The success of this technique is reflected by its incorporation into clinical practice in centers throughout the world. It has been applied to multiple vascular territories, using a variety of magnets, and imaging strategies. A thorough understanding of the underlying mechanisms and proper technique are essential to fully exploit the diagnostic potential of this new form of angiography. This book will familiarize the reader with the basic principles of 3D Contrast MRA. All relevant technical aspects are addressed, imaging protocols are provided, and tailored imaging strategies are described for different vascular regions. The book also includes a glossary. |
