3D Contrast MR Angiography
Non-invasive, high resolution contrast arteriography without arterial catheterization or nephrotoxicity has become possible using paramagnetic contrast agents and high performance MR imaging systems. The success of this technique is reflected by its rapid integration into clinical practice throughout the world. Three-dimensional (3D)contrast MRA has quickly expanded to encompass virtually all vascular territories using a variety of magnets and imaging strategies. The rapid evolution of this technique is also reflected in the expanded volume of this second edition. Beyond familiarizing the reader with the basic principles underlying 3D Contrast MRA, all relevant technical aspects are addressed, potential pitfalls are identified, and tailored imaging strategies for different vascular regions are described. To widen the scope, the 2nd ed. of 3D Contrast MRA includes invited case studies performed by renowned investigators. The description of imaging techniques have been standardized to facilitate implementation into clinical practice.The glossary of relevant terms and the extensive bibliography has also been expanded.
