Peripheral MR Angiography

摘要

Since the introduction of contrast-enhanced MR angiography (MRA), several different techniques for imaging the peripheral arteries have evolved. All of them provide good diagnostic image quality, whereas some older techniques suffer from drawbacks, such as long acquisition time, impaired image quality from venous enhancement, and limited spatial resolution. MRA provides the most comprehensive modality offering the ability to tailor the examination to the patient and the specific question to be answered. The drawbacks experienced at the introduction of MRA to clinical routine have largely been overcome or at least diminished, so that the benefits of MRA outbalance the limitations.
