Y1 - 2011 N1 - T2 - Venous and Lymphatic Diseases AB - Magnetic resonance imaging (MRI) is an imaging modality for venous diseases that is an alternative to more conventional techniques such as ultrasonography, impedance plethysmography, computed tomography (CT), and invasive selective contrast venography. The advantages of MRI include its noninvasive nature, lack of ionizing radiation and exposure to iodine-based contrast, high spatial resolution, ability to acquire unlimited imaging planes, and its unique ability to perform multicontrast tissue characterization. Despite these advantages, however, routine magnetic resonance venography (MRV) is not widely performed because it generally requires a radiologic team that is familiar with this specialized technique. Also, MRV lacks portability and sometimes incur a higher cost compared with other conventional techniques.
