OBJECTIVE: The purpose of this study was to evaluate the usefulness of MRI and MR angiography for the assessment of @entity1095 compared with the usefulness of conventional duplex sonography, venography, and arteriography. SUBJECTS AND METHODS. Nineteen @entity1 (age range, 8-64 years; 11 males and eight females) with clinically diagnosed or suspected @entity854 of the extremities were examined on a 1.5-T whole-body MR scanner. Using parameters based on a fast localizer sequence, we acquired transverse or coronal T1-, T2-, short tau inversion recovery (STIR), and contrast-enhanced T1-weighted images. Dynamic contrast-enhanced three-dimensional (3D) gradient-echo MRIs were acquired to determine the extent and type of the @entity2758 for each @entity1 . MR data sets were evaluated for lesion depiction, determination of the extent of the @entity600 , involvement of neighboring structures, vascular detail, and treatment planning. Results were compared with findings from duplex sonography, venography, and intraarterial digital subtraction angiography. RESULTS: All MRIs were of diagnostic quality and revealed 12 @entity455 , four @entity2758 , and three @entity2695 . The STIR sequence was helpful for determining the extent of the @entity1462 , which was often underestimated using contrast-enhanced 3D MR angiography alone, whereas dynamic contrast-enhanced 3D MR angiography was required for classifying the type of the lesion. MR angiography was inferior to conventional angiography for revealing vascular detail and for planning intervention. CONCLUSION: MRI and MR angiography appear to be valuable for the assessment of @entity1462 of the extremities. The protocol for imaging such malformations should combine dynamic contrast-enhanced 3D gradient-echo MRI with STIR sequences. However, digital subtraction angiography and venography are still required for definitive treatment decisions.
