Objectives: To evaluate the utility of gadolinium enhanced three dimensional magnetic resonance angiography for different vascular territories of the body in comparison to x-ray angiography and to present our preliminary experience in the optimal use of the technique. Materials and Methods: The study evaluated 30 consecutive patients who underwent contrast enhanced MR angiography for different indications. Contrast enhanced MRA was performed on 1.5 Tesla MR system (Magnetom Vision, Germany) using 3D-Flash sequences. Coronal dynamic MRa was performed after injection of the contrast bolus and the images obtained were reconstructed using maximum intensity projections. Twenty patients underwent DSA of 23 vascular territories after CE MRA. Five patients underwent surgery. All the studies were interpreted by two qualified radiologists in consensus. Results: CEMRA was 100 per cent sensitive in picking up aneurysmal and stenotic lesions. The specificity for complete occlusion and aneurysmal disease was also 100 percent, but for partial stenosis the specificity was 83.3 percent related to overestimation of stenosis. CEMRA offered a global view of vascular pathology precisely vessel stenosis, collateral formation and distal run-off, aneurysmal disease and the relation of different branches to the aneurysm from multiple projections. Conclusion: CEMRA should be considered an attractive and artifact-free advancement of MRA techniques, which besides surpassing the old unenhanced MRA techniques should tend to replace DSA for diagnostic purposes.
