Magnetic resonance angiography offers many techniques for study of the carotid district. Time of flight (TOF) is the most widely used technique and can be employed to obtain single slice (2D) or volumetric (3D) images. Our study compared a widely used technique like 2D TOF with the relatively new technique of 3D FGE with bolus administration of contrast medium. From our experience in 20 patients, we conclude that MR angiography with the contrast enhanced 3D FGE offers more detailed information than the 2D TOF technique, thereby justifying its minimum invasiveness and the costs linked to contrast administration. The new technique is a valid alternative to DSA in solving doubtful cases and establishing appropriate treatment strategies.

Abstract
Magnetic resonance angiography offers many techniques for study of the carotid district. Time of flight (TOF) is the most widely used technique and can be employed to obtain single slice (2D) or volumetric (3D) images. Our study compared a widely used technique like 2D TOF with the relatively new technique of 3D FGE with bolus administration of contrast medium. From our experience in 20 patients, we conclude that MR angiography with the contrast enhanced 3D FGE offers more detailed information than the 2D TOF technique, thereby justifying its minimum invasiveness and the costs linked to contrast administration. The new technique is a valid alternative to DSA in solving doubtful cases and establishing appropriate treatment strategies.Pubblicazioni consigliate
