[Magnetic resonance angiography--a new procedure for vascular imaging in the area of the head-neck].
Some six or seven years ago, digital subtraction angiography (DSA) was introduced as a new diagnostic tool in the evaluation of vascular lesions. In the diagnostic management of vascular disorders in the head and neck, DSA could replace conventional angiography almost completely. Now, a new angiographic technique has been developed--magnetic resonance angiography (MRA). In the present study 60 patients with vascular lesions of head and neck were examined with both DSA and MRA in order to compare the diagnostic value of these techniques. Our results indicate that MRA is at least equivalent in the evaluation of vascular disorders in head and neck region. In addition, the advantages of MRA compared to DSA are the following: (1) MRA is a non-invasive technique, thus reducing the angiographic risk. (2) MRA offers the possibility of multiplanar imaging. (3) MRA can be performed simultaneously with MRI if necessary. (4) Compared to other angiographic techniques the patient will not be exposed to radiation.
