Vascular imaging as gentle as possible – that is our primary target for all vessel related issues. In general, blood vessel imaging can be done with catheter angiography under x-ray, non-invasively with computer tomography, or even completely without radiation exposure under magnetic resonance imaging. For this procedure, a contrast medium is typically injected into the blood vessel in order to visualize its interior. For a catheter angiography, the contrast medium is injected through a small plastic tube that is inserted into the vascular system via an inguinal or elbow vessel and then advanced into the respective tissue section. The disadvantage of this procedure is its rather invasive approach. However, the advantage is that vascular stenoses (constrictions) can be reopened in the course of this intervention. For a CT or MRI scan, the contrast medium is injected into an arm vein through a small indwelling cannula. The contrast media used usually contain iodine (computer tomography / catheter angiography) or gadiolinum (magnetic resonance imaging) Further information about contrast media can be found in the Contrast Media section.
Under magnetic resonance imaging angiographies without contrast medium are possible as well. This constitutes a very gentle and non-invasive examination technique that does not involve any vessel punctures. However, not all medical issues can be satisfactorily and adequately diagnosed with this technique.
The primary application of angiography is the assessment of various vascular disorders such as arteriosclerosis, coronary heart disease, peripheral occlusive disease, inflammatory alterations of the vascular wall (e. g., lupus erythematodes), aneurisms, and dissections as well as venous diseases such as thrombosis or varicose veins.
