The Clinic for Diagnostic and Interventional Radiology has the most modern computer tomographs at its disposal, which make it possible to visualise vascular structures with the highest level of detail.
CT is used in the following areas of neuroradiology, for example:
After contrast medium application via a peripheral vein, the neck and intracranial vessels can be visualised.
CT angiography is primarily used to detect and quantify stenoses (e.g. of the carotid artery or intracranial arteries), but also to visualise vascular protrusions (so-called aneurysms), vascular malformations (e.g. arterio-venous short circuits (fistulas) or to monitor progress after stenting of a narrowing and closure of aneurysms (coiling).

Difficult catheter interventions, especially in the neuro area, require precise planning in order to be carried out with high quality. A speciality of our clinic is the regular performance of pre-interventional planning CT angiographies. This is used in the field of neuroradiology, particularly for carotid stents and aneurysm coiling or vascular occlusion measures in the head and neck area, for example for
- Glomus tumours
- dural fistulas
- carotid stents
- Acute nosebleeds
Thanks to the high rotation speeds and wide detectors of modern CT scanners, it is increasingly possible to assess cerebral perfusion adequately and quickly with CT. This is particularly important in the diagnosis of strokes, when every minute counts before treatment can begin.
Although magnetic resonance imaging is the basic diagnostic method for degenerative spinal diseases, in certain cases invasive diagnostics using myelography is required, which is nowadays regularly combined with CT myelography. On the one hand, this procedure shows the important information of the relationship between bone structures and nerve roots with the highest resolution and precision and also provides dynamic information through functional images.

One of the most common causes of back pain are changes in the small vertebral joints, which mediate movement between the vertebrae and, like all joints in the human body, are subject to degenerative signs of ageing. As these joints lie comparatively deep under the back muscles, they are more precisely accessible for localised drug therapy if the puncture is performed under CT guidance. This is particularly the case in the area of the cervical spine, where important vascular and nerve pathways also run.
