Radiology. Our Specialisations
Extensive diagnostics and examination procedures.
Dear patients, relatives, visitors and interested parties,
imaging procedures, such as conventional x-rays, digital subtraction angiography (DSA), computer tomographies and magnetic resonance imaging (MRI), are available for rapid and conclusive diagnostic testing. Our modern equipment keeps the radiation exposure as low as possible and may prevent exposure altogether, as is the case with magnetic resonance imaging. The following equipment is available for the diagnostic testing of outpatient and inpatients.
In conventional x-rays, images are taken of the bones and the thorax (heart and lungs). We also carry out special procedures.
Myelography: A myelography is a diagnostic procedure that visualises the subarachnoid space in the spinal column using x-rays. A water-soluble contrast agent is injected into the subarachnoid space (membrane surrounding the spinal cord) and an x-ray is used to show the spread of the contrast agent. By looking at the spread of the contrast agent in the spinal canal it is possible to see how much space is available for neural tissue within the bony canal.
Functional images of the spine for scolioses
Fluoroscopies to show the gastrointestinal tract, lungs, joints, fistulas and to check the shunt valves used for the drainage of cerebrospinal fluid or the like
Angiography and DSA.
The digital subtraction angiography is a computer-assisted examination method used to visualise basically every artery and vein in the body. The blood vessels can be visualised by injecting a contrast agent through a thin, flexible plastic catheter. The catheter is placed in an artery in the groin or arm following the administration of a local anaesthetic. X-rays are used to check the position of the catheter and to visualise the blood vessels.
Special usage of angiography and DSA
Cerebral angiography (e.g. for brain haemorrhages)
Wada test (to establish on which side of the brain the speech and cognitive centres can be found)
PTA (to widen a narrowed artery)
STENT treatment (a prosthesis for blood vessels, e.g. to widen the aorta)
With the help of the automatic CARE dose 4D programme, the ultra rapid and high resolution 16-slice computer tomography (CT) scan makes sure that every patient and every region of the body receives only the smallest amount of radiation possible.
Special examinations using computer tomography
- 3D reconstructions
- Navigation for computer-controlled surgery to the spine and head
- CT angiography
- CT-guided interventions:
- Infiltration treatment
- Removal of tissue
- Drainages to decrease pressure
Magnetic resonance imaging.
Magnetic resonance imaging (MRI) scans do not require the use of x-rays. The head, spine, limbs and abdomen are the parts of the body most frequently examined.
Special examinations using magnetic resonance imaging
- MR angiography (instead of an examination with a catheter)
- MRI of the breast
- MRI of the bile ducts, pancreatic ducts, ureter, etc.
- Functional MRI of the brain
Special attention to the diagnosis in children.
As a rule, the equipment we use in our diagnostic methods emits low levels of radiation. In paediatrics we make every effort, in particular, to consider the special needs of our young patients.
Paediatric Orthopaedics – Developmental disorders in the musculoskeletal system
Unlike adult patients, the cooperation of a child when performing the necessary imaging procedures can be very varied depending on age and development. So that the images obtained are still conclusive, such examinations are performed away from routine practice, in relaxed surroundings.
It is highly beneficial for a family member to be present, as well as a doctor or nurse from the paediatric unit with whom the child is familiar. Sometimes an anaesthetic is needed to calm the patient in readiness for the magnetic resonance imaging or computed tomography (MRI/CT) scan. On account of the very varied imaging properties of the musculoskeletal system and its particular pathologies, which are dependent on the child's age, an exceptional degree of scientific and clinical expertise is available in the Departments for Radiology and Paediatric Orthopaedics.
Neuropaediatrics – Epilepsy Diagnostics
One aspect of childhood epilepsy is caused by a focus in the brain, which can possibly be removed by surgery. In addition to clinical and EEG/video-assisted long-term assessment of childhood epilepsy, and searching for the focus using nuclear medicine, high-resolution MRI and functional MRI are further important diagnostic elements.
MRI procedure in children
High-resolution MRI is performed under anaesthetic, taking 1 mm thin layers and examination periods of up to 2 hours. For this purpose, the Department for Anaesthesia has a team of staff specially trained in paediatric anaesthesia. It is also very important to demarcate a proven, and possible surgically removable, convulsion-inducing focus from critical brain centres. Hence, a functional MRI of the brain is performed in cooperation with Head of Department Prof. Dr. M. Staudt.
