Individual examination procedures and suggestive application areas

1. Magnet-Resonance-Tomography

Using the MRT the most orthopedic and nurologic problems can be answered. Often there are certain application areas in ENT medicine, ophthalmology, angiology and internal medicine, gynaecology and urology (liver, kidney, adrenal gland, thyroid gland, pelvis, uterus and adnexa, prostata and the whole vasuclar system (arteries and venes).

High field MRT (3 Tesla)

The new high field MRT is designed more patient-friendly, compared to older pieces of equipment. It is more light-coloured, the magnet is shorter and the opening is bigger, so that its design is similar to the CT’s.
Thus it usually is no problem for a patient suffering from agoraphobia to perform an examination. In such a case, a light sedation can be made.

An examination takes about 20 to 50 minutes depeding on each particular problem. When examining unsettled patients, patients with strong agoraphobia and anxious or unsettled children there is an opportunity of running through ultra-fast sequences, which can shorten the length of the procedure very effectively. Although this implies a lose in image quality and resolution, there still are sufficient information for diagnostic uses. Additionally, for smaller children the so-called “Flüstersequenzen” are available, which are used if the children are supposed to sleep.

General application possibilitiesof the MRT:


  • Anatomic illustrations of soft part organs of the whole body or bones and thir pathologic changes

Functional MRT:

  • Perfusion and diffusion examtions occuring with circulatory disorders and appoplexia (Blood volume, reserve capacity)
  • Illustration of function areals: The brain’s speech centrum, motoic and sensible tracts, optic tract (e.g. impaired visions / Anopsies)

MRA (Magnet-Ressonance-Angiography):

  • Indisposition of extra – and intracranial vessels, Aorta and kidney vessels, vells of the arm, leg of pelvis (including lower leg arteries)
  • In many cases this imposes an alternative to the i.a. DSA

When are contrast agents used in MRT?

  • It is not always necessary, as there are other indications than in a CT
  • There are no negative side-effects occuring with the hyperthyreose, very rare allergic reactions
  • Coming up with inflammation an turmours it mostly is necessary, as well as with some forms of MR angiographies (aortic arch, leg and pelvis angiographies)

Specific Application Areas:

Diseases with intracranial mafifestation, cranial base, petrous bone, orbita, neck (ENT; eyes, neurology, neurosurgery, psychiatry, pediatry)

  • Development disorders, performance disorders with children (brain development, myelinogenesis, leukoencephalopathy)
  • Circulatory disorders (Apoplexy), vascular demence
  • Demential diseases (Alzeheimer’s disease)
  • Neurologic system diseases (Neurofribromatosis, chorea, tuberous sclerosis, sturge-weber syndrome, etc), neuro-degenerative diseases
  • Morbus Parcinson, Multiple sclerosis
  • Inflammable diseases (also collagenosis etc: Sarcoidosis, lupus erythematodesis, PCP with cerebral and/or cranial manifestation)
  • Vascular abnormanism, aneurysm
  • Brain tumours, tumour suspicion: Primary brain tumours, metastasis
  • Acoustic neuroma, pituitary adenoma, meningioma, etc

Intervertebral disk processes, spinal space occupying lesion, spinal inflammation, metastasis in the spinal column, spinal marrow diseases

ENT and ophthalmology: All Cranial base, orbita and neck processes, partly: Retinal diseases (Tumours, bleedings), optic nerve changings, optic track processes, eye muscles, endokrine Orbitopathy

Diseases considering te Moving Apparatus (Orthopedics, Surgery, Neurosurgery)

  • All muscle-skeletal diseases (spinal coulumn and extremities), particularly inflammable and development conditional diseases
  • Articular, band and chondral diseases, bone diseases
  • Osteonecrosis, traumatology
  • Osteomyelitis, spondyloscitis, bones and spinal abscesses

Internal Medicine, oncology, gynecology, urology:

  • Particularly well suited is the MRT considering liver, pelvis and chest diseases
  • MRCP: Non-invasive illustration of the gall and pancreas tracts (without using a contrast agent)
  • Less well suited ist the MRT considering intestinal processes
  • An indication in future will be a heart examination (coronary vessels). A morphologic-anatomic illustriation is well possible, already.

2. Computer Tomography

Sequential CT, Spiral-CT, Angio-CT, 3D-CT, Cardio CT, Intervention-CT
Using ceramic detectos available the radiation dose can be reduced significantly. A specific software allows a coronary lime illustration of the heart, another specific measure and examination software allows the use of lower contrast agents (so-called CARE-Bolus).

Application areas:

  • Cerebral circulatory disorders (Micro and Macro angiotherapy)
  • Acute cerebral hemorrhage (parcticularly in case of an assumed subarachnoid hemorrhage
  • Cranial base and petrous bone processes (internal ear)
  • Traumatic head-brain-diseases (subdurale and epidurale hematoma)
  • Infections of the invertebral discs, local spinal column processes, fractures
  • Cervical soft parts
  • CT of the lung and mediastinum (HR-CT in case of lung fibroses)
  • Abdonem illustration (liver, kidney, adrenal gland, intestines, pelvis)
  • Joints (In case of specific problems)
  • Illustration of the intracranial vesicles, neck vesicle (Carotis), the aorta and kidney arteries (e.g. search for aortic anorism)
  • Cardio-CT: Sequential CT with EKG triggering to prove a calcification of cornary vesicles as indication for coronary angiostenosis, follow-up after dilatationes, re-stenosis near to stents (Particlulary in connection with exercise-myocardic-scintigrapy).
  • Alternative MRT examinations for patients with a cardiac pacemaker

3. DSA

  • Intra-aterial vescile illustration of head-neck, abdominal and extremity ateries (In many cases possible under ambulant conditions)
  • Dilitations, stents, anerysma and AV fistels as well as angioma embolisation, acute medical treatment (Fibrinolysis) of apoplexies (in cooperation with the neurology and intensive care unit of the “Rheinische Klinik”
  • Phlebographies

4. Ultra-sonic

Colour Doppler, Power Doppler, extra and transcranial Doppler, Duplex Sonography, intracranial B-Scan, thyroid gland, neck soft parts, abdomen, pelvis, extremities, etc

5. Mammography

All current problems, particulary medically indicated pre and follow-up examinations

6. Convential X-Ray procedures

All classic application areas

7. Nuclear Medicine

  • Myocardic-Scintigraphy
  • Bone scintigraphy
  • Thyroid examination programm
  • Laboratory (Thyroid gland, tumour marker, hormones)

8. PET (Positron-Emission-Tomography)
