High-quality images without radiation – only magnetic resonance imaging (MRI) can do that.
The strong magnetic field of magnetic resonance tomography causes the hydrogen atoms of the patients to rotate in the same direction during the examination in the human body (which consists largely of water), and a radio signal causes them to oscillate. The resulting response signals provide finely graded slice images. As an examination without radiation exposure, magnetic resonance can also be used as an imaging procedure for pregnant women and children.
Magnetic resonance imaging MRI are provided by Diagnoseinstitut Alsergrund GmbH. These MRI Vienna are to be paid privately, and the cost of the examination can be submitted to a supplementary insurance/private insurance.
Of course, patients can choose to have their magnetic resonance imaging MRI examination performed by either Dr. Sailer or Dr. Peloschek.
Depending on age and gender, humans consist of approximately one to two thirds water. The hydrogen atoms (protons of water) as well as the protons in the solid parts of the tissues are tiny magnets whose properties are exploited by the MRI machine for imaging:
Patients are placed in a very strong magnetic field (currently 1.5 tesla, about 15,000 times stronger than that of Earth) for MRI examination so that their protons spin predominantly in one direction. Then their protons are vibrated with a radio signal so that they in turn emit radio signals that are measured by antennas (called coils that are placed on the body). These signals in the MRI machine are converted into slice images by the computer.
Magnetic resonance imaging examination is performed without X-rays and thus can be used without hesitation in children and – in case of special questions – also in pregnant women. Occasionally, contrast medium (gadolinium) is required to differentiate between individual structures and between healthy and diseased tissue. Adverse side effects occur much less frequently compared to contrast agents used in computed tomography.
The Radiology Center performs the following MRIs:
- Examination of the brain, spinal cord, skull, facial skull, paranasal sinuses.
- MR angiography (cerebral basal arteries, carotid artery, aorta, renal arteries, iliac arteries)
- Examination of breast tissue, mammary MRI (including biopsy or marking if needed)
- Magnetic resonance imaging of liver, bile ducts, pancreas, kidneys, uterus, ovaries, prostate, intestines, spine, full body MRI (i.e. body trunk MRI) and examination of all joints
