Why does an MRI take 20 minutes
MRI examinations in radiology
MRI stands for magnetic resonance tomography and is an imaging procedure in radiology that is based on magnetic fields and not on x-rays. This procedure enables fine sectional images of internal organs, soft tissue and bone structures to be created using an MRT examination.
The blood vessels that carry the pulse (arteries) can also be shown very well in the MRI. Even the smallest pathological changes can be diagnosed by looking directly into the body.
In addition to "MRT", the term nuclear spin tomography (nuclear spin) or, colloquially, "tube" is also used.
What is done during an MRI scan?
With every MRT examination, hundreds of images of the body region to be examined are created in millimeter-thin slices in order to diagnose pathological processes or functional disorders in the body.
Which areas of the body are examined with an MRI?
The advantages of the MRI procedure are the representation of organs and soft tissues.
How long does an MRI scan take?
With us, an MRI scan usually takes between 20 and 30 minutes.
For special examinations such as prostate, heart, breast, colon and whole body, the measurement time is around 40 minutes.
Depending on the question, an examination in the magnetic resonance tomograph may require the administration of contrast agent, which is usually administered to the patient via the vein.
How does an MRI examination work?
For an MRI examination, it is necessary that the patient does not wear metal objects on their body, because an MRI is based on a magnetic field. Before an MRI examination, the employees of our team clarify which items of clothing are to be removed before the respective examination so that the corresponding examination cannot be disturbed by metallic parts. If, during an examination, it is necessary for the patient to strip down to their underwear, we will give them a bathrobe that they will wear during the entire examination.
A special examination coil is used depending on which region of the body is being examined. A coil is used to create high-resolution MRI images of the region to be examined.
For an MRI examination, the patient usually lies on his back. Then the appropriate coil for the body region to be examined is attached to the patient. After the patient has been positioned and the coil has been attached, the patient and the examination table are pushed into the MRT machine or "tube" and the examination can begin.
MRI scan of the lumbar spine (lumbar spine)
The patient is informed by the staff at the MRI machine that the examination is starting. The patient then hears the typical knocking noises of the magnetic resonance tomograph.
It is important that the patient lies calmly in the device during the magnetic resonance imaging examination, since movements of the patient can cause image disturbances which could make an exact radiological diagnosis more difficult.
The MRI examination is finished when the staff at the MRI machine informs the patient and the knocking noises stop.
An overview of the MRI examination process:
- Change and then dressed in a bathrobe into the MRI machine
- Position on the examination table in the MRI machine
- Attaching the examination coil
- Driving the patient into the opening of the MRT device
- Examination time 30 and 40 minutes
- Getting out of the MRI machine
- Remove the examination coil
- Leaving the MRI machine
- Evaluation of the MRI examination by the doctor
- Discussion of the results and communication of the diagnosis immediately after the examination
- Summary of the results of the MRI examination in the doctor's report
- Sending of the report and the MRT images to the patient or the referring doctor on the same day
A process is demonstrated graphically in our gallery.
What does an MRI scan cost?
We bill according to the fee schedule for doctors (GOÄ). There are performance indicators for each type of examination. You can see how much an MRI examination costs with us on our cost overview.

The MRI procedure is part of modern radiology
The word radiology originally means "the study of rays". Radiology has developed rapidly since the discovery of X-rays by Wilhelm Conrad Röntgen around 100 years ago. In modern radiology, high-resolution cross-sectional images of the human body can be created by means of an MRT examination based on magnetic fields.
MRI is not only used for diagnostics, but also for interventions such as B. for targeted live-controlled prostate punch biopsies. In addition to the interventions, the MRI procedure also offers the possibility of carrying out targeted treatments.
In addition, the MRT method is of great importance in research and development because it enables a look into the human body and thus answers scientific questions.
Which imaging procedures belong to radiology?
- Magnetic resonance imaging (MRI).
- Computed tomography (CT)
- Angiographies (vascular imaging)
- X-ray, mammography
At the ALTA Klinik we offer examinations using magnetic resonance imaging (MRT), computed tomography (CT) and ultrasound.
