Introduction
An MRI of the kidney is the best way to visualize the kidneys. It can be performed either with or without contrast medium. An MRI of the kidney is performed if the following kidney diseases are suspected:
- Unclear space requirement of kidney renal enlargement
- Kidney cancer
- Inflammation of the kidney (e.g. inflammation of the renal pelvis)
- Unclear high blood pressure
- Renal artery stenosis
What is the procedure for an MRI examination of the kidney?
Magnetic resonance imaging of the kidneys is currently the best diagnostic tool for imaging both organs. It is primarily used to clarify unclear masses that are discovered in addition to the findings or during an ultrasound examination. The magnetic field strength used to assess the kidneys is usually three tesla.
Magnetic resonance imaging, as the MRI is also called, is performed lying on your back. Before the examination, it is important to remove all metallic objects on the body. In this way a disturbance of the magnetic field is avoided.
If necessary, Buscopan© can be administered before the examination to calm down the gastrointestinal activity. If there is fear of confined spaces, a fast-acting sedative can be taken. The examination couch “drives” into an open, well ventilated tube.
Throughout the entire examination, video-assisted monitoring of the patient is carried out by the staff. They communicate with the patient via a loudspeaker system, who can respond at any time and draw attention to himself with a bell. During the examination, verbal communication is not possible due to the volume, so the bell is an alternative.
The loud, rhythmic knocking of the MRI can be prevented with the help of hearing protection. The patient should lie still during the examination and hold his breath briefly on the staff’s command. Contrast medium can be applied through a vein if necessary. If there is suspicion of a change in the urinary tract system, renal function is triggered with the help of a specific medication. In this way, for example, any obstruction in the urinary tract drainage system can be diagnosed.
