MR Angiography of the Renal Arteries

MR Angiography of the Renal Arteries

High blood pressure (hypertension) is a common diagnosis. If your high blood pressure is hard to manage, we recommend eliminating doubt about a possible so-called "secondary cause" of the sickness. Since abnormalities in the renal vessels (e.g. constrictions, so-called stenoses) or in your kidneys or adrenal glands are frequent in cases of high blood pressure, an examination of your kidneys and their blood vessels is necessary. 

Vascular imaging by means of MRI enables us to conduct a variety of examinations in one single procedure without employing any X-rays:

  • MR angiography of the abdominal artery and renal arteries with a contrast agent based on gadolinium 
  • kidney perfusion by means of a dynamic measurement of the concentration of the contrast agent
  • excretory urography by means of delayed imaging
  • depiction of the renal parenchyma 
  • depiction of the perirenal structures (adrenal glands, lymph nodes, etc.)

In this procedure, only a high-pressure infusion into one of your arm veins with about 15 to 20 ml of contrast agent is necessary. Parts of this examination can also be performed by means of a color-coded duplex sonography of the renal arteries.
