Contrast agents are part and parcel of everyday radiological practice. Thisarticle provides an overview of current recommendations regarding their useaccording to the European Society for Urogenital Radiology (ESUR, Guidelineson Contrast Media). The Czech Society of Radiology currently does not updateits own recommendations and has accepted the recommendations of the ESUR. ESURhas been issuing these recommendations since 1994 and has since gainedrecognition across radiology societies worldwide. The latest version fromMarch 2018 bears the designation 10.0.
The main points of the latest ESUR recommendations are as follows.Antiallergic premedication of patients is no longer recommended due to lack ofevidence of its effectiveness. Similarly, fasting is no longer recommendedbefore the intravascular administration of low-osmolar or iso-osmolariodinated contrast agents or gadolinium contrast agents. Oral hydration is nolonger recommended as a separate hydration, i.v. administration of NaHCO₃ orNaCl solution is preferred. Diabetics with normal renal function andadministration of iodinated contrast material outside the suprarenal aorta cancontinue to take metformin in the normal regimen. In patients with normalrenal function, the interval between two examinations with iodine orgadolinium contrast material (or a combination thereof) should be at least 4hours. After the administration of iodine and gadolinium contrast agents,lactating women can continue to breastfeed without restrictions.
