WebThe ionic radius of Gd +3 (108 pm) is very close to that of Ca +2 (114 pm). Free gadolinium is therefore a competitive inhibitor of physiologic processes that depend on Ca +2 influx, including voltage-gated calcium channels and the activity of some enzymes. All Gd-based MR contrast agents therefore use some sort of ligand to chelate (contain) the free ion … WebT1 - Effect of bolus administration of non-ionic radiopaque contrast media on blood pressure variation.
