Reno-60® is radiopaque contrast agent with a wide range of indications. Reno-60 should be at body temperature when injected and may need to be warmed before use. Following intravascular injection, iodinated contrast materials are transported through the bloodstream to the kidneys and excreted by glomerular filtration.

RenoCal®-76 (diatrizoate meglumine and diatrizoate sodium) was used as a contrast agent. Bracco Diagnostics, Inc. stated that the production of Renocal-76 has been discontinued due to reduced demand.

Renografin®-60 (diatrizoate meglumine and diatrizoate sodium) was used as a radiopaque contrast agent. Bracco Diagnostics, Inc. states that the production of Renografin-60 has been discontinued due to reduced demand.

Single-head contrast media injectors ('contrast only') have been first developed in the 1970s. The construction consists of a syringe with the contrast medium inserted into the injector head and a plunger to deliver the contrast medium from the syringe via tubing connected to the patient.
Injectors used in cath lab angiography are often single-head injectors using one syringe.
Angiography contrast delivery systems inject contrast agent into arteries, where air embolisms can present a serious risk. For that reason, cath lab pressure injectors should have air embolism detectors, warning of bubbles in the line before they reach a patient. Air embolisms are not a major issue for CT scans, due to the venous access any small bubbles injected into a vein are expelled through the lungs. Procedures in the interventional suite need low, variable flow rate injections.

Thorotrast is an obsolete contrast medium containing a colloidal suspension of thorium dioxide. Contrast agents based on thorium have been abandoned since they turned out to be carcinogenic.
