Multi-head contrast media injectors offer flexible contrast media management, simplified workflows and increased patient safety.
Contrast delivery is much more controlled and efficient when using a dual-head CT power injector. These medical devices are needed to enable the short imaging times typical of multidetector computed tomography (CT) scanners.
Triple-head injectors allow selection of a second contrast agent when two different contrast agents are used, or switching to full contrast agent containers when two identical contrast agents are used.

N1177 is the codename for a nanoparticulate contrast agent under development. N1177 is tested to improve the clinical utility of computed tomography (CT) to diagnose cardiovascular diseases and cancers. N1177 is water insoluble, has an iodine concentration of 67 mg/mL and interacts with activated macrophages. The provider is Nanoscan Imaging, Lansdale, PA.

Omnipaque is a low-osmolar, nonionic, contrast medium with a broad range of indications, for example intravascular diagnostic procedures such as coronary angiography, spinal cord imaging, and body cavity procedures including shoulder and knee joints. Omnipaque is approved for use in adults and children, and is available in a wide variety of packagings.

Omnipaque (iohexol) is a nonionic, low-osmolar contrast agent and is also available for oral use, offering gastrointestinal (GI) visualization with minimal side effects. Omnipaque has a neutral taste that even kids will drink.
Orally administered iohexol is poorly absorbed from the normal gastrointestinal tract. Omnipaque is well tolerated and absorbed if leakage into the peritoneal cavity occurs.
The recommended dosage of undiluted Omnipaque (at a concentration of for example 350 mg/mL) for computed tomography of the abdomen in adults is 500 mL to 1000 mL, diluted to concentrations of 6 mg/mL to 9 mg/mL. The oral dose should be administered about 20 to 40 minutes prior to the CT scan.

Optiray® is a radiographic contrast agent. Optiray® is available in concentrations from 160 to 350 mg/mL organically bound iodine. Optiray® solutions have osmolalities 1.2 to 2.8 times that of plasma (285 mOsm/kg water).
Optiray® 160 is recommended for intraarterial digital subtraction angiography (IA-DSA).
