• Recent NIPH Clinical Trials: Evaluation of the tumor blood flow by computed tomography(CT)perfusion imaging and an effect of chemotherapy or radiotherapy for esophageal cancer
• Uses: It is the raw material for the production of water-soluble, non-ionic X-CT contrast agent in pharmaceutical factory. The trade name of this contrast agent is Omnipaque. This contrast agent is usually injected into the vein before CT angiography to be used for angiography, urinary system, spinal cord and joint, lymphatic system angiography, with advantages of low contrast density, low toxicity and good tolerance type. Iohexol is also currently one of the best contrast agents. The developed countries have completely used it to replace ionography agent. It is also a diagnostic drug. It can be used as non-ionic X-CT contrast agent. Imaging agent antibacterial Imaging agent.
