US FDA (Food and Drugs Administation) reminds the Radiology Personnel on the use of Power Injectors to administer contrast media in patient undergoing CT, Angiography and MRI. Misuse of these injectors and the vascular power device may pose harm to patients, which may require surgical intervention.

Power Injectors are use for rapid contrast medium injection in angiography, computed tomography and MRI; these have been used for decades to administer iodinated contrast agents. As magnetic resonance imaging is increasingly being used as an alternative to these methods, it is no surprise to see the success of analogous contrast-enhancement methods which have become routine in MRI.

The FDA warning, which is intended for radiologists, radiologic technologists, and radiologic nurses, includes a number of steps to avoid misuse of these devices. To help prevent the rupture of vascular access devices, the FDA recommends that users of power injectors check the labeling of each vascular access device for its maximum pressure and flow rate. If none is provided, then the user must assume that the device is not intended for power injection and should not be used.
