Question: 1 / 400

What is the effect of using a power injector at a higher rate of rise?

Increased catheter whip

Increased risk of contrast-induced nephropathy

Improved visualization during angiography

Decreased likelihood of vascular injury

Using a power injector at a higher rate of rise can indeed lead to improved visualization during angiography. When the injector delivers contrast at a rapid rate, it enhances the flow dynamics within the blood vessels, which can result in more uniform and timely distribution of contrast material. This improved opacification allows for clearer images and better delineation of vascular structures, aiding in the diagnostic process.

Rapid injection rates can help achieve optimal filling of the vascular space, ensuring that the contrast agent reaches its intended area more efficiently. This enhanced visualization is crucial for accurately assessing conditions such as blockages, aneurysms, or malformations during angiographic procedures.

The other options, while they touch upon important considerations in angiography and catheter use, do not directly connect to the benefits of using a power injector at a higher rate of rise in terms of image quality and clarity during diagnostics.
