title: The use of gadolinium chelates as an alternative radiographic contrast agent for use with flat panel detector angiography.
abstract: Gadolinium chelates can be utilized as a fluoroscopic contrast agent when iodinated contrast is contraindicated. However, the nephrotoxicity of gadolinium at radiographic doses limits its role as fluoroscopic contrast. Gadolinium chelate-enhanced digital subtraction angiography (DSA) is particularly limited by the kV of DSA, where gadolinium chelates are relatively more radiolucent. Flat panel detectors improve conspicuity of gadolinium chelates during DSA and should be employed where possible.
