Comparative Study
Reduction of patient motion artifacts in digital subtraction angiography: evaluation of a fast and fully automatic technique.
The performance of an automatic technique for the reduction of patient motion artifacts in digital subtraction angiography was evaluated. Four observers assessed the quality of 104 cerebral digital subtraction angiographic images that were processed by means of both the automatic technique and manual pixel shifting. The automatic technique resulted in better image quality and was considerably less time-consuming.

Patients with fluid elsewhere usually have clinically important injury and require further evaluation.
