Randomized Controlled Trial
Image noise reduction algorithm for digital subtraction angiography: clinical results.
To test the hypothesis that an image noise reduction algorithm designed for digital subtraction angiography (DSA) in interventional neuroradiology enables a reduction in the patient entrance dose by a factor of 4 while maintaining image quality. ⋯ In DSA, a change in technique factors combined with a real-time noise-reduction algorithm will reduce the patient entrance dose by 75%, without a loss of image quality.

Randomized Controlled Trial
Global small bowel motility: assessment with dynamic MR imaging.
To assess the repeatability in human volunteers of software-quantified small bowel motility captured with magnetic resonance (MR) imaging and to test the ability to detect changes in motility induced by pharmacologic agents. ⋯ http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.13130151/-/DC1.
