Randomized Controlled Trial Multicenter Study Comparative StudyAn international multicenter comparison of time-SLIP unenhanced MR angiography and contrast-enhanced CT angiography for assessing renal artery stenosis: the renal artery contrast-free trial.
The unenhanced MR angiography (MRA) technique time-spatial labeling inversion pulse (time-SLIP) may provide a safe alternative for evaluating the renal arteries for stenosis. This international multicenter trial tested the hypothesis that time-SLIP unenhanced MRA is accurate and robust for assessing the renal arteries for stenosis in comparison with contrast-enhanced CT angiography (CTA). ⋯ Compared with contrast-enhanced CTA, the unenhanced MRA technique time-SLIP shows promise for assessing the renal arteries for stenosis. The unenhanced MRA technique time-SLIP may provide a safe alternative for evaluating the renal arteries for stenosis.

Randomized Controlled TrialImproving health literacy: use of an informational brochure improves parents' understanding of their child's fluoroscopic examination.
The purpose of this study was to determine parents' knowledge about pediatric fluoroscopic procedures and potential risk from ionizing radiation before and after being given an informational brochure. ⋯ An informational brochure given to participants before their child's fluoroscopic procedure improved their knowledge of the examination and radiation exposure. No participants refused their child's examination.

Randomized Controlled TrialColonic distention at CT colonography: randomized evaluation of both IV hyoscine butylbromide and automated carbon dioxide insufflation.
The purpose of this article is to evaluate the efficacy of IV hyoscine butylbromide as a bowel relaxant and automated carbon dioxide insufflation in CT colonography in terms of colonic distention and perceived burden. SUBJECTS AND METHODS; Two hundred twenty-four participants were randomly allocated to one of four groups: control (no bowel relaxant and IV saline placebo before CT colonography with manual carbon dioxide insufflation), hyoscine butylbromide (IV hyoscine butylbromide before examination with manual carbon dioxide insufflation), automated (no bowel relaxant before examination with automated carbon dioxide insufflation), and combined (hyoscine butylbromide before examination with automated carbon dioxide insufflation). The degree of colonic distention on a 4-point scale, examination time, and participants' satisfaction, as measured by their responses to a questionnaire, were assessed. ⋯ Colonic distention was statistically significantly improved by automated carbon dioxide insufflation, but not by the administration of hyoscine butylbromide. The participants' tolerance was similar in each group.

Comparative StudyPediatric bone sarcoma: diagnostic performance of ¹⁸F-FDG PET/CT versus conventional imaging for initial staging and follow-up.
The purpose of this study was to compare the diagnostic performance of (18)F-FDG PET/CT and conventional imaging for staging and follow-up of pediatric osteosarcoma and skeletal Ewing sarcoma. ⋯ FDG PET/CT provides diagnostic benefit in Ewing sarcoma and osteosarcoma, with the exception of small lung nodules. Prospective studies are needed to define the best imaging algorithm and combination of tests in the staging and follow-up of patients with pediatric bone sarcoma.

Practice and quality improvement: successful implementation of TeamSTEPPS tools into an academic interventional ultrasound practice.
The goal of this study was to implement an evidence-based teamwork system to improve communication and teamwork skills among health care professionals (TeamSTEPPS) into an academic interventional ultrasound program and to assess safety and team-work climate across team members both before and after implementation. ⋯ The implementation of TeamSTEPPS tools was associated with statistically significant improvements in safety and teamwork metrics in an academic interventional ultrasound practice. The most notable improvements were seen in communication among team members and role clarification. We think that this model, which has been successfully implemented in many nonradiologic areas in medical care, is also applicable in imaging practice.
