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.

Randomized Controlled TrialTransverse sinus stenosis in adult patients with Chiari malformation type I.
Transverse sinus stenosis is an imaging finding very highly associated with elevated intracranial pressure (ICP). Patients with the Chiari I malformation may potentially have elevated ICP due to impairment of CSF flow at the foramen magnum. This study evaluated whether patients with Chiari I malformation have transverse sinus stenosis and other imaging findings indicative of elevated ICP. ⋯ Patients with Chiari I malformation have higher likelihood of transverse sinus stenosis, which may reflect associated elevated ICP.

Randomized Controlled TrialChronic respiratory symptoms associated with airway wall thickening measured by thin-slice low-dose CT.
In lung cancer screening, the prevalence of chronic respiratory symptoms is high among heavy smokers. The purpose of this study was to compare CT-derived airway wall measurements between male smokers with and those without chronic respiratory symptoms. ⋯ Male heavy smokers with chronic respiratory symptoms in lung cancer screening, who are at high-risk of chronic bronchitis, have bronchial wall thickening in airways with a luminal diameter of 5-10 mm but not in larger airways.

Randomized Controlled Trial Multicenter Study Comparative StudyPreoperative breast MRI for early-stage breast cancer: effect on surgical and long-term outcomes.
The purpose of this study was to evaluate the effect of the use of preoperative breast MRI on surgical and long-term outcomes among women with early-stage breast cancer undergoing breast conservation therapy. ⋯ Reexcision rates among patients with early breast cancer undergoing conservation therapy were lower among women who underwent preoperative breast MRI. There was no statistically significant effect of the use of preoperative MRI on rates of locoregional recurrence or disease-free survival.
