Honorary authorship in radiologic research articles: assessment of frequency and associated factors.
To quantify the frequency of perceived honorary authorship in radiologic journals and to identify specific factors that increase its prevalence. ⋯ http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11101500/-/DC1.

Clinical Trial
Arthroscopic partial meniscectomy: MR imaging for prediction of outcome in middle-aged and elderly patients.
To determine whether preoperative magnetic resonance (MR) imaging could help identify factors associated with poor clinical outcome after arthroscopic partial meniscectomy (APM) in middle-aged and elderly patients with meniscal tears. ⋯ Poorer clinical outcome after APM was associated with greater severity of cartilage loss and bone marrow edema in the same compartment as the meniscal tear, greater severity of meniscal extrusion, greater overall severity of joint degeneration, a meniscal root tear, and a longer meniscal tear at preoperative MR imaging.

To evaluate the effectiveness of a staged ultrasonography (US) and computed tomography (CT) imaging protocol for the accurate diagnosis of suspected appendicitis in children and the opportunity for reducing the number of CT examinations and associated radiation exposure. ⋯ A staged US and CT imaging protocol in which US is performed first in children suspected of having acute appendicitis is highly accurate and offers the opportunity to substantially reduce radiation.

To verify iliolumbar ligament (ILL) location, to evaluate magnetic resonance (MR) imaging morphologic features for detecting lumbosacral transitional vertebrae (TVs) (LSTVs), and to determine whether transitional situations are associated with anomalous vertebral numbering. ⋯ The ILL denotes the lowest lumbar vertebra, which does not always represent L5. A well-formed, complete S1-2 intervertebral disk is associated with LSTVs, but alteration in LSIVDA is not. LSTVs are associated with anomalous vertebral numbering.
