The purpose of this article is to discuss common elbow injuries found in pediatric athletes who participate in sports that entail overhead movements with focus on mechanism, clinical features, imaging appearance, and treatment options. ⋯ Elbow injuries are commonly seen in pediatric overhead athletes and have been on the rise owing to the increased participation in and demand of youth sports. Imaging plays a critical role in identifying the type and severity of injury, which helps to determine appropriate treatment options.

Comparative StudyComparison of Triple-Drug Transcatheter Arterial Chemoembolization (TACE) With Single-Drug TACE Using Doxorubicin-Eluting Beads: Long-Term Survival in 313 Patients.
We compared survival outcomes in 313 patients with unresectable hepatocellular carcinoma (HCC) treated with two different transcatheter arterial chemoembolization (TACE) regimens: triple-drug TACE or single-drug TACE using drug-eluting beads. ⋯ We found no significant survival difference in patients with unresectable HCC treated with triple-drug TACE compared with single-drug TACE using doxorubicin-eluting beads.

Lateral Cortical Thickening and Bone Heterogeneity of the Subtrochanteric Femur Measured With Quantitative CT as Indicators for Early Detection of Atypical Femoral Fractures in Long-Term Bisphosphonate Users.
The objective of our study was to compare subtrochanteric femur bone mineral density (BMD) and bone quality of long-term bisphosphonate (BP) users who sustained an atypical femoral fracture (AFF) with BP users who did not sustain a femoral fracture and BP-naïve patients with no history of femoral fracture using quantitative CT (QCT). ⋯ Long-term BP users with a subsequent AFF had a thicker lateral cortex and higher lateral cortex BMDSD at the subtrochanteric area before the fracture on QCT than BP users who did not sustain a femoral fracture and BP-naïve patients.

Comparative StudyAccuracy of Whole-Body DWI for Metastases Screening in a Diverse Group of Malignancies: Comparison With Conventional Cross-Sectional Imaging and Nuclear Scintigraphy.
The purpose of this study is to assess the role of whole-body (WB) DWI as a screening modality for the detection of metastases and to compare it to conventional cross-sectional imaging modalities or nuclear scintigraphy in a population with various histopathologic malignancies. ⋯ WB DWI can be used for screening hepatic and skeletal metastases, but its reliability as the sole imaging sequence for the detection of lymph nodal and pulmonary metastases is poor and, at present, it cannot replace conventional imaging modalities.

Observational StudyIncidence of Inadvertent Dural Puncture During CT Fluoroscopy-Guided Interlaminar Epidural Corticosteroid Injections in the Cervical Spine: An Analysis of 974 Cases.
The objective of this study is to determine the rate of inadvertent dural puncture during CT fluoroscopy-guided cervical interlaminar epidural corticosteroid injection. In addition, in a subanalysis, we aim to assess the rate of inadvertent dural puncture superior to C5-C6 occurring during interlaminar epidural corticosteroid injection using CT fluoroscopy guidance because such injections are not performed using conventional fluoroscopy. ⋯ CT fluoroscopy-guided cervical interlaminar epidural corticosteroid injections were performed at all levels throughout the cervical spine. A very low complication rate and a minimal rate of inadvertent dural puncture were noted, similar to previously reported rates for conventional fluoroscopy-guided injections limited to the lower cervical spine only.
