The purpose of this article is to review the constellation of findings of abusive head trauma, which may be accompanied by injuries to the appendicular and axial skeleton, brain and spinal cord, and retina. Additional common features include skin and soft-tissue injury, visceral findings, and evidence of oral trauma. ⋯ The evidence base for abusive head trauma encompasses diverse disciplines, including diagnostic imaging, pathology, pediatrics, biomechanics, ophthalmology, epidemiology, and orthopedics. When the varied sources of evidence are pieced together and taken in toto, abusive head trauma is often readily differentiated from alternative explanations of an infant's injuries.

Diffusion kurtosis imaging to assess response to treatment in hypervascular hepatocellular carcinoma.
The objective of our study was to compare diffusion kurtosis imaging (DKI) with conventional diffusion-weighted imaging (DWI) for assessing the response to treatment in hypervascular hepatocellular carcinoma (HCC). ⋯ DKI can be a new option for the assessment of posttherapeutic response in HCC.

Percutaneous ablation therapy of hepatocellular carcinoma with irreversible electroporation: MRI findings.
Irreversible electroporation is a new ablation modality. Our purpose was to describe the MRI findings after irreversible electroporation treatment of hepatocellular carcinoma (HCC). ⋯ MRI detects characteristic morphologic and functional changes after irreversible electroporation treatment.

Comparative StudyRadioactive seed localization versus wire localization for lumpectomies: a comparison of outcomes.
The purpose of this study was to compare outcomes of radioactive seed localization (RSL) versus wire localization using surgical margin size, reexcision and reoperation rates, specimen size, radiology resource utilization, and cosmesis as measures. ⋯ RSL is an acceptable alternative to wire localization and offers significant improvements in workflow.

Location of core diagnostic information across various sequences in brain MRI and implications for efficiency of MRI scanner utilization.
Targeting redundancy within MRI can improve its cost-effective utilization. We sought to quantify potential redundancy in our brain MRI protocols. ⋯ High potential redundancy that can be targeted for more efficient scanner utilization exists in brain MRI protocols.
