ReviewRevisiting neuroimaging of abusive head trauma in infants and young children.
The purpose of this article is to use a mechanism-based approach to review the neuroimaging findings of abusive head trauma to infants. Advanced neuroimaging provides insights into not only the underlying mechanisms of craniocerebral injuries but also the long-term prognosis of brain injury for children on whom these injuries have been inflicted. ⋯ Knowledge of the traumatic mechanisms, the key neuroimaging findings, and the implications of functional imaging findings should help radiologists characterize the underlying causes of the injuries inflicted, thereby facilitating effective treatment.

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.

Comparative StudyPET/MRI for the evaluation of patients with lymphoma: initial observations.
The objective of our study was to assess the role of recently introduced hybrid PET/MRI in the evaluation of lymphoma patients using PET/CT as a reference standard. ⋯ PET/MRI can be used to assess disease burden in lymphoma with sensitivity similar to PET/CT and can be a viable alternative for lymphoma staging and follow-up.

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.
