Comparative Study
PET/CT findings for tumors in the base of the skull: comparison of 18 F-FDG with 11 C-methionine.
Positron emission tomography/computed tomography (PET/CT) using 18 F-fluorodeoxyglucose (FDG) has been used to characterize various malignancies. There are few reports regarding the use of 11 C-methionine (MET)-PET/CT to characterize tumors in the skull base. ⋯ MET-PET/CT showed superior inter-rater agreement and had higher uptake for tumors at the skull base than FDG-PET/CT. The present study suggests that MET-PET/CT has superior potential for imaging of tumors of the skull base.

Randomized Controlled Trial
Computed tomography in trauma patients using iterative reconstruction: reducing radiation exposure without loss of image quality.
Rising numbers of computed tomography (CT) examinations worldwide have led to a focus on dose reduction in the latest developments in CT technology. Iterative reconstruction (IR) models bear the potential to effectively reduce dose while maintaining adequate image quality. ⋯ ASIR contributes to a relevant dose reduction without any loss of image quality in a dedicated WBCT protocol for patients with multiple trauma.

From a surgical perspective, presurgical prediction of meningioma consistency is beneficial. ⋯ Our results suggest that a quantitative assessment using conventional T2W imaging or FLAIR may be a simple and useful method for predicting hard meningiomas.

Many imaging methods have been defined for quantification of hepatic steatosis in non-alcoholic fatty liver disease (NAFLD). However, studies comparing the efficiency of magnetic resonance imaging-proton density fat fraction (MRI-PDFF), magnetic resonance spectroscopy (MRS), and liver histology for quantification of liver fat content are limited. ⋯ Both MRI-PDFF and MRS can be used for accurate quantification of hepatic steatosis.

Accurate evaluation of the spleen is an important component of staging lymphoma, because this may have prognostic and therapeutic implications. ⋯ Whole-body MRI-DWI is reasonably accurate in the detection of splenic lymphomatous involvement.
