To determine the characteristics and trends of the original articles published in two major American radiology journals, AJR American Journal of Roentgenology (AJR) and Radiology, between 2001 and 2010. ⋯ The bibliometric analysis of the AJR and Radiology journals with articles published between 2001 and 2010 revealed characteristics and trends of the current radiology research that may provide useful information to researchers and editorial staff in radiology.

To determine whether whole-body total lesion glycolysis (TLG), which combines volumetric and metabolic information from fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT), can provide a better evaluation of the prognosis for non-small cell lung cancer (NSCLC). ⋯ Whole-body TLG is of prognostic value for NSCLC. It may be a promising tool for stratifying patients with NSCLC for risk-adapted therapies.

Comparative Study
Pulmonary lesion assessment: comparison of whole-body hybrid MR/PET and PET/CT imaging--pilot study.
To compare the performance of magnetic resonance (MR)/positron emission tomography (PET) imaging in the staging of lung cancer with that of PET/computed tomography (CT) as the reference standard and to compare the quantification accuracy of a new whole-body MR/PET system with corresponding PET/CT data sets. ⋯ MR/PET imaging of the lung is feasible and provides diagnostic image quality in the assessment of pulmonary masses. Similar lesion characterization and tumor stage were found in comparing PET/CT and MR/PET images in most patients.

To identify patterns of rest functional connectivity (FC) in the whole brain with the default mode network (DMN) soon after stroke and to explore the predictive accuracy of the strength of rest FC in specific areas on poststroke severity of depression and anxiety symptoms. ⋯ These results suggest that a dysfunction of DMN functional connectivity involved in emotional control is associated with the severity of poststroke depression. Further studies are necessary to determine the mechanisms of this functional impairment.

To assess the feasibility of diffusional kurtosis (DK) imaging for distinguishing benign from malignant regions, as well as low- from high-grade malignant regions, within the peripheral zone (PZ) of the prostate in comparison with standard diffusion-weighted (DW) imaging. ⋯ Preliminary findings suggest increased value for DK imaging compared with standard DW imaging in prostate cancer assessment.
