Collateral Status in Ischemic Stroke: A Comparison of Computed Tomography Angiography, Computed Tomography Perfusion, and Digital Subtraction Angiography
Conclusions Concordance between assessments on CT and DSA was poor. Collateral status evaluated on 3-phase CTA and multiphase CTA, but not on DSA, was associated with clinical outcome. (Source: Journal of Computer Assisted Tomography)

Fat-Water Swaps in Iterative Decomposition of Water and Fat With Echo Asymmetry and Least-Squares Estimation Magnetic Resonance Imaging for Postinstrumentation Spine
Objective To determine the frequencies of fat-water swaps in iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) water-only images of the postinstrumentation spine and discuss the efficiency of in-phase imaging in improving visibility of the thecal sac. Materials and Methods A total of 276 patients (167 women; mean age, 62.3 years; range, 23–89 years) with metallic devices on the lumbar spine who received complete routine 1.5 T MR imaging, including axial and sagittal images of T1-weighted, T2-weighted, and T2-weighted IDEAL sequences, were included. The exclusion ...

The Evaluation of Radiomic Models in Distinguishing Pilocytic Astrocytoma From Cystic Oligodendroglioma With Multiparametric MRI
Conclusion Our study showed that gradient boosted trees based on texture features extracted from enhanced T1WI could become an additional tool for improving diagnostic accuracy to differentiate pilocytic astrocytoma from cystic oligodendroglioma. (Source: Journal of Computer Assisted Tomography)

Relationships of Language Lateralization with Diffusion Tensor Imaging Metrics of Corpus Callosum, Tumor Grade, and Tumors Distance to Language-Eloquent Areas in Glial Neoplasms
Conclusions Increased bilateralism in glial masses than normal population and in low grade tumors than high grade and increased nearby tumor settlement in right lateralism and bilateralism support interhemispheric reorganization and plasticity. This is more pronounced in low grade because of higher life span. Highest CC tract number, higher tumor grade, and more remote tumor settlement in left lateralized group suggest intact CC integrity with limited hemispheric destruction. Increasing CC tracts number and FA with increasing tumor grade support preserved CC integrity in the shorter life span of high-grade tumors. (Sou...

Differentiation of Multiple Myeloma and Lytic Bone Metastases: Histogram Analysis
Objective Metastasis and multiple myeloma are common malignant bone marrow lesions. It may be difficult to distinguish because of similar imaging findings. The purpose of this study was to determine the value of histogram analysis on the computed tomography imaging. Methods Twenty-three patients with primary tumor and 23 patients with multiple myeloma were included in the study. All patients had lytic bone lesions on the thorax and abdominal computed tomography scan with contrast. Multiple bone lesions of patients with primary tumor were accepted as metastasis. Multiple bone lesions of patients with multiple mye...
