Comparative StudyFree-Breathing Radial 3D Fat-Suppressed T1-Weighted Gradient-Echo Sequence for Contrast-Enhanced Pediatric Spinal Imaging: Comparison With T1-Weighted Turbo Spin-Echo Sequence.
The purpose of this study was to compare free-breathing radially sampled 3D T1-weighted gradient-echo acquisitions (radial volumetric interpolated breath-hold examination [VIBE]) with a T1-weighted turbo spin-echo (TSE) sequence for contrast-enhanced spinal imaging of children with CNS tumors. ⋯ For pediatric spinal imaging, radial VIBE images had better image quality and lesion conspicuity and fewer CSF and respiratory motion artifacts than did T1-weighted TSE images in a similar acquisition time.

Can Radiologic Staging With Multiparametric MRI Enhance the Accuracy of the Partin Tables in Predicting Organ-Confined Prostate Cancer?
The purpose of this study is to investigate the accuracy of multiparametric MRI with endorectal coil and Partin tables in predicting organ-confined (OC) prostate cancer in a contemporary cohort undergoing radical prostatectomy (RP) and to assess the possible added value of radiologic staging based on multiparametric MRI to the predictive accuracy of Partin tables. ⋯ The superior predictive accuracy of multiparametric MRI compared with Partin tables to predict OC disease validates the results of smaller previously published studies. Although there is no added benefit of substituting multiparametric MRI stage for clinical stage when using Partin tables, multiparametric MRI staging information is valuable as a stand-alone test.
