Systematic review on the characterization of chronic traumatic encephalopathy by MRI and MRS.
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease that is found in people who have suffered from chronic traumatic brain injury (TBI). Up to now, diagnosis of CTE could only be made based on postmortem histopathological examinations. The application of MR techniques might offer a promising possibility for in vivo diagnoses. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;49:212-228.

Radiomic signature as a predictive factor for lymph node metastasis in early-stage cervical cancer.
Lymph node metastasis (LNM) is the principal risk factor for poor outcomes in early-stage cervical cancer. Radiomics may offer a noninvasive way for predicting the stage of LNM. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;49:304-310.

Preoperative prediction of sentinel lymph node metastasis in breast cancer by radiomic signatures from dynamic contrast-enhanced MRI.
Sentinel lymph node (SLN) status is an important prognostic factor for patients with breast cancer, which is currently determined in clinical practice by invasive SLN biopsy. ⋯ 1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;49:131-140.

Ultra-high-b radial diffusion-weighted imaging (UHb-rDWI) of human cervical spinal cord.
Injury in the cervical spinal cord (CSC) can lead to varying degrees of neurologic deficit and persistent disability. Diffusion tensor imaging (DTI) is a promising method to evaluate white matter integrity and pathology. However, the conventional DTI results are limited with respect to the specific details of neuropathology and microstructural architecture. In this study we used ultrahigh-b radial-DWI (UHb-rDWI) with b-values ranging from 0 to ∼7500 s/mm2 and calculated decay constant (DH ) at the high b-values, which gives much deeper insight about the microscopic environment of CSC white matter. ⋯ 2 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2019;49:204-211.

A system using patient-specific 3D-printed molds to spatially align in vivo MRI with ex vivo MRI and whole-mount histopathology for prostate cancer research.
Patient-specific 3D-printed molds and ex vivo MRI of the resected prostate have been two important strategies to align MRI with whole-mount histopathology (WMHP) for prostate cancer (PCa) research, but the combination of these two strategies has not been systematically evaluated. ⋯ 2 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2019;49:270-279.
