Article Synopsis
- This study explores the connection between white matter hyperintensities (WMHs), mild traumatic brain injury (mTBI), age, and cognitive performance in a group of combat-exposed Veterans and Service Members.
- The research involved 1,011 participants, revealing that both groups had similar rates of WMHs; however, older individuals with mTBI showed a higher count of WMHs compared to those without.
- Significant relationships were found linking increased WMHs with cognitive impairments in memory and processing speed, suggesting the need for further investigation on the long-term effects of WMHs in mTBI cases.
Article Synopsis
- The study aimed to assess whether mild traumatic brain injury (mTBI) is linked to accelerated brain aging in US military personnel and Veterans.
- A total of 822 participants underwent MRI scans, with follow-up scans for some, and various cognitive and psychological tests were conducted.
- Results showed that males with deployment-related mTBI exhibited advanced brain aging, with additional factors like PTSD and depression severity contributing to this acceleration.
Article Synopsis
- * A new imaging technique, quantitative chemical exchange saturation transfer (qCEST) MRI, was developed to measure pH levels as a potential biomarker for disc-related pain.
- * A study with 25 chronic LBP patients found that the qCEST signal in painful discs was significantly higher than in non-painful ones, suggesting that qCEST could aid in diagnosing discogenic pain alongside traditional T2-weighted MRI scans.
Oncogenic GOPC-ROS1 Fusion Identified in a Congenital Glioblastoma Case.

November 2020
Congenital glioblastoma (GBM) is a rare brain tumor of infancy. While histologically they resemble pediatric and adult GBM, growing evidence suggests a distinct molecular profile. We report the case of a 7-day-old infant female with congenital GBM found to harbor a GOPC-ROS1 fusion.

These inherent tissue properties allow synthesis of various imaging sequences from a single acquisition. Clinical use of synthetic MR imaging has been described in adult populations.

In adults, this technique has been shown to increase clinician confidence in identification of diffusion restricting lesions.
Purpose: In this study, we evaluate the image quality and diagnostic confidence of the rFOV DWI technique in pediatric spine MRI.
Computed tomography (CT) is often the primary imaging modality for the evaluation of sinonasal disease. For some indications, magnetic resonance imaging (MRI) may provide additional information. There are established indications for using MRI in complicated sinonasal inflammatory disease, invasive fungal sinus disease, and sinonasal mass lesions.

Due to anatomical proximity, craniofacial trauma often involves concomitant injury to the eye and orbit. These injuries may have devastating consequences to vision, ocular motility, and cosmesis.

It is now beginning to reach a level of consistency, and its benefits are being realized in clinical practice. Comparisons between paper and digital documentation have been conducted in various specialties.

Methods: Twenty patients with keratoconus who were wearing rigid contact lenses were refitted into the Rose K lenses. Visual acuity measurements were taken with habitual lenses at the baseline visit and with the Rose K lenses at the completion of the study.
