As advances are made in quantitative magnetic resonance imaging, specifically diffusion tensor imaging, researchers have investigated its potential to serve as a biomarker of disease or prognosticator for postoperative recovery in the management of cervical spondylotic myelopathy. Here, we narratively review the current state of the emerging literature, describing areas of consensus and disagreement. ⋯ Preoperative fractional anisotropy most frequently and best correlates with functional outcomes following surgery for cervical spondylotic myelopathy, according to a review of the current literature. The findings were not universal and at times contradictory, highlighting the need for high-quality future investigations to better define the utility of diffusion tensor imaging in spinal disease.

The most widely adopted materials for interbody fusion implants are titanium and polyetheretherketone (PEEK), both of which have their potential advantages and disadvantages. Despite the differences between PEEK and titanium, there is no consensus on which material provides better clinical and radiological outcomes. Therefore, the purpose of this meta-analysis is to analyze the clinical and radiographic outcomes between the two cages. ⋯ In the lumbar spine, titanium cages were shown to have a lower rate of subsidence and revision compared to PEEK. As for the cervical spine, the difference between cages did not reach statistical significance in any of the analyzed outcomes.

Brain metastases (BMs) are the most frequent tumors of the central nervous system. Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that provides insights into brain microstructural alterations and tensor metrics and generates tractography to visualize white matter fiber tracts based on diffusion directionality. This systematic review assessed evidence from DTI biomarker alterations in BMs and comparable tumors such as glioblastoma. ⋯ DTI metrics provide noninvasive biomarkers for distinguishing BMs from other tumors and predicting outcomes. Key metrics included peritumoral FA and mean diffusivity.

Françoise LAPIERRE, Bernadette STILHART, The First Two Female Big Bosses in French Neurosurgery.
We believe it is crucial to discuss the roles of women in medicine, specifically in surgery and neurosurgery. Despite society's progress toward gender equality in surgery and neurosurgery, these fields remain predominantly male. Recognizing and supporting these talented women allow them to bring attention to their contributions in their respective fields. ⋯ She also served as the Editor-in-Chief of the journal Neurochirurgie for several years. Bernadette Stilhart, with a career spanning almost 50 years, has trained multiple generations of neurosurgeons from France and around the world. She has also been the head of one of France's oldest neurosurgery departments in Colmar, Alsace for 20 years.

To study associations of clinical characteristics and treatment choice with functional outcome, mortality, and time to death in a national sample of aneurysmal subarachnoidal hemorrhage patients. ⋯ The patient selection in Sweden after aneurysmal subarachnoidal hemorrhage showed similar values for dGOSE, 1-year mortality, and survival probability between patients treated with microsurgery or endovascular technique. Poor dWFNS, higher age, and DIND were significantly associated with unfavorable dGOSE, mortality, and survival probability. Pupil dilatation was significantly associated with mortality and survival probability.
