Article Synopsis
- - The field of neuroanaesthesia has grown rapidly to address new challenges in patient care during neurosurgical and diagnostic procedures, leveraging advanced technology and techniques.
- - Innovations like intraoperative CT scans, MRI, and minimally invasive methods have transformed vascular neurosurgery, allowing for more complex and precise procedures.
- - Recent developments in neuroanaesthesia include the use of ketamine, opioid-free techniques, and supportive methods for intraoperative monitoring, alongside an emphasis on awake surgeries to improve patient outcomes.
Prevalence of Traumatic Findings on Routine MRI in a Large Cohort of Professional Fighters.

Background And Purpose: Previous studies investigating MR imaging abnormalities among fighters have had small sample sizes. This investigation assessed a large number of fighters using the same conventional sequences on the same scanner.
Materials And Methods: Conventional 3T MR imaging was used to assess 499 fighters (boxers, mixed martial artists, and martial artists) and 62 controls for nonspecific WM changes, cerebral microhemorrhage, cavum septum pellucidum, and cavum vergae.
Background And Purpose: Although single-voxel proton MR spectroscopy is a noninvasive method that enables measurement of brain metabolite concentrations, it has been shown that physiologic brain motion causes inaccuracies in measurement of metabolite concentrations and increases the overall SD of the measurements when the stimulated echo acquisition mode (STEAM) is used. We tested the hypothesis that the point-resolved spectroscopy (PRESS) technique is less sensitive to physiologic brain motion than the STEAM technique.
Methods: In 10 healthy subjects, spectra were obtained from a voxel located in the left basal ganglia by using the PRESS sequence with cardiac gating and without water suppression to assess global phase change as a function of physiologic brain motion.
Introduction: Isolated spinal aneurysms are rare; only a few have been reported. To the best of our knowledge, this series represents the largest experience with four ruptured spinal aneurysms, all of which were treated surgically.
Methods: Clinical information from the hospital charts and diagnostic images of four patients with the diagnosis of spinal aneurysms were reviewed from the senior authors' (RFS, JMZ) office database, surgical reports, and radiological imaging database.
Spinal artery aneurysms are usually found with arteriovenous malformations or other entities that increase hemodynamic stress. Isolated spinal artery aneurysms are rare. Four patients who presented with the acute onset of lower back pain underwent MR imaging, which revealed spinal subarachnoid hemorrhage.
