Computed Tomography Angiography Compared with Computed Tomography Perfusion in the Diagnosis of Cerebral Vasospasm: A Systematic Review and Meta-Analysis.

Introduction: Cerebral vasospasm (CV) is a serious complication after subarachnoid hemorrhage; however, swift identification can be challenging. Computed tomography perfusion (CTP) directly measures tissue perfusion and may better screen for CV compared with other modalities. This systematic review summarizes studies assessing the diagnostic performance of computed tomography angiography (CTA) and CTP in identifying CV.

Comparison of Magnetically Controlled Growing Rods with Other Distraction-Based Surgical Technologies for Early-Onset Scoliosis: A Systematic Review and Meta-Analysis.

Background: Severe and progressive early-onset scoliosis (EOS) has a serious prognosis including cardiopulmonary compromise. Growth-friendly technologies are the current surgical standard of care. Magnetically controlled growing rods (MCGRs) are newer implants with the potential for better quality of life and cost savings; however, they have not been well compared with the traditional distraction-based implants.
