Researchers from the University of Waterloo and the University of Toronto are collaborating to better understand how glioblastoma multiforme (GBM) advances when it is not treated.

New research discourages use of advanced vascular imaging in trauma patients

Experts argue that the overall incidence of blunt cerebrovascular injury is very low and that symptomatic vascular injuries in these cases are even lower. 

Hospitals efficiently share resources and expertise across French/Belgian border by digitizing pathology with Sectra

Linköping, Sweden – January 12, 2023 – International medical imaging IT and cybersecurity company Sectra (STO: SECT B) has signed a digital pathology contract with the public hospitals in Roubaix and Mouscron. The two hospitals, situated on either side of the French/Belgian border, will utilize a joint Sectra digital pathology solution to enhance their collaboration. The tools provided in the digital workflow will also help reduce variation between pathology reviews and increase efficiency in diagnostics, all for the benefit of the patients in this region.

Subtraction boosts CCTA accuracy, even in the presence of extensive calcium

(b) In CPR image after subtraction, mild stenosis (< 50%) is depicted (arrow). (c) No significant stenosis (< 50%) is observed in ICA (arrow). Image courtesy of Academic Radiology.

Researchers recently found results yielded via subtraction CCTA to be similar to those produced by ICA in assessing stenosis grading.
