As a rare but serious complication after carotid artery revascularization, cerebral hyperperfusion syndrome (CHS) is one of the important causes of postoperative hemorrhagic stroke
Arterial spin labeling (ASL) is a non-invasive MR technique that images cerebral perfusion by using magnetically labeled arterial blood as an endogenous tracer
Based on the existence of ATAs, Zaharchuk et al.
Recently, a study published in European Radiology evaluated the value of this ATA-based ASL score in predicting cerebral hyperperfusion after CEA in patients with carotid artery stenosis, providing a valuable non-invasive method for clinical preoperative prediction of cerebral hyperperfusion after CEA.
This study included consecutive patients with carotid artery stenosis who underwent CEA between May 2015 and July 2021
Of the 86 patients included, 17 (19.
This study demonstrates that ATA on ASL MRI is a clinically valuable imaging marker that can be obtained by visual inspection without complex post-processing steps
