BACKGROUND AND PURPOSE Perfusion-weighted (PW) MRI is increasingly used to identify the tissue at risk. The adequate PW-MRI map and threshold remain controversial due to a considerable individual variation of values. By comparative positron emission tomography, we evaluated a simple MR-based and positron emission tomography-validated calibration of PW maps. METHODS PW-MRI and quantitative positron emission tomography (15O-water) of patients with acute stroke were used to calculate averaged as… CONTINUE READING
