![]() ![]() This was related to systematic differences in the intensity of cerebrospinal fluid (CSF), with higher intensities for CSF located in the ventricles compared with CSF in the cisterns, at 3T versus 1.5T, which could not be removed with three different applied bias correction algorithms. ![]() We found systematic differences in ICV estimation, tested in a cohort of healthy subjects ( n = 5) that had been imaged using 1.5T and 3T scanners, and confirmed in two independent cohorts. As population-based studies may obtain images from scanners with different field strengths, a method to normalize regional brain volumes according to intracranial volume (ICV) independent of field strength is needed. ![]()
