## Objectives/hypothesis: Determine the role of mastoid volume in middle ear pressure (mep) regulation. the hypothesis was that inert gas exchange between blood and middle ear (me) is slower for larger mastoid volumes. ## Study design: Prospective. ## Methods: For 21 enrolled subjects, the bila
This work addresses the fundamental limits imposed by the MRI process on the accuracy with which vessel diameters and cross-sectional areas can be derived from time-of-flight (TOF) and phase-contrast (PC) MR source images. By means of simulations and in vitro experiments, it is demonstrated that, ev
