Human Eye Magnetic Resonance Imaging Relaxometry in Diabetic Retinopathy
Two quantitative ocular magnetic resonance imaging (MRI) methods for the clinical use in Ophthalmology and Radiology were developed. Ocular MRI images with spatio-temporal resoultions of 0.78/1.56/2/(5 to 84) mm/mm/mm/s were acquired from patients with diabetic retinopathy and normal subjects using a 1 T MRI system. T1 and T2 MRI relaxometry maps were generated offline from the MRI images acqui...
متن کاملVasodilator response assessment in porcine myocardium with magnetic resonance relaxometry.
BACKGROUND This research describes an early preclinical study of the biophysical mechanisms governing changes in myocardial T2 during vasodilation in normal myocardium. METHODS AND RESULTS Theoretical modeling and experimental studies in an instrumented pig model (n=7) provided measures of changes in myocardial T2, relative blood volume (BV), and microcirculation oxygen levels (%O2) during in...
متن کاملProton Nuclear Magnetic Resonance (NMR) Relaxometry in Soil Science Applications
Proton NMR relaxometry is a very powerful tool for investigating porous media and their interaction with water or other liquids and the mobility and interaction of organic molecules in solution. It is commonly used in material science or earth science. However, it is only scarcely applied in soil science although it shows great potential for helping to understand water uptake into the soil matr...
متن کاملTwo-phase Flow Measurements by Nuclear Magnetic Resonance (nmr)
We pioneered NMR studies of concentrated suspensions starting in the late 1980’s (Majors, et al., 1989; Altobelli, et al., 1991; Abbott, et al., 1991). In those studies, we measured concentration and velocity of the liquid component in either in pipe or Couette flow. If we compare these early studies of suspensions with more recent ones (Hampton, et al., 1997), imaging time has gone from 40 min...
