Cryoporometry and relaxometry of water in silica-gels
Magnetic Resonance Imaging, 2001Both cryoporometry and relaxometry are tools to determine the pore size distribution (PSD) of a porous material with NMR. The melting point depression is described by the Gibbs-Thomson equation, yielding the PSD from cryoporometry. The enhanced relaxivity is caused by the surface of the porous material, yielding the PSD from relaxometry.

Muskelrelaxanzien und Relaxometrie
2017Seit ihrer Einfuhrung in die klinische Praxis in den 1940er Jahren haben Muskelrelaxanzien einen festen Platz im Rahmen sog. balancierter Anasthesiekonzepte. Durch die pharmakologische Muskelerschlaffung werden chirurgische Eingriffe wesentlich erleichtert oder erst moglich gemacht.

Transverse relaxometry with stimulated echo compensation
Magnetic Resonance in Medicine, 2010AbstractPresented is a fitting model for transverse relaxometry data acquired with the multiple‐refocused spin‐echo sequence. The proposed model, requiring no additional data input or pulse sequence modifications, compensates for imperfections in the transmit field and radiofrequency (RF) profiles.

T2 Relaxometry of Human Median Nerve
Seminars in Musculoskeletal Radiology, 2009This article examines the T2 relaxation characteristics of the median nerve. Knowledge of the T2 relaxation time is essential to optimize clinical magnetic resonance imaging (MRI) protocols and to enhance the visibility of pathophysiological changes in tissues. The T2 relaxation time of the median nerve is short relative to the T2 of other tissues like

Relaxation times and diffusion coefficients can be measured in inhomogeneous magnetic fields by analyzing signal decay and build-up in the time domain Inhomogeneous fields are inexpensive to generate with permanent magnets The fields of permanent magnets are low (up to 2 T) compared to those of most superconducting NMR magnets (up to 24 T)

[Difficulties in the relaxometry of diabetics].
Anasthesiologie, Intensivmedizin, Notfallmedizin, Schmerztherapie : AINS, 1994Based upon clinical experience, peripheral nerve stimulation for neuromuscular monitoring under general anesthesia sometimes seems to be difficult in patients with diabetes mellitus. The aim of this study was to evaluate the applicability of the evoked electromyogram (EMG) in diabetics compared to non-diabetic controls.109 ophthalmosurgical patients ...

The main objective of field-cycling experiments [231, 367] is to obtain information on the spectral density of the fluctuating spin interactions in a frequency range as wide as possible.1 Typical examples are discussed in Chaps. 14 and 16 (see Figs. 12.1 and 14.2, for instance).
