BACKGROUND AND PURPOSE Previous T2 relaxometry studies have provided evidence for regional brain iron deficiency in patients with restless legs syndrome (RLS). Measurement of the iron content in several brain regions, and in particular the substantia nigra (SN), in early- and late-onset RLS patients using T2 relaxometry have yielded inconsistent results. In this study the regional iron content ...
The H NMR relaxometry in combination with water proton spin–spin relaxation time measurements and rheometry have been applied to study the ionic gelation of 1% w/w aqueous low methoxyl pectin solution induced by divalent Ca cations from a calcium chloride solution. The model-free approach to the analysis of H NMR relaxometry data has been used to separate the information on the static (β) and d...
BACKGROUND Beta-thalassemia major (β-TM) patients need blood transfusions, which result in iron deposition. To regulate chelation therapy, iron load has to be measured. With MRI, the amount of signal loss and T2* decay time shortening are used for iron quantification. OBJECTIVES The aim was to measure adrenal iron load with T2* relaxometry using MRI, and to compare it with liver and cardiac i...
