Quantification of Fatty Acid Compositions Using MR-imaging and Spectroscopy at 3 T
Introduction Multi-echo imaging has previously been used for fat/water separation and fat quantification [1,2]. The same technique may potentially also be able to differentiate different fat types depending on the amount of unsaturated fatty acids. The fatty acid composition of adipose tissue is not only dependent on the diet, but may also be interesting in e.g. chronic inflammations [3]. Also,...
متن کاملHepatic Iron Quantification on 3 Tesla (3 T) Magnetic Resonance (MR): Technical Challenges and Solutions
MR has become a reliable and noninvasive method of hepatic iron quantification. Currently, most of the hepatic iron quantification is performed on 1.5 T MR, and the biopsy measurements have been paired with R 2 and R 2* values for 1.5 T MR. As the use of 3 T MR scanners is steadily increasing in clinical practice, it has become important to evaluate the practicality of calculating iron burden a...
متن کاملAbsolute Quantification of Human Brain Metabolites in Gulf War Syndrome Using Proton MR Spectroscopy at 3T
Introduction Gulf War Syndrome (GWS) is an illness reported by combat veterans of the 1991 Persian Gulf War typified by wide-ranging symptoms including chronic fatigue, loss of muscle control, headaches, dizziness and loss of balance, memory problems, muscle and joint pain, indigestion, skin problems, shortness of breath, and insulin resistance. Three distinct GW syndromes have been identified:...
متن کاملCorrelation between choline level measured by proton MR spectroscopy and Ki-67 labeling index in gliomas.
BACKGROUND AND PURPOSE The clinical relevance of proton MR spectroscopy needs further clarification as to its usefulness and limitations. The purpose of this study was to investigate the correlation between the semiquantitative choline-containing compound level (Cho value) measured by MR spectroscopy and the Ki-67 labeling index in gliomas. METHODS Localized proton spectra were obtained in 26...
متن کاملProton MR Spectroscopy
Nuclear magnetic resonance spectroscopy (MRS) has been in use in biochemistry labs for more than 50 yr. In its earlier years, it was used primarily for in vitro chemical analysis of small samples. Magnetic resonance imaging (MRI) is a powerful imaging technique that combines exquisite sensitivity to soft tissue contrast with the ability to demonstrate anatomy in many different planes and projec...
