The Application of Fat-Suppression MR Pulse Sequence in the Diagnosis of Bone-Joint Disease
نویسندگان
چکیده
Fat-suppression technology of magnetic resonance is very important in clinical practice. This article is written to interpret the principle, advantages/disadvantages and clinical applications of some regular fat-suppression sequences in the diagnosis of Bone-Joint Disease, including: 1) frequency-selective saturation (FS); 2) short-TI inversion recovery (STIR); 3) frequency selective inversion pulse; 4) fat suppression water or fat selective excitation technique; 5) Dixon technology and 6) magnetization transfer contrast (MTI).

The Optimization of Magnetic Resonance Imaging Pulse Sequences in Order to Better Detection of Multiple Sclerosis Plaques
Background and objective: Magnetic resonance imaging (MRI) is the most sensitive technique to detect multiple sclerosis (MS) plaques in central nervous system. In some cases, the patients who were suspected to MS, Whereas MRI images are normal, but whether patients don’t have MS plaques or MRI images are not enough optimized enough in order to show MS plaques? The aim of the current study is ...
متن کاملNon-invasive quantification of liver fat content by different Gradient Echo MRI sequences in patients with Non-Alcoholic Fatty Liver Disease (NAFLD)
Introduction: Non-invasive quantification of liver fat by Gradient echo (GRE) Technique is an interesting issue in quantitative MRI. Despite the numerous advantages of this technique, fat measurement maybe biased by confounding and effects. The aim of this study was to evaluate the GRE pulse sequences with different and weighting for liver fat quantification in patients with...
