Association of Quadriceps Muscle Fat With Isometric Strength Measurements in Healthy Males Using Chemical Shift Encoding-Based Water-Fat Magnetic Resonance Imaging
Magnetic resonance-based assessment of quadriceps muscle fat has been proposed as surrogate marker in sarcopenia, osteoarthritis, and neuromuscular disorders. We presently investigated the association of quadriceps muscle fat with isometric strength measurements in healthy males using chemical shift encoding-based water-fat magnetic resonance imaging. Intermuscular adipose tissue fraction and i...
متن کاملReduced chemical shift-induced phase errors at 3T using novel PC-MRI encoding gradients
Background Cardiovascular MRI benefits from improved SNR-efficiency at ≥3T [1,]2, but is subject to other sources of error, which require careful consideration when transitioning from primary use of 1.5T scanners. For example, chemical shift-induced PC-MRI errors [3] are increased at 3T compared to 1.5T. Chemical shift causes the complex perivascular fat signal to chemically shift into the vess...

متن کاملMRI of Residual Red Bone Marrow in the Distal Femur of Healthy Subjects
BACKROUND The purpose of our study is to examine the correlation of the residual red bone marrow areas of distal femoral metaphysis with the age, gender, weight and hemoglobin (hgb) values; evaluate the results, and comprehend the importance of these residual areas in the light of the results. MATERIAL/METHODS 140 nonsmoking patients between the ages of 26 and 72 (92 women, 48 men) who had kn...
متن کاملChemical shift-based water/fat separation: comparison of fitting models
INTRODUCTION Quantitative water/fat separation in MRI requires careful modeling of the acquired signal. Multiple signal models have been proposed in recent years, but their relative performance has not yet been established. This abstract presents a comparative study of 12 signal models for water/fat separation. The models were selected according to three criteria: magnitude or complex fitting [...
