The Reproducibility of 31-Phosphorus MRS Measures of Muscle Energetics at 3 Tesla in Trained Men
OBJECTIVE Magnetic resonance spectroscopy (MRS) provides an exceptional opportunity for the study of in vivo metabolism. MRS is widely used to measure phosphorus metabolites in trained muscle, although there are no published data regarding its reproducibility in this specialized cohort. Thus, the aim of this study was to assess the reproducibility of (31)P-MRS in trained skeletal muscle. METH...
متن کاملDilated Cardiomyopathy: Phosphorus 31 MR Spectroscopy at 7 T
Purpose To test whether the increased signal-to-noise ratio of phosphorus 31 (31P) magnetic resonance (MR) spectroscopy at 7 T improves precision in cardiac metabolite quantification in patients with dilated cardiomyopathy (DCM) compared with that at 3 T. Materials and Methods Ethical approval was obtained, and participants provided written informe consent. In a prospective study, 31P MR spectr...
متن کاملP MRS of human brain tumors at 3 T using 1 H – 31 P polarization transfer
Introduction: It is well known that tumors have an abnormal phospolipid metabolism[1]. This is typically reflected in the higher phosphomonoester and total choline compound levels observed by in vivo P and H MRS respectively, which may be used as biomarkers for diagnosis and treatment evaluation [1,2,3,4]. For practical and sensitivity reasons H MRS has been used most extensively in the clinic ...
متن کاملDiagnosis of rejection after liver transplantation: use of phosphorus-31 magnetic resonance spectroscopy ((31)P-MRS).
BACKGROUND In vivo hepatic phosphorus-31 magnetic resonance spectroscopy (31)P-MRS) provides non-invasive information about phospholipid metabolism. AIMS To delineate (31)P-MRS abnormalities in patients with chronic rejection and to characterize spectral changes by pathology. PATIENTS AND METHODS Sixty-six liver transplant recipients (18 with chronic rejection and 48 with normal graft funct...
متن کاملDetection and Alterations of Acetylcarnitine in Human Skeletal Muscles by 1H MRS at 7 T
OBJECTIVES The aims of this study were to detect the acetylcarnitine resonance line at 2.13 ppm in the human vastus lateralis and soleus muscles, assess T1 and T2 relaxation times, and investigate the diurnal and exercise-related changes in absolute concentration noninvasively, using proton magnetic resonance spectroscopy at 7 T. MATERIALS AND METHODS All measurements were performed on a 7 T ...
