Whole Liver 31P Metabolite Mapping with 3D CSI
نویسندگان
چکیده
Introduction It has been shown that 3D P CSI sequences can be used to enhance spatial coil coverage of the single-channel coil to aquire 3D P spectrscopic data [1]. Furthermore, multi-channel P phased-array coils can be used to acquire data from the entire abdominal slice using a 2D CSI sequence [2]. If the coil is large enough to wrap around the entire liver, 3D MR spectroscpic data can also be aquired for the entire liver by combining these two methods. However, lack of such coils and long scan times (long TR and large averages) for P spectroscopy have prevented the acquition of such data in the past. In this abstarct we present P in-vivo MRSI data collected from the entire liver using a 3D CSI sequence, allowing for whole liver metabolite mapping for the first time.

Human Cardiac 31P-MR Spectroscopy at 3 Tesla Cannot Detect Failing Myocardial Energy Homeostasis during Exercise
Phosphorus-31 magnetic resonance spectroscopy (31P-MRS) is a unique non-invasive imaging modality for probing in vivo high-energy phosphate metabolism in the human heart. We investigated whether current 31P-MRS methodology would allow for clinical applications to detect exercise-induced changes in (patho-)physiological myocardial energy metabolism. Hereto, measurement variability and repeatabil...

In addition to direct assessment of high energy phosphorus containing metabolite content within tissues, phosphorus magnetic resonance spectroscopy (31P-MRS) provides options to measure phospholipid metabolites and cellular pH, as well as the kinetics of chemical reactions of energy metabolism in vivo. Even though the great potential of 31P-MR was recognized over 30 years ago, modern MR systems...

We aimed to determine the metabolic profile and effects of chemotherapy on ovarian cancer cell metabolism in a three-dimensional (3D) vs. a two-dimensional (2D) construct using 31P-magnetic resonance spectroscopy (MRS). Three ovarian cancer cell lines were embedded in a 3D perfused Matrigel construct or grown in a 2D monolayer. Metabolic differenc...

PURPOSE Absolute concentrations of high-energy phosphorus (31P) metabolites in liver provide more important insight into physiologic status of liver disease compared to resonance integral ratios. A simple method for measuring absolute concentrations of 31P metabolites in human liver is described. The approach uses surface spoiling inhomogeneous magnetic field gradient to select signal from live...
متن کاملComparison of three reference methods for the measurement of intracellular pH using 31P MRS in healthy volunteers and patients with lymphoma
31P magnetic resonance spectroscopy (31P MRS) can measure intracellular pH (pHi) using the chemical shift difference between pH-dependent inorganic phosphate (Pi) and a pH-independent reference peak. This study compared three different frequency reference peaks [phosphocreatine (PCr), α resonance of adenosine triphosphate (αATP) and water (using 1H MRS)] in a cohort of 10 volunteers and eight p...
