Quality assurance in magnetic resonance spectroscopy system

Nuclear Magnetic Resonance Spectroscopic clinical evaluation of metabolic changes in the human body has distinct advantages over Magnetic Resonance Imaging (MRI), CT and Nuclear Medicine, as it allows early detection of disease and monitoring of therapeutic processes through repeated procedures. To ensure reliable and reproducible results for spectroscopic examinations, the quality of MRS system should be controlled. Apart from the instrumental contribution in spectroscopic examinations, there are number of other variables such as tissue state and patient motion, severely affecting the image quality. The subject and instrumental contributions to the spectrum are closely related in MRS than in rest of medical imaging. Instrumental contribution in the quality of spectrum has been measured and presented
