Considering the key role of liver in body metabolism, the study of bile composition is of great importance. In vitro ¹H MRS of bile samples have shown diagnostic value in detecting various hepatopancreatobiliary disorders. Given the invasive nature of this procedure, we considered the possibility of gathering in vivo data. We present here our initial efforts to obtain bile spectra from pigs using a 3T clinical scanner comparing the use of a Siemens body array coil with an optimized home-built receive array coil.
