ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the changes of phosphorus metabolites in leukemic infiltration of liver (LIL) with two-dimensional chemical shift imaging(2D CSI)(31)phosphorus MR spectroscopy ((31)P MRS).</p><p><b>METHODS</b>Fifteen patients with LIL and 12 healthy subjects (control group) were scanned with liver 2D CSI(31)P MRS by a 1.5T MR Scanner(Sonata, Siemens Corporation). Relative quantification of phosphorus metabolites including phosphomonoesters (PME), inorganic phosphate (Pi), phosphodiesters (PDE) and beta-adenosine- triphosphate (beta-ATP) were detected and after calibrated with model factor, the ratios of PME/PDE, PME/(PME+PDE), PME/ATP, PDE/ATP and Pi/ATP were analyzed.</p><p><b>RESULTS</b>Compared with control group, the PME value, PME/PDE ratio, PME/(PME+PDE) ratio and PME/ATP ratio were increased in LIL group (1.992 +/-0.876 Compared with 1.167 +/-0.427, P <0.05), (0.551 +/-0.339 Compared with 0.254 +/-0.059,P <0.01), (0.326 +/-0.13 Compared with 0.199 +/-0.049, P <0.01)and (1.402 +/-0.654 Compared with 0.792 +/-0.232, P <0.01) respectively.</p><p><b>CONCLUSION</b>(31)P MRS examination can be used as a non-invasive procedure to evaluate the changes of phosphorus metabolites of leukemic infiltration of liver. The increase of PME value and its ratios to PDE, ATP and PME+PDE may indicate leukemic infiltration of liver.</p>
