Abstract:
OBJECTIVETo analyze the value of dynamic contrast-enhanced magnetic resonance imaging (CEMRI) for evaluating diffuse tumor infiltration of bone marrow in patients with acute leukemia (AL).
METHODSFrom January 2010 to February 2016, 80 AL patients admitted in our hospital were chosen as AL patient group, 100 healthy people were chosen as control group, and all subjects were diagnosed with MRI and CEMRI. The Emax and Slope of ilium and vertebra lumbalis were compared between AI patient and control groups. The relation of Emax and Slope with protocells % was analyzed.
RESULTSThe Emax and Slope of AL patients were significantly higher than those of control group (P<0.05). After treatment, the Emax and Slope of CR/PR patients decreased significantly (P<0.05). Multiple regression analysis showed that the protocells %=-0.5632+0.0540 Emax+0.0056 Slope. The Emax and Slope of AL patients had significant correlation with Protocells %(P<0.05).
CONCLUSIONThe results of CEMRI relate with pathological examination and treatment effect.
