ABSTRACT
Objective:To evaluate the diagnostic efficacy of SPIO in known liver lesions.Methods:30 patients with known liver lesion were underwent MRI.The contrast noise rate(CNR)of lesion to liver and the relative enhancement rate(RE)of liver were measured at 10、30、45、70 min and 16 hour after SPIO was injected.The dynamic curve of signal-noise were made and analysed.Results:The study shown that the hepatic parenchyma had a significantly negative enhancement in T 2 weight of SE and GRE sequence.However,the signal intensity showed few changes in hepatic metastases and only a little positive or negative enhancement in angioma、HCC and FNH.Conclusion:SPIO,as a negative contrast media for liver,has a significantly efficacy to show liver lesions,and as liver lesion-specific contrast MR agent,is worth being explored.
