Abstract:
Objective To evaluate the value of furosemide in magnetic resonance urography(MRU) with low field magnet.Methods The routine MRU and MRU after administration of intravein of furosemide were performed with heavily T_2 weighted fast spin echo pulse sequence in 32 cases with urethral diseases.Then three-dimensional(3D) reconstruction for post procedure processing with a maximum-intensity projection(MIP)algorithm was done.Results On routine MRU,there were no image of collecting systems of kidney in 5 cases,and poor images of parenchyma and collecting systems of kidney in 18 cases after using furosemide before MRU,MRU provided high resolution images of parenchyma and collecting systems of kidney in all cases,and images were much clear,the localized diagnosis was accurate.Conclusion MRU using furosemide before scanning can display the parenchyma and collecting systems of kidney distinctively,so furosemide can be regarded as a routine method used before MRU with low field magnet.
