ABSTRACT
Objective To compare the safety and efficiency of non -ionic monomer diagnostic opaque, iodixanol (Visipaque) and that of non -ionic disomer diagnostic opaque, iohexol (Omnipaque). Methods By comparing retrospectively the DSA opacification of 60 patients from 2006 to 2007, patients′ indispositions, adverse reactions and pictorial efficiency were recorded respectively. Results In the control group, iodixanol showed less indisposition caused by injection than iohexol and there′ s no obvious difference of indisposition. Both images met diagnostic requirements. Conclusion Both iodixanol and iohexol are safe, efficient and well -tolerant diagnostic opaque. Iodixanol is better than iohexol in indisposition caused by injection.
ABSTRACT
Objective To evaluate the value of DSA image mosaic in arteriography in lower extremities. Methods 22 suspected cases were examined by bolus chase, and then the images were mosaiced to a full picture after processing by Paste to judge the image effects of vessels. Results This method could display the whole image by one injection of contrast media. Vary lesions were found in the 22 cases. Conclusion This method can display the lower extremities lesions directly, which is better than traditional DSA.
