Spectral Doppler Metric Spots Hepatic Arterial Stenosis

By Erik L. Ridley, AuntMinnie staff writer
March 31, 2017 -- A new quantitative spectral Doppler ultrasound measurement can accurately detect liver transplant hepatic arterial stenosis, offering the potential of reducing the number of unnecessary angiography procedures in these patients, according to research published in the April issue of the Journal of Ultrasound in Medicine.

In a retrospective review of 69 patients who had suspected transplant hepatic arterial stenosis, a team of researchers found that the stenosis index -- a new measure that accounts for the entire spectral Doppler waveform -- was more accurate than traditional quantitative ultrasound metrics for detecting cases of clinically significant stenosis.
