Interobserver and interquipment variability of echo‐doppler examination of the portal vein: Effect of a cooperative training program
Carlo Sabbà, Carlo Merkel, Marco Zoli, Giovanna Ferraioli, Stefano Gaiani, David Sacerdoti, Luigi Bolondi – 1 February 1995 – The aim of this study was to assess the interobserver, interequipment, and time‐dependent variabilities of echo‐Doppler measurements of portral blood flow velocity (PBV), portal vein diameters (PVDs) and their derived parameters, portal blood flow (PBF), and congestion index (CI) in cirrhotic patients. The influence of a cooperative training program of the opeators on the reproductibility of the results was also investigated.
