The aim of this study was to evaluate the interobserver variability during duplex ultrasonographic investigation of the SMA. Eleven healthy volunteers were examined twice under the same conditions by two independent observers. Three basic Doppler wave parameters were assessed for the SMA: pV, edV, and rT. The tD was recorded for SMA and abdominal aorta (AotD) with B-mode imaging. The interobserver variability was very low for all parameters: pV = 13.5 cm/s; edV = 3.4 cm/s; rT = 0.01 s; tD = 0.3 mm; AotD = 0.5 mm, with corresponding 95% confidence intervals as follows: pV = 19 cm/s; edV = 4.7 cm/s; rT = 0.015 s; tD = 0.4 mm; and AotD = 0.75 mm. Coefficients of variation also showed very low dispersion for results obtained. Under the appropriate standard conditions for duplex sonographic examination of the mesenteric artery, assessments of basic Doppler wave parameters do not differ significantly between independent investigators. Reliable evaluation of B-mode distances can be obtained by replication of measurements.
