Comparison of colour doppler ultrasound (CDUS) with multidetector computed tomography (MDCT) portography in evaluating portal hypertension

ABSTRACT Background Portal hypertension is a common medical problem in India. Imaging plays an important role in confirmation of the diagnosis, identification of the nature and site of obstruction with determination and prediction of potential complications. The advent of new modalities like ultrasonography, computed tomography and magnetic resonance imaging has added to the diagnostic armamentarium for non-invasive evaluation of portal hypertension. Objectives To compare diagnostic efficacy of grayscale with colour doppler ultrasound (CDUS) vis-a-vis multidetector computed tomography (MDCT) portography in the evaluation of portal hypertension Methods Forty patients with definitive clinical and laboratory diagnosis of portal hypertension were included in the study. All patients were evaluated by CDUS and MDCT portography. Results The aetiology and site of obstruction could be demonstrated in 87.5% cases. Liver parenchymal changes and nodularity were detected more often by CDUS than MDCT ( p k =1, p Conclusion CDUS and MDCT portography, when used in combination provide accurate demonstration of aetiopathogenesis, extent of disease and its complications. The findings of combined modalities correlate better with the disease process and its outcome. Copyright © 2014, Indian Journal of Medical Specialities. Published by Reed Elsevier India Pvt. Ltd.
