The duplex Doppler ultrasound indices, including the mean portal vein velocity, splenic index (SI) and splenoportal index (SPI) were evaluated to determine the statistical correlation with shear wave velocity (SWV) of ARFI. We also analysed the differences in the correlations between the SI, SPI and SWV of the group who had varices. The correlations were assessed with Spearman\u2032s rank correlation coefficients.<\/jats:p>\n               <jats:p>Results There was an increase of SWV in parallel with the increase of the SI (\u03c1=0.409, p&amp;lt;0.01) and SPI (\u03c1=0.451, p&amp;lt;0.01). In the patient group who did not have varices (n=74), the Doppler indices were found to be more correlated with the SWV (SI: \u03c1=0.447, SPI: \u03c1=0.552, p&amp;lt;0.01). However, the group with varices showed no correlation between the SWV and the Doppler parameters.<\/jats:p>\n               <jats:p>Conclusion SWV of ARFI was well correlated statistically with Doppler parameters, but is of limited value in predicting portal hypertension directly owing to great variability of Doppler parameters. By evaluating the correlation between ARFI and Doppler ultrasound, we suggest that the SWV might be a non-invasive supplementary tool for predicting portal hypertension.<\/jats:p>","DOI":"10.1259\/bjr\/74648924","type":"journal-article","created":{"date-parts":[[2012,7,19]],"date-time":"2012-07-19T12:55:05Z","timestamp":1342702505000},"page":"e404-e409","source":"Crossref","is-referenced-by-count":10,"title":["Predicting portal hypertension as assessed by acoustic radiation force impulse: correlations with the Doppler ultrasound"],"prefix":"10.1093","volume":"85","author":[{"given":"J-Y","family":"Han","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J H","family":"Cho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H J","family":"Kwon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K J","family":"Nam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2014,3,5]]},"reference":[{"key":"2024050213360966100_b1","doi-asserted-by":"crossref","first-page":"574","DOI":"10.1148\/radiol.2402051142","article-title":"Recent variceal bleeding: Doppler US hepatic vein waveform in assessment of severity of portal hypertension and vasoactive drug response.","volume":"240","author":"Baik","year":"2006","journal-title":"Radiology"},{"key":"2024050213360966100_b2","doi-asserted-by":"crossref","first-page":"1103","DOI":"10.1111\/j.1478-3231.2007.01526.x","article-title":"Damping index of Doppler hepatic vein waveform to assess the severity of portal hypertension and response to propranolol in liver cirrhosis: a prospective nonrandomized study.","volume":"27","author":"Kim","year":"2007","journal-title":"Liver Int"},{"key":"2024050213360966100_b3","doi-asserted-by":"crossref","first-page":"1159","DOI":"10.1111\/j.1572-0241.2008.01826.x","article-title":"Noninvasive prediction of clinically significant portal hypertension and esophageal varices in patients with compensated liver cirrhosis.","volume":"103","author":"Berzigotti","year":"2008","journal-title":"Am J Gastroenterol"},{"key":"2024050213360966100_b4","doi-asserted-by":"crossref","first-page":"132","DOI":"10.1148\/radiol.2481071257","article-title":"Esophageal varices: Noninvasive diagnosis with Duplex Doppler US in patients with compensated cirrhosis.","volume":"248","author":"Liu","year":"2008","journal-title":"Radiology"},{"key":"2024050213360966100_b5","doi-asserted-by":"crossref","first-page":"595","DOI":"10.1148\/radiol.2523081928","article-title":"Liver fibrosis in viral hepatitis: noninvasive assessment with acoustic radiation force impulse imaging versus transient elastography.","volume":"252","author":"Friedrich-Rust","year":"2009","journal-title":"Radiology"},{"key":"2024050213360966100_b6","doi-asserted-by":"crossref","first-page":"538","DOI":"10.1111\/j.1478-3231.2009.02130.x","article-title":"Evaluation of acoustic radiation force impulse elastography for fibrosis staging of chronic liver disease: a pilot study.","volume":"30","author":"Takahashi","year":"2010","journal-title":"Liver Int"},{"key":"2024050213360966100_b7","first-page":"303","article-title":"Performance of a new elastographic method (ARFI technology) compared to unidimensional transient elastography in the noninvasive assessment of chronic hepatitis C.
