Estimating Blood Flow Velocity in Liver Vessels
Orthogonal polarization spectroscopy (OPS) is a technique for taking images to finally characterise microcirculation. Current image analysis algorithms have limitations when applied to image sequences obtained from the liver. We developed an automatic analysis tool which enables detection of liver vessels, measurement of vessel diameters, and determination of blood flow velocities with sparse u...
متن کاملMeasurement of Liver Blood Flow: A Review
The study of hepatic haemodynamics is of importance in understanding both hepatic physiology and disease processes as well as assessing the effects of portosystemic shunting and liver transplantation. The liver has the most complicated circulation of any organ and many physiological and pathological processes can affect it. This review surveys the methods available for assessing liver blood flo...
متن کاملRenal blood flow in malignant disease of the liver.
Although functional renal failure has been reported in patients with malignant disease of the liver, renal haemodynamics and function have not been investigated. Renal and intrarenal blood flow was measured using the (133)Xenon washout technique and creatinine clearances by the standard method in 14 patients with a variety of primary and secondary tumours of the liver in the absence of cirrhosi...
متن کاملPortal blood flow in cirrhosis of the liver.
Direct measurements of portal flow and pressure in a relatively large number of patients with cirrhosis show a marked reduction in flow associated with a nearly constant plateau of portal pressure. This lack of correlation indicates the complex relationships of resistances in the splanchnic, collateral, and hepatic circuits determining the division of the available splanchnic flow between the p...
متن کاملSignificance of blood flow measurement in clinical liver transplantation.
VASCULAR complications are not uncommon after orthotopic liver transplantation (OL Tx).'-2 In order to further improve the outcome of OL Tx, intraand postoperative adjunctive measures will be required to further improve such problems as hepatic artery thrombosis. Since the first successful measurement in 1945 by Bradley and others l with a dye clearance method using bromosulphthalein, various m...
