Purpose: The major obstacles of radiofrequency ablation (RFA) heat treatments are
nonuniform heating in the thermal lesion and heat sinks caused by large blood vessels …

The influences of blood vessels and focused location on temperature distribution during
high-intensity focused ultrasound (HIFU) ablation of liver tumors are studied numerically. A …

Background: Sonography is a valuable tool in the assessment of porto-systemic pathologies.
This study aimed at determining the mean portal vein diameter based on age, gender and …

Background and objectives The liver, a vital metabolic organ, is always susceptible to
various diseases that ultimately lead to fibrosis, cirrhosis, acute liver failure, chronic liver …

The diameter of portal vein is variable according to gender, age, weight, height, body mass
index (BMI) and with factors like, respiration, postural changes and absorptive state …

Background: Ultrasonographic (USG) measurements of the liver length, gallbladder wall
thickness (GBWT), diameters of the inferior vena cava (IVC), portal vein (PV), and pancreas …

Introduction: The portal vein (PVD) diameter is one of the predictive variables of portal
hypertension. This diameter can differ according to the population. The objective of this …

Devices, systems and methods are described for visualizing the anatomy of a patient. An
expanding portion is configured to expand towards the tissue walls of a body space and be …

Background: There are many causes of the portal vein (PV) disease and these include portal
hypertension (PHT), PV thrombosis, PV gas and PV stenosis/obstruction. PHT is a common …

Background: The portal vein is one of the main sources of blood supply of the liver. About
three quarters of the liver blood flow is from the portal vein. Objectives: To assess the mean …
