Wechsatol W, Bejan A, Lorente S. Tree-shaped flow architectures: strategies for increasing optimization speed and accuracy. Understanding the type of CT scanner used is important as scan parameters such as transit time, acquisition time, applied kVp and mAs may differ between scanners. Hepatic vein disorders can result in focal or diffuse venous obstruction. The microcirculation happens through lobules which hexagonal shape corresponds to minimum flow resistances. The sinusoids tortuous network bathes the entire lobule, supplying the blood to the central vein from the 6 sources (hepatic artery+portal vein). J Thorac Imaging 22(2):125129, Ajlan AM, Binzaqr S, Jadkarim DA, Jamjoom LG, Leipsic J (2016) High-pitch Helical dual-source computed Tomographic pulmonary angiography: comparing image quality in inspiratory breath-hold and during free breathing. Lobules of the liver paving the entire available domain. For a long time, such structures were considered as being the result of chance, i.e. The blood distribution within the lobule is similar to a reverse river basin connecting rivulets to a central sink. Pater L, Berg J. The portal vein brings blood rich in nutrients and antigens from the gastrointestinal system. http://creativecommons.org/licenses/by/4.0/. The term (g+1)3/3g is lower than 1 as soon as the generation number reaches a value of 5, while L124h can also increase the risk of extravasation [1315]. Created by. Note that the predicted tube length ratio is identical to the channel diameter ratio. Tree-shaped architectures are configurations that correspond to a point-to-volume flow. Curr Probl Diagn Radiol 41(2):5255, Peet RM, Henriksen JD, Anderson TP, Martin GM (1956) Thoracic-outlet syndrome: evaluation of a therapeutic exercise program. Coronal reformatted CECT images depicts extravasated contrast in the upper extremity soft tissues. Other severe Alalaimi M, Lorente S, Wechsatol W, Bejan A. o [ abdominal pain pediatric ] Figure4 depicts cross sections of them, and gives an overview of one single lobule, the elemental system. This is indicative of poor stroke volume from tamponade.
