Download or read book Hemodynamic Investigation of the Liver Using Magnetic Resonance Imaging and Computational Fluid Dynamics written by Stephanie Marie George and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cirrhosis is a leading cause of death in the United States and has severe and costly complications. Because of the clinical significance of cirrhosis, it is important that noninvasive methods be developed to detect cirrhosis early and to monitor its progression with advancing liver disease. Previous studies on portal venous hemodynamics have been performed mainly with ultrasound with mixed results. Magnetic Resonance Imaging offers several advantages over ultrasound including acquisition of both high quality anatomical and hemodynamic information. Phase-Contrast MR was used to gather velocity data for the portal venous system. Methods were developed to perform registration, segmentation and isolation of the portal vein geometries and velocity data. Computational Fluid Dynamics was also employed to further investigate the flow within the portal vein. Velocity data for the portal vein, superior mesenteric vein, splenic vein and the right or left portal vein was acquired in varying numbers for both data sets. Even with the limited number of subjects a few parameters were significant. Patients with cirrhosis had a significantly increased portal vein area and a significantly decreased average velocity per liver volume and velocity variance. Patients with cirrhosis had a significantly increased splenic vein area and average flow rate per liver volume. While these results are preliminary due to small sample size, they are promising and require further investigation and more subjects including varying stages of disease.

Download or read book Ultrasound Elastography written by Monica Lupsor-Platon and published by BoD – Books on Demand. This book was released on 2020-03-04 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastography, the science of creating noninvasive images of mechanical characteristics of tissues, has been rapidly evolving in recent years. The advantage of this technique resides in the ability to rapidly detect and quantify the changes in the stiffness of soft tissues resulting from specific pathological or physiological processes. Ultrasound elastography is nowadays applied especially on the liver and breast, but the technique has been increasingly used for other tissues including the thyroid, lymph nodes, spleen, pancreas, gastrointestinal tract, kidney, prostate, and the musculoskeletal and vascular systems. This book presents some of the applications of strain and shear-wave ultrasound elastography in hepatic, pancreatic, breast, and musculoskeletal conditions.

Download or read book Cystogenesis written by Jong Hoon Park and published by Springer. This book was released on 2016-10-12 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a highly prevalent hereditary renal disorder in which fluid-filled cysts are appeared in both kidneys. Main causative genes of ADPKD are PKD1 and PKD2, encoding for polycystin-1 (PC1) and polycystin-2 (PC2) respectively. Those proteins are localized on primary cilia and function as mechanosensor in response to the fluid flow, translating mechanistic stimuli into calcium signaling. With mutations either of PKD1 or PKD2, hyper-activated renal tubular epithelial cell proliferation is observed, followed by disrupted calcium homeostasis and aberrant intracellular cyclic AMP (cAMP) accumulation. Increased cell proliferation with fluid secretion leads to the development of thousands of epithelial-lined, fluid-filled cysts in kidneys. It is also accompanied by interstitial inflammation, fibrosis, and finally reaching end-stage renal disease (ESRD). In human ADPKD, the age at which renal failure typically occurs is later in life, however no specific targeted medications are available to cure ADPKD. Recently, potential therapeutic targets or surrogate diagnostic biomarkers for ADPKD are proposed with the advances in the understanding of ADPKD pathogenesis, and some of them were attempted for clinical trials. Herein, we will summarize genetic and epi-genetic molecular mechanisms in ADPKD progression, and overview the currently available biomarkers or potential therapeutic reagents suggested.

Download or read book Cardiovascular Computed Tomography written by James Stirrup and published by Oxford University Press, USA. This book was released on 2020-01-02 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen a marked increase in cardiovascular computed tomography (CT) imaging, with the technique now integrated into many imaging guidelines, such as those published by ESC and NICE. Rapid clinical and technological progress has created a need for guidance on the practical aspects of CT image acquisition, analysis and interpretation. The Oxford Specialist Handbook of Cardiovascular CT, now revised for the second edition by practising international experts with many years of hands-on experience, is designed to fulfil this need. The Handbook is a practical guide on performing, analysing and interpreting cardiovascular CT scans, covering all aspects from patient safety to optimal image acquisition to differential diagnoses of tricky images. It takes an international approach to both accreditation and certification, highlighting British, European, and American examinations and courses. The format is designed to be accessible and is laid out in easy to navigate sections. It is meant as a quick-reference guide, to live near the CT scanner, workstation, or on the office shelf. The Handbook is aimed at all cardiovascular CT users (Cardiologists, Radiologists and Radiographers), particularly those new to cardiovascular CT, although even the advanced user should find useful tips and tricks within.
Download or read book Liver Cirrhosis and Its Development written by J.L. Boyer and published by Springer Science & Business Media. This book was released on 2001-03-31 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liver cirrhosis is a major clinical problem worldwide and is associated with significant morbidity and mortality from its complications, such as liver cell insufficiency with coagulopathy and hepatic encephalopathy, portal hypertension with ascites and gastrointestinal bleeding, hepatorenal syndrome, HCC development and others. This volume, the proceedings of Falk Symposium 115 held in Basel, Switzerland, October 22-24, 1999 (Part II of the Basel Liver Week 1999; XI International Congress of Liver Diseases) covers our present knowledge of the aetiologies and early stages of liver cirrhosis development. Based on this information, strategies are discussed that are aimed at the prevention, early diagnosis and therapy of chronic liver diseases, thus preventing their progression to cirrhosis and its complications, including HCC development. The main topics mentioned above are complemented by three state-of-the-art chapters on modern aspects of medicine in general and hepatology in particular as well as their perspectives beyond the year 2000: `Molecular Medicine', `New Hepatitis Viruses' and `Genetic Liver Diseases: Diagnosis and Therapy'. Introductory chapters focusing on the more basic aspects of the biology of live cells as well as on the mechanisms underlying fibrogenesis, cholestasis and inflammation will be followed by a detailed discussion of the clinically most important causes of liver cirrhosis worldwide: hepatitis viruses B, C and D; toxins (alcohol, drugs and others) as well as metabolic liver diseases (haemochromatosis, Wilson disease, alpha-1-antitrypsin deficiency, porphyria cutanea tarda and protoporphyria). This book, therefore, will interest clinically oriented basic scientists as well as those in clinical practice, givng an update on many aspects of modern hepatology and its perspectives in the next millennium.
