  1. 1. Radon in Groundwater- Influencing Factors and Prediction Methodology for a Swedish Environment

    Författare :Kirlna Skeppström; Bo Olofsson; Per Erik Jansson; Jon Petter Gustafsson; Gerhard Barmen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon; Grondwater; GIS; RV method; Multivariate statistics; Water engineering; Vattenteknik;

    Sammanfattning : This thesis presents a method for predicting radon (222Rn) levels in groundwater on a general scale, within an area of approximately 185 x 145 km2. The method applies to Swedish conditions, where 222Rn is the main contributor to natural radioactivity. LÄS MER

  3. 2. On the assessment of right ventricular function using cardiac magnetic resonance imaging and echocardiography

    Författare :Stina Jorstig; Per Thunberg; Kent Emilsson; Mats Lidén; Micael Waldenborg; Einar Heiberg; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; right ventricle; stroke volume; ejection fraction; cardiac magnetic resonance; ehocardiography; Kirurgi; Surgery;

    Sammanfattning : Transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) imaging are two commonly used imaging modalities for evaluating the size and function of the heart. There are advantages and disadvantages associated with both modalities when examining the right ventricle (RV). LÄS MER

  4. 3. Treatment of Right Ventricular Failure through Partial Volume Exclusion : An Experimental Study

    Författare :Per Vikholm; Laila Hellgren; Lund Lars; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Right Heart Failure; Left Ventricular Assist Device; Glenn shunt; Thorax Surgery; Thoraxkirurgi;

    Sammanfattning : Implantation of a left ventricular assist device (LVAD) is a potential treatment in terminal heart failure. Right ventricular (RV) failure is a severe complication in these patients and sometimes requires additional placement of a right ventricular assist device (RVAD). LÄS MER

  5. 4. The right ventricle in volume or pressure overload : Insights from novel imaging techniques

    Författare :Aleksandra Trzebiatowska-Krzynska; Eva Swahn; Niels Erik Nielsen; Lars Wallby; Marcus Carlsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This study is inspired by the gap in knowledge regarding the timing of cardiac surgery and interventions in adult patients with congenital heart disease. There are many parameters used assessing right ventricular function; however, most of them have pitfalls. LÄS MER

  7. 5. Right heart function in health and disease : a doppler echocardiography and doppler tissue imaging study

    Författare :Per Lindqvist; Elsadig E Kazzam; Anders Waldenström; Lars Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler tissue imaging; right ventricle; cardiac catheterisation; isovolumic relaxation; isovolumic contraction; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: It is well known that performance of the right ventricle (RV) determines exercise capacity and may confer prognostic information in different cardiopulmonary diseases. To allow optimal patient management, ideal methods to assess right heart function are therefore important. LÄS MER
