  1. 1. Postpartum Ultrasound

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ajlana Mulic-Lutvica; Uppsala universitet.; [2007]
    Keywords : Medicine; Postpartum ultrasound; Uterine artery Doppler; Retained placental tissue; Secondary postpartum hemorrhage; Puerperium; Endometritis postpartum; Cesarean section; Medicin;

    Abstract : This study was undertaken to investigate the involutional changes of the uterus and uterine cavity by ultrasound (US), gray-scale and Doppler, after normal delivery, and to compare with the corresponding findings from women with puerperal complications, particularly retained placental tissue (RPT). The overall design was exploratory and prospective, with the use of descriptive statistics for analysis. READ MORE

    Abstract : We studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. READ MORE

  4. 4. On perfusion estimation using ultrasound

    University dissertation from Department of Electrical Measurements, Lund University

    Author : Tomas Jansson; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; Speckle; Artifacts; Perfusion; Ultrasound; Doppler; Mät- och instrumenteringsteknik;

    Abstract : This thesis has the main focus on ways to improve the blood perfusion estimate, as obtained from a continuous wave Doppler system. Earlier studies have shown large temporal variations in the detected perfusion estimate, due to speckle. READ MORE

  5. 5. Ultrasound-enhanced Fibrinolysis Pro-fibrinolytic and Non-beneficial Effects Of Ultrasound Exposure

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Bjarne Madsen-Härdig; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Thrombolysis; Cardiovascular system; Fibrinolysis; Ultrasound;

    Abstract : The aim of this study was to further clarify the pro-fibrinolytic effects, and to explore the possible non-beneficial effects in ischemic organs, during exposure to pulsed ultrasound. This was accomplished by studies of the effects of different intensities of pulsed ultrasound exposure on the fibrinolytic properties of streptokinase and reteplase. READ MORE
