2. 1. On Renal Artery Stenosis

   Author : Hampus Eklöf; Rickard Nyman; David Bergqvist; Bertil Andrén; Lars Lönn; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Renal artery obstruction; Comparative studies; Contrast media; adverse events; Revascularization; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Abstract : Renal artery stenosis (RAS) is a potentially curable cause of hypertension and azotemia. Besides intra-arterial renal angiography there are several non-invasive techniques utilized to diagnose patients with suspicion of renal artery stenosis. READ MORE

4. 2. Boundary Detection in Cardiovascular Ultrasonic Images Based on Multiscale Dynamic Programming

   Author : Quan Liang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale dynamic programming; artery measurement; cardiac measurement; edge-preserving smoothing; ultrasonic imaging; boundary detection;

   Abstract : Non-invasive ultrasonic imaging is widely used in cardiovascular studies as well as clinical diagnostics. This is due to its non-invasiveness, low cost and easy operation. However, ultrasonic images are noisy and present artifacts, speckles, and echo dropouts. READ MORE

5. 3. Ultrasound as predictor of perinatal outcome

   Author : Gisela Ghosh; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Doppler; Ultrasound; fetus; amniotic fluid index; nuchal cord; uterine artery; umbilical vein; fetal growth restriction; umbilical artery; pulsation; pregnancy;

   Abstract : The aim of the work described in this thesis was to evaluate the value of ultrasound examinations of the amniotic fluid, umbilical cord and blood flow velocity waveform of the fetal and placental vessels as predictors of the perinatal outcome. In the first study, the amniotic fluid index (AFI) measured on admission to the labour ward was evaluated in low-risk pregnancies. READ MORE

6. 4. Coronary artery bypass surgery without extracorporeal circulation

   Author : Jenny Vedin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Cardiopulmonary bypass; off pump; hemodynamics; myocardial damage; inflammation; hemostasis; cognitive function;

   Abstract : Introduction: Coronary artery bypass surgery with extracorporeal circulation is associated with a systemic inflammatory response syndrome that contributes to morbidity and mortality. Aortic cross clamping and cardioplegic arrest induces an ischemic insult to the heart and is a risk factor for neurological injury. READ MORE

7. 5. Magnetic Resonance Imaging of the Heart : Image quality, measurement accuracy and patient experience

   Author : Britt-Marie Ahlander; Jan Engvall; Elisabeth Ericsson; Eva Maret; Marcus Carlsson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Medicin;

   Abstract : Background: Non-invasive diagnostic imaging of atherosclerotic coronary artery disease (CAD) is frequently carried out with cardiovascular magnetic resonance imaging (CMR) or myocardial perfusion single photon emission computed tomography (MPS). CMR is the gold standard for the evaluation of scar after myocardial infarction and MPS the clinical gold standard for ischemia. READ MORE
