2. 1. The impact of duplex scanning in the management of chronic lower limb arterial disease

   Author : Annika Boström Ardin; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Duplex; Ultrasound; lower extremity; arterial; chronic ishemia; selection; surgery; PTA; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Abstract : In patients with chronic lower extremity ischemia in which endovascular or surgical intervention is considered non-invasive evaluation by duplex scanning provides important anatomical and hemodynamic information. The aim of this thesis was to evaluate the impact of duplex scanning in the selection of various therapeutic alternatives in limbs with lower extremity arterial insufficiency. READ MORE

4. 2. Aspects on Chronic Venous Disease of the Lower Limb

   Author : Gudmundur Danielsson; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; ortopedi; traumatologi; Cardiovascular system; Kardiovaskulära systemet; traumatology; orthopaedics; Surgery; duplex ultrasound; foot volumetry; Chronic venous disease; CEAP classification;

   Abstract : Controversies exist regarding both what is required for a proper diagnosis of chronic venous disease (CVD), and what treatment to offer patients. An objective evaluation is mandatory to individualize treatment. READ MORE

5. 3. Infrainguinal Percutaneous Transluminal Angioplasty in Limbs with Severe Lower Limb Ischaemia

   Author : Anne-Marie Löfberg; Wojciech Cwikiel; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; infrainguinal; chronic ischaemia; percutaneous transluminal angioplasty; duplex; bypass grafts; Onkologi; Oncology; Onkologi; radiologi; Radiology;

   Abstract : Infrainguinal bypass grafting is an established method in the treatment of patients with femoropopliteal and crural occlusive disease leading to critical lower limb ischaemia (CLI). However, complications related to surgical procedure are not negligible and percutaneous transluminal angioplasty (PTA) has emerged as an alternative. READ MORE

6. 4. Noninvasive assessment of cerebral circulation before, during and after carotid surgery

   Author : Helene Zachrisson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal carotid artery disease; cerebrovascular hemodynamics; Carotid thrombendarterectomy; Duplex ultrasound; transcranial Doppler; Internal carotid artery disease;

   Abstract : Non-invasive ultrasound investigations were evaluated in patients with carotid artery stenosis in comparison with radiological disease gradations and perioperative blood pressure measurements. The aim was to assess cerebrovascular hemodynamics before, during and after carotid thrombendarterectomy (CEA) in relation to the clinical outcome of the surgical intervention. READ MORE

7. 5. Signal Processing for Spectroscopic Applications

   Author : Erik Gudmundson; Peter Stoica; Peter Händel; Stoica Stoica; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral estimation; spectroscopic techniques; MRI; NMR; NQR; signal detection; parameter estimation; missing data; non-uniform sampling; damped sinusoids; detection of explosives; T1-mapping; relaxometry; brain imaging; skin imaging; blood velocity estimation; medical ultrasound; Signal processing; Signalbehandling; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Abstract : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.
