Effects of nonlinear noise reduction algorithms on image quality in computed tomography systems. Evaluations using human observers and methods for assessing distortion
(2022-11-10)Many conventional radiological examinations have during the past decades been replaced by examinations performed on computed tomography (CT) systems. One reason is that a CT system, in contrast to a conventional X-ray ... -
Effects on quality of life of new radiotherapy techniques in treatment of head and neck cancer
(2022-08-26)The treatment of head and neck cancer (HNC) with radiotherapy has greatly evolved during the last twenty-five years with the introduction of new algorithms and techniques such as three-dimensional conformal radiotherapy ... -
Electrosurgical plasma-mediated ablation for application in dermal wound and cartilage debridement - Biochemical, microbiological and clinical effects
(2015-05-22)The state of matter known as plasma has in the latest decades been investigated within different areas of medical treatment. The work presented in this thesis has focused on a specific type of plasma-based electrosurgical ... -
Endometrial Cancer - Studies on recurrences, complications and preoperative diagnostics
(2023-02-27)Introduction: The most common gynecological cancer is Endometrial Cancer (EC). The prognosis is generally favorable, mainly due to an early diagnosis. However, there are subgroups of EC with a higher risk for metastases ... -
Endovascular repair of aortic disease. Clinical and radiological outcomes
(2024-04-11)Background: Endovascular repair of aortic disease has improved but long-term outcome is questioned. Aims: To evaluate radiological and clinical outcome of endovascular aortic repair. Specifically: I. To evaluate if expansion ... -
Endovascular treatment of acute ischemic stroke
(2017-09-01)Background: Intravenous thrombolysis is effective in patients with minor stroke but not in patients with moderate or major stroke due to large vessel occlusion. Endovascular stroke treatment offers a high recanalization ... -
Energy-metabolic aspects of ischemia and pre-treatment: studies in porcine myocardium
(2011-08-23)The focus of this thesis is to clarify mechanisms involved in protective pre-treatment of ischemia by carbon monoxide (CO) and ischemic preconditioning (IP), so that new pro-tective therapies can be designed. This is studied ... -
Engineering tissue – Bacterial cellulose as a potential biomaterial
(2010-05-28)Cardiovascular diseases are still the predominant cause of death among the adult population in the Western world. Diseases such as myocardial infarction and stroke are caused by occluded blood vessels, as a result of ... -
Epidemiological Studies of Childhood Wheeze - Risk factors and Long-term Outcome
(2011-11-18)Wheezing with viral infections is common in childhood and both genetic and environmental factors have been reported to influence the risk of subsequent asthma development. The overall aim of this thesis was to study the ... -
Epidemiology of cutaneous malignant melanoma in Western Sweden
(2016-11-23)The incidence of cutaneous malignant melanoma (melanoma) has been rising worldwide for the past decades, causing a major public health problem. The overall aim for this thesis was to study the epidemiology of melanoma ... -
Epidemiology, diagnostics and treatment of non-melanoma skin cancers
(2018-02-23)Skin cancer, including malignant melanoma and non-melanoma skin cancer (NMSC), is a growing problem due to the increasing incidence in Sweden and in other Caucasian populations. NMSCs are diagnosed as often as all other ... -
Epigenetic influence on cardiovascular protective mechanisms in vivo: explorations of t-PA release and extracellular vesicle genetic content
(2015-05-18)ABSTRACT Background: Ischemic heart disease is one of the leading causes of death globally. This thesis explores endogenous mechanisms protecting against myocardial ischemia in context of epigenetics (changes in gene ... -
EPILEPSY AND CHILDHOOD AUTISM - with special reference to neuropsychiatric aspects on surgical interventions for medically intractable epilepsy
(2009-01-12)Epilepsy is much more common in individuals with autism than in the general population. The extent to which epilepsy influences the outcome of autism is poorly understood. Many children with medically intractable epilepsy ... -

(2008-04-21)The purpose of this thesis was to study and evaluate some aspects of Erectile Dysfunction (ED) in clinical practice, with special focus on the correlation to myocardial infarction, LUTS (lower urinary tract symptoms), ED ... -
Esophagitis: Aspects on bacteriology, pathophysiology and symptomatology
(2018-05-18)Gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) are the two most common diseases causing inflammation of the esophagus, namely, esophagitis. GERD and EoE are different in many aspects, but ... -
Estimation of clinical dose distributions for breast and lung cancer radiotherapy treatments
(2016-11-07)The overall aim of this thesis was to investigate the uncertainties in the dose distribution determined at the treatment planning stage. The work has been based on the main hypothesis that the way of determining dose at ... -
Evaluation of a structured physiotherapy treatment model for patients with lumbar disc herniation
(2013-04-03)Symptoms from lumbar disc herniation are common in the general population. Many discs heal spontaneously and the patient’s symptoms cease. When people have severe pain and sciatica, the recommendation is to start with ... -
