1. 16. Legg-Calvé-Perthes´ disease. Synovitis, cartilage, remodeling

   Författare :Göran Eckerwall; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stromelysin; Sonography; Remodeling; Proteoglycan; Pressure; Osteotomy; MRI; MR imaging; Metaphysis; Legg-Calvé-Perthes; Histology; Hip; Arthrography; Child; Synovitis; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : This thesis evaluates and correlates the findings in a series of children with Legg-Calvé-Perthes´ Disease at the Departments of Orthopedics, University Hospitals in Lund, Sweden and Odense, Denmark during 1984-1993. It focuses on the importance of synovitis and its effect on the cartilage, on the shape of the femoral head in the early phases of LCPD and on femoral head remodeling after proximal femoral varus derotation osteotomy.

3. 17. Post Cardiac Arrest Care : Evaluation of prognostic tools, Patient outcomes and Relatives’ experiences at 6 months after the event

   Författare :Ewa Wallin; Sten Rubertsson; Marja-Leena Kristofferzon; Silvana Naredi; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac arrest; hypothermia; neurological outcome; cerebral oxygenation; MRI; relatives; Medicinsk vetenskap; Medical Science;

   Sammanfattning : The overall aim of the present thesis was to study post-resuscitation care of cardiac arrest (CA) patients treated with target temperature management 33°C with a focus on evaluation of two prognostic tools: variations in cerebral venous saturation and acute magnetic resonance imaging (MRI) findings on the brain post-CA. An additional aim was to investigate patients’ neurological outcome and relatives’ experiences 6 months after the event. LÄS MER

4. 18. On electroconvulsive therapy in depression : Clinical, cognitive and neurobiological aspects

   Författare :Pia Nordanskog; Maria Engström; Aki Johanson; Elna-Marie Larsson; Örjan Smedby; Tom Bolwig; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ECT; electroconvulsive therapy; depression; MRI; cognitive; hippocampus;

   Sammanfattning : Electroconvulsive therapy (ECT) is used worldwide to treat severe mental disorders. The most common mental disorder, and the third leading cause of disease burden in the world is depression. The clinical efficacy of ECT for severe depression is well-established. LÄS MER

5. 19. Deriving biomarkers from computed tomography using deep learning

   Författare :Meera Srikrishna; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; MRI; convoluted neural networks; deep learning; Dementia; Alzheimer s disease; Normal pressure hydrocephalus; brain segmentation;

   Sammanfattning : X-ray computed tomography (CT) and magnetic resonance imaging (MRI) are widely used structural neuroimaging modalities. For brain atrophy assessment and volumetric quantification using automated methods, MRI is the preferred modality due to its superior soft tissue contrast. LÄS MER

7. 20. Computed tomography, magnetic resonance imaging and positron emission tomography in non-Hodgkin's lymphoma

   Författare :Miriam Rodriguez; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; NHL; CT; MRI; PET; malignancy grade; prognosis; residual mass; Onkologi; Oncology; Onkologi; diagnostisk radiologi; Diagnostic Radiology;

   Sammanfattning : Certain aspects of the use of computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) were evaluated in patients with non-Hodgkin'slymphoma (NHL) with the aim of improving the management of these patients.Subjective evaluation of the tumor pattern on CT images, and quantification of tracer uptake using 11C methionine (11C Met) and [18F] fluorodeoxyglucose (18FDG) PET in patients with NHL, were performed to determine their relations to malignancy grade.
