1. 11. Non-enhanced single-energy computed tomography of urinary stones

   Författare :Johan Jendeberg; Mats Lidén; Per Thunberg; Anders Magnusson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostic; CT; urinary stone; kidney stone; urolithiasis; phlebolith; uric acid; spontaneous passage; CNN; artificial intelligence;

   Sammanfattning : Computed tomography (CT) is the mainstay imaging method for urinary stones.The aim of this thesis was to optimize the information obtained from the initial CT scan to allow a well-founded diagnosis and prognosis, and to guide the clinician as early and as far as possible in the further treatment of urinary stone disease.

3. 12. Alternative Methods for Assessment of Split Renal Function

   Författare :Henrik Björkman; Anders Magnusson; Jonas Wadström; Torbjörn Andersson; Uppsala universitet; []
   Nyckelord :Radiology; Split renal function; Live kidney donor; CT; Renography; Dynamic MRI; Renal volume; Respiratory triggering; Radiologisk forskning;

   Sammanfattning : Living kidney donation is a clinical situation with unique features in the sense that healthy individuals voluntarily expose themselves to certain risks and inconveniences. Therefore, eliminating as much of the associated discomfort as possible is crucial. LÄS MER

4. 13. 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.

5. 14. Scaphoid Fractures - epidemiology, diagnosis and treatment

   Författare :Peter Jörgsholm; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scaphoid fracture; carpal fracture; paediatric; radiography; CT; MRI; arthroscopy; scapholunate ligament injury; radial comminution; surgical treatment; conservative treatment; fracture union;

   Sammanfattning : Abstract The scaphoid is the most commonly fractured carpal bone. The diagnosis is difficult and untreated the long-term results are poor. Approximately 10% do not unite even if they are treated properly. The aim of this thesis was to study scaphoid fracture epidemiology, diagnosis and treatment. LÄS MER

7. 15. Diagnosis and evaluation of therapeutic response of bone metastases

   Författare :Ipek Çiray; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Bone metastases; breast neoplasm; MR imaging; CT; diagnosis; therapy evaluation; Onkologi; Oncology; Onkologi; diagnostisk radiologi; Diagnostic Radiology;

   Sammanfattning : The aim of this study was to investigate different aspects of different imaging modalities in the diagnosis of bone metastases and in the assessment of their response to therapy. The role of CT, with and without clinical information, was investigated as compared to CT-guided bone biopsy in the evaluation of suspected bone metastases. LÄS MER
