2. 1. Radiography and bone scintigraphy in osteoarthritis of the knee: comparison with MR imaging

   Author : Torsten Boegård; Lund Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; MR imaging; bone scintigraphy; osteophyte; joint space width; weight-bearing; radiograms; Knee joint; osteoarthritis; tomografi; medicinsk instrumentering;

   Abstract : The aim was to compare radiography of the tibiofemoral joint (TFJ) and the patellofemoral joint (PFJ), as well as bone scinigraphy with MR imaging in middle-aged individuals with chronic knee pain in the format of a prospective study of knee osteoarthritis. Individuals aged 35-54 years with chronic knee pain were identified. READ MORE

4. 2. MRI with MR Angiography in Endovascular Repair of Abdominal Aortic Aneurysms

   Author : Lena Engellau; Malmö Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; radiology; Clinical physics; Contrast media complications; Cost analysis; MR velocity mapping; Artefacts; MR imaging safety; MR angiography; MR imaging; Endovascular repair; Stent-graft; aortic; Aneurysm;

   Abstract : The aim of this study was to evaluate MRI with contrast enhanced MR angiography (MRI/CE MRA) as imaging method before and after endovascular repair of abdominal aortic aneurysms (AAA). A 1.5 T scanner was used for all examinations. In this prospective study 26 consecutive patients were included. READ MORE

5. 3. PET and MR imaging in prostate cancer

   Author : Kristina Sandgren; Tufve Nyholm; Joakim Jonsson; Camilla Thellenberg-Karlsson; Lennart Blomqvist; Heidi Lyng; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; PSMA; MRI; PET MRI; imaging; prostate cancer; intraprostatic tumour detection; radiofysik; radiation physics;

   Abstract : The current risk assessment of prostate cancer (PC) relies on histopathological samples from biopsies and clinical variables such as prostate-specific antigen (PSA). However, this comes with uncertainties and in some cases it can be challenging to separate patients who would benefit from radical treatment and those who would not. READ MORE

6. 4. Optimisation in strategies in diffusion tensor MR imaging

   Author : Stefan Skare; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Diffusion tensor; magnetic resonance imaging; optimisation; artefacts;

   Abstract : With diffusion MR imaging, the Brownian motion (or self-diffusion) of water molecules is measured. In the corresponding ADC (Apparent Diffusion Coefficient) image, each image element (voxel) represents the average diffusion. In MRI, the diffusion is measured with diffusion gradients along certain directions in space. READ MORE

7. 5. Anterior shoulder dislocation : Aspects of alternative methods of treatment and MR imaging

   Author : Göran Wintzell; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Shoulder; traumatic primary dislocation; arthroscopic lavage; non-operative regime; Indirect MR arthrography; apprehension position; ABER position; Bankart operation; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

   Abstract : Sixty patients (16-30 years) with traumatic primary anterior shoulder dislocation were allocated to arthroscopic lavage or non-operative treatment. The arthroscopic lavage group had a lower recurrence rate, better functional outcome and anterior stability after one year. READ MORE
