1. MRI-Only Radiotherapy of Prostate Cancer. Development and Evaluation of Methods to Assess Fiducial Marker Detection, Geometric Accuracy and Dosimetric Integrity
Sammanfattning : .... LÄS MER
2. Geometric distortions in MRI based radiotherapy and PET/MRI
Sammanfattning : Magnetic resonance imaging (MRI) offers high soft-tissue contrast compared to computed tomography (CT). This contrast is helpful in many cases, not least for delineating tumours for radiotherapy treatment, and has led to increasing use in radiotherapy treatment planning (RTP). LÄS MER
3. Validation and clinical implementation of an MRI-only prostate cancer radiotherapy workflow
Sammanfattning : The radiotherapy workflow for prostate cancer is associated with systematic uncertainty stemming from the registration between the computed tomography (CT) and magnetic resonance (MR) images. A radiotherapy workflow based solely on MR imaging (MRI), called an MRI-only workflow, has been suggested as a means of eliminating this uncer¬tainty. LÄS MER
4. Diffusion tensor magnetic resonance imaging of the brain : Tractography analysis with application in healthy individuals and patients
Sammanfattning : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. LÄS MER
5. Evaluation of MRI as a diagnostic method in biliary tract conditions
Sammanfattning : The diagnostic value of modern fast pulse sequences and breath-hold technique was evaluated in a prospective study of patients with suspected biliary diseases. The cost-effectiveness of MRI compared to ultrasound was calculated. LÄS MER
