11. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging
Sammanfattning : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. LÄS MER
12. Magnetic Resonance Imaging in Parkinsons's disease and related disoders
Sammanfattning : Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. LÄS MER
13. Multiparametric MRI for evaluation of tumour treatment response : Studies of 177Lu-octreotate therapy of neuroendocrine tumour
Sammanfattning : Clinical assessment of tumour response to treatment largely relies on estimates of tumour size by, e.g., measuring the largest tumour diameters on magnetic resonance (MR) or computed tomography (CT) images, weeks or months after treatment. LÄS MER
14. Pushing diffusion MRI towards new dimensions
Sammanfattning : Diffusion-MRI techniques allow the non-invasive investigation of microstructural changes in living tissues. However, a detailed interpretation of the data is complicated by the fact that multiple microscopic environments with varying diffusion properties all contribute to the measured signal. LÄS MER
15. Nerve diffusion tensor imaging
Sammanfattning : Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that in vivo visualises random translational movement of water molecules. DTI has inherent difficulties with low signal-to-noise ratio, sensitivity to patient motion, field inhomogeneities and fast T2 relaxation. LÄS MER
