1. 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
2. Error reduction strategies for quantitative PET with focus on hybrid PET/MRI
Sammanfattning : Positron Emission Tomography (PET) is an important tool for detection, staging and follow-up in a wide range of diseases, including cancer and neurological disorders. As a functional imaging tool, PET can visualize biological processes, where positron emitting radioactive isotopes are connected to molecules with different functions in the body. LÄS MER
3. PET and MR imaging in prostate cancer
Sammanfattning : 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. LÄS MER
4. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections
Sammanfattning : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. LÄS MER
5. PET and MRI of Prostate Cancer
Sammanfattning : Prostate cancer (PCa) is the most common non-skin malignancy of men in developed countries. In spite of treatment with curative intent up to 30-40% of patients have disease recurrence after treatment, resulting from any combination of lymphatic, hematogenous, or contiguous local spread.
