1. Correlation between PET/MRI image features andpathological subtypes for localized prostate cancer
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Prostate cancer is the most common cancer in Sweden. Patients with the condition have a good prognosis in general and most cases can be treated. LÄS MER
2. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologiSammanfattning : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. LÄS MER
3. MRAC capable phantom fluids : A study of hybrid phantom fluids for attenuation correction in PET/MRI and PET/CT
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : Background. Classification based PET/MRI attenuation correction methods utilize a PET/CT derived method of identifying tissues and assigning them attenuation values. Phantoms for PET/MRI generally use theoretical attenuation maps.Aim. LÄS MER
4. Differences in tumor volume for treated glioblastoma patients examined with 18F-fluorothymidine PET and contrast-enhanced MRI
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Background: Glioblastoma (GBM) is the most common and malignant primary brain tumor. It is a rapidly progressing tumor that infiltrates the adjacent healthy brain tissue and is difficult to treat. Despite modern treatment including surgical resection followed by radiochemotherapy and adjuvant chemotherapy, the outcome remains poor. LÄS MER
5. Natural sugar as an MRI contrast agent for brain cancer detection using chemical exchange saturation transfer (CEST) imaging at 3T
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Hjärntumörer utgör cirka 2,5% av alla cancerdiagnoser i Sverige (2013) och femårsöverlevnaden är cirka 50%. Hjärntumörer diagnostiseras med bildtagningstekniker såsom datortomografi (CT), positronemissionstomografi (PET) och magnetkamera (MR). LÄS MER
