1. Extrakardiellt upptag på myokardscintigrafibilder : En fantomstudie som undersöker den visuella och kvantitativa påverkan på hjärtat
Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)Sammanfattning : 99mTecknetium-tetrofosmin är ett radiofarmaceutiskt medel som används vid myokardscintigrafi för att bedöma myokardperfusionen genom att avbilda vänsterkammarens blodflöde. Radiofarmakat uppvisar ett lågt myokardiellt upptag på endast 1,2%, där majoriteten av resterande radiofarmaka rensas ut genom levern och utsöndras via gallsystemet. LÄS MER
2. Feasibility of quantitative 99mTc-DPD scintigraphy SPECT/CT for assessing the burden of ATTR cardiac amyloidosis
Master-uppsats, Umeå universitet/RadiofysikSammanfattning : Background: Amyloid transthyretin (ATTR) cardiomyopathy is caused by the deposition of misfolded proteins, known as amyloid fibrils, in the myocardium. Quantitative Single Photon Emission Computed Tomography (QSPECT) utilizing 99mTc-DPD scintigraphy has the potential to assess ATTR-suspected cardiac amyloidosis (CA). LÄS MER
3. Feasibility of single time point dosimetry during 177Lu-PSMA-617 treatments of prostate cancer
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Introduction: Standard dosimetry methods for radionuclide therapies re- quire imaging at multiple time points post injection. An alternative method has been presented in the literature that uses previously acquired pharma- cokinetic data to create so-called dose factors. LÄS MER
4. Feasibility of Dynamic SPECT-Renography with Automated Evaluation Using a Deep Neural Network
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Introduction: Renography is a standard diagnostic examination that evaluates renal function, renal pelvic dilatation and urinary obstruction. Renography is performed by injecting a radiopharmaceutical (predominately 99mTc-MAG3) and using gamma camera to image the biodistribution in a dynamic sequence. LÄS MER
5. Evaluation of internal dosimetry for 225- Ac using one single measurement based on 111-In imaging
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Background and aim: There is a high interest in determining the absorbed dose in tumors and organs for various radiotherapy cancer treatments. Due to limitations in today's methods of determining the patient specific absorbed dose it is usually not proceeded clinically. LÄS MER
