1. 1. Aspects of PET-CT in prostate cancer. Protocol optimization, diagnostic accuracy, and dosimetry

   Författare :Mimmi Bjöersdorff; Malmö Nuklearmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET-CT; Prostatacancer; [18F]FCH; [18F]PSMA-1007; optimering; diagnostisk noggrannhet; dosimetri; PET-CT; Prostate Cancer; [18F]FCH; [18F]PSMA-1007; Optimization; Diagnostic accuracy; Dosimetric;

   Sammanfattning : The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. LÄS MER

3. 2. Artificial Intelligence-based Assessment of Prostate Cancer Metastases in PET/CT

   Författare :Sarah Lindgren Belal; Malmö Nuklearmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artificial intelligence AI ; Convolutional neural networks CNN ; PET CT; Prostate cancer; Automated; Tumor burden; Bone metastases; Lymph node metastases;

   Sammanfattning : Background: Quantification of tumor burden from bone scan in the form of automated Bone Scan Index (aBSI) has been validated as an imaging biomarker for patients with prostate cancer. Positron emission tomography combined with computed tomography (PET/CT) is more sensitive and accurate compared to conventional imaging such as bone scan. LÄS MER

5. 4. Lung function in smokers - Aspects on COPD diagnosis and associations to atherosclerosis and alcohol consumption

   Författare :Sophia Frantz; Malmö Klinisk fysiologi och nuklearmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lung function; smoking; COPD; IOS; atherosclerosis; alcohol consumption;

   Sammanfattning : Smoking is the most common and important risk factor for reduced lung function. Chronic Obstructive Pulmonary Disease (COPD) affects mainly smokers and is characterized by airflow obstruction, assessed using one of two major diagnostic spirometric criteria. LÄS MER

7. 5. Deposition and absorption of inhaled drugs

   Författare :Eva Bondesson; Malmö Klinisk fysiologi och nuklearmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; technetium-99m; radionuclide imaging; radioactive aerosol; powder inhaler; pharmacokinetics; mucociliary clearance; lung deposition; gamma scintigraphy; inhalation; deposition modelling; drug absorption; absorption enhancer; aerosol; medicinsk instrumentering; Physiology; Fysiologi;

   Sammanfattning : Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess the influence of a surface active agent (sodium taurocholate, a bile salt) on the deposition and absorption of an inhaled hydrophilic solute. Repeated planar gamma scintigraphy was found to provide the same information on total pulmonary drug deposition as an independent method that involved assessments of urinary drug recovery after blockage of gastrointestinal drug absorption when all of the critical parts of the methodological procedures were accurately and meticulously executed.
