1. 6. Quantification Methods for Clinical Studies in Nuclear Medicine - Applications in AMS, PET/CT and SPECT/CT

   Författare :Marie Sydoff; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear Medicine; AMS; PET CT; SPECT CT; dosimetry; internal dosimetry; quantification; activity quantification; volume delineation; radiation; biokinetics; pharmacokinetics; biodistribution;

   Sammanfattning : An essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not.

3. 7. Geometric distortions in MRI based radiotherapy and PET/MRI

   Författare :Josef Lundman; Tufve Nyholm; Anne Larsson; Jörgen Olofsson; Marco Riboldi; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; MRI; PET MR; PET MRI; medical imaging; radiotherapy; geometrical distortions; MR-only; MRI-only; radiofysik; radiation physics;

   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

4. 8. Translational PET imaging of inflammation

   Författare :Emmi Puuvuori; Olof Eriksson; Tove Grönroos; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET imaging; Nuclear Medicine; Inflammation; Translational Medicine;

   Sammanfattning : Inflammation is our body’s sophisticated defense mechanism against invading pathogens, traumas, and tumors. Repeatable and non-invasive monitoring of inflammation process would open opportunities to improve our knowledge of several diseases and enable assessment of personalized treatments. LÄS MER

5. 9. Computed tomography, magnetic resonance imaging and positron emission tomography in non-Hodgkin's lymphoma

   Författare :Miriam Rodriguez; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; NHL; CT; MRI; PET; malignancy grade; prognosis; residual mass; Onkologi; Oncology; Onkologi; diagnostisk radiologi; Diagnostic Radiology;

   Sammanfattning : Certain aspects of the use of computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) were evaluated in patients with non-Hodgkin'slymphoma (NHL) with the aim of improving the management of these patients.Subjective evaluation of the tumor pattern on CT images, and quantification of tracer uptake using 11C methionine (11C Met) and [18F] fluorodeoxyglucose (18FDG) PET in patients with NHL, were performed to determine their relations to malignancy grade.

7. 10. Detecting prostate cancer metastases - PET/CT and the sentinel node technique

   Författare :Henrik Kjölhede; Malmö Urologisk cancerforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Metastases; PET CT; Choline; Fluoride; Sentinel lymph nodes;

   Sammanfattning : Prostate cancer is one of the most common malignancies. Its treatment is highly dependent on the presence or absence of metastases. The available invasive and non-invasive modalities for detecting metastases are imperfect. LÄS MER
