  2. 11. Pituitary Tumors - Epidemiology and the Diagnostic Value of 68Ga-DOTATOC PET

    Author : Axel Tjörnstrand; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; Pituitary neuroendocrine tumor; pituitary tumor; somatostatin receptor imaging; gallium68; 68Ga; SSTR; SSTR-PET;

    Abstract : Pituitary neuroendocrine tumors (PitNETs) are considered common in the general population. However benign in most cases, these tumors can evoke dramatic morbidity in patients with aggressive tumor growth and/or excess hormone secretion. READ MORE

    Abstract : The use of positron emission tomography (PET) for imaging in oncology has grown rapidly in recent years. 2-[18F]-fluorodeoxyglucose (FDG) is the most common tracer of PET, although drawbacks exist. READ MORE

  6. 14. Imaging brain aromatase by using PET : A way to study anabolic steroid abuse

    Author : Kayo Takahashi; Mats Bergström; Bengt Långström; Yasuyoshi Watanabe; Torbjörn Bäckström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aromatase; brain; molecular imaging; PET; [11C]Vorozole; amygdala; hypothalamus; anabolic-androgenic steroids; abuse; [18F]Vorozole analogs; Neuroscience; Neurovetenskap;

    Abstract : Aromatase is an enzyme that facilitates the conversion of androgens to estrogens and may play a role in mood and mental status. The main theme of this thesis is the imaging of brain aromatase by use of the PET technique. The PET tracer for aromatase, 11C-labeled vorozole (VOZ) was developed and evaluated by with in vitro and in vivo methods. READ MORE

  7. 15. PET/CT in oncology : Patient experience, image quality and the value of information

    Author : Camilla Andersson; Birgitta Johansson; Håkan Ahlström; Pernilla Lagergren; Uppsala universitet; []
    Keywords : PET CT; patient experience; image quality.; Medicinsk vetenskap; Medical Science;

    Abstract : The overall aim was to investigate patients’ experiences with a PET/CT examination, satisfaction with care provided in connection to the examination and whether web-based information can improve satisfaction with care and image quality, compared to standard care. An additional aim was to explore how satisfaction with care and image quality is associated with health-related quality of life (HRQoL) and perceived stress. READ MORE
