  1. 1. Quantification of pulmonary scintigraphy

    Author : Jiahua Xu; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Emphysema; Inhomogeneity; Perfusion; scintigraphy; SPECT; 99mTc-Technegas; Ventilation; V Q;

    Abstract : Modern nuclear medicine techniques, such as SPECT (single photon emission computed tomography), enable quantification and localisation of lung function in small lung elements, but appropriate methods are not yet available. The aim of the present project was therefore to develop and evaluate methods for mapping lung function in planar scintigrams and in SPECT. READ MORE

  2. 2. Slow Transit Constipation : Aspects of Diagnosis and Treatment

    Author : Erik Lundin; Urban Karlbom; Wilhelm Graf; Anders Dolk; Uppsala universitet; []

    Abstract : Oral 111-Indium-DTPA colonic scintigraphy was used to assess segmental transit in 23 patients with slow transit constipation (STC) and 13 controls. The transit time did not differ between patients and controls in the right colon, whereas the patients had a consistent delay from the transverse colon and distally (P... READ MORE

  3. 3. Intraoperative scintigraphic detection of abdominal endocrine tumors : Development and evaluation of hand held gamma sensitive probes for¹¹¹In

    Author : Ulf Öhrvall; Uppsala universitet; []

    Abstract : Surgery of endocrine tumors benefit from accurate pre and- intraoperative localization methods,and scintigraphy has become an important contribution in this respect. In the present thesis therequisites for scintigraphic localization of abdominal endocrine tumors and new detectors forintraoperative gammadetection are evaluated. READ MORE

  4. 4. The heart in hereditary transthyretin amyloidosis : clinical studies on the impact of amyloid fibril composition

    Author : Björn Pilebro; Ole Suhr; Henning Mölgaard; Umeå universitet; []

    Abstract : Background Hereditary transthyretin amyloid (ATTRm) amyloidosis is a systemic disease mainly affecting the peripheral nervous system and the heart. The disease is inherited in an autosomal dominant manner with a varying penetrance. It is caused by mutations in the transthyretin (TTR) gene. Today more than 100 disease causing mutations are known.
