  1. 1. Quantification of pulmonary scintigraphy

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Erik Lundin; Urban Karlbom; Wilhelm Graf; Anders Dolk; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; colectomy; constipation; radio-opaque markers; rectal compliance; rectal sensation; scintigraphy; segmental colonic resection; segmental colonic transit; sphincter pressure; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : 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... LÄS MER

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

    Författare :Ulf Öhrvall; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Adrenocortical carcinoma; endocrine pancreatic tumors; mid-gut carcinoids; intraoperative gammadetection; octreotide; scintigraphy; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : 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. LÄS MER

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

    Författare :Björn Pilebro; Ole Suhr; Henning Mölgaard; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloidosis; Transthyretin; Cardiomyopathy; Echocardiography; Scintigraphy; Positron emission tomography; cardiovascular disease; hjärt- och kärlforskning; kardiologi; Cardiology; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : 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.

  7. 5. Bone turnover markers and prediction of bone loss in elderly women

    Författare :Janaka Lenora; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone turnover markers; DXA; elderly; osteoporosis; scintigraphy; Bone mineral density; quantitative ultrasound of the calcaneus; bone loss;

    Sammanfattning : Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. LÄS MER
