  1. 11. Laser Doppler Flowmetry and Imaging: Methodological Studies

    Author : Siv Bornmyr; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital photography.; cold intolerance; sympathetic nervous system; flow cessation external pressure; skin temperature; thermography; skin blood flow; laser doppler imaging; Laser doppler flowmetry; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Laser Doppler flowmetry (LDF) and laser Doppler imaging (LDI) are modern methods for non-invasive and continuous assessment of skin blood flow. The techniques are based on the phenomenon that monochromatic light transilluminating a perfused tissue is spectrally broadened owing to scattering by moving blood cells. READ MORE

  2. 12. CT with 3D-Image Reconstructions in Preoperative Planning

    Author : Angeliki Dimopoulou; Anders Magnusson; Anders Persson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT Angiography; 3D-image reconstructions; haemodialysis; AVF AVG; DIEP flap; surgery time; complicated renal calculi; PNL; true nonenhanced images; virtual nonenhanced images; CT Urography; Radiology; Radiologi;

    Abstract : Computed tomography is one of the most evolving fields of modern radiology. The current CT applications permit among other things angiography, 3D image reconstructions, material decomposition and tissue characterization. CT is an important tool in the assessment of specific patient populations prior to an invasive or surgical procedure. READ MORE

  3. 13. Positron Emission Tomography and Magnetic Resonance Techniques in Diabetes

    Author : Lina Carlbom; Håkan Ahlström; Olle Korsgren; Olof Eriksson; Lars Johansson; Tove Grönroos; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; Magnetic resonance imaging; Magnetic resonance spectroscopy; Type 1 diabetes; Type 2 diabetes; PET MR; Pancreas transplantation; Perfusion; Radiology; Radiologi;

    Abstract : In order to further advance the field of diabetes research there is a great need for establishing validated non-invasive quantitative techniques to study the pancreas and other tissues of importance for blood glucose regulation. The general aim of this thesis was to explore magnetic resonance techniques and positron emission tomography as such tools. READ MORE

  4. 14. Core Biopsy of Breast and Axillary Lesions : Technical and Clinical Aspects

    Author : Shahin Abdsaleh; PG Lindgren; Per Skaane; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Automatic core needle biopsy; Semiautomatic core needle biopsy; Surgical specimen; Dynamic needle behavior; Hormone Receptors; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Abstract : The aims of this work were to image and analyze the needle behavior at automated core biopsy, to investigate the clinical utility of an alternative core biopsy technique using a semiautomated gun in breast and axillary lesions, and also to compare core biopsy with surgical specimens in malignant breast lesions regarding histologic features and hormone receptor expression.In two experimental studies, using butter and silicon phantoms, respectively, the needle pass was imaged and its dynamic behavior studied.

  5. 15. Double-contrast MRI for the staging of rectal carcinoma: Technical aspects and clinical experience

    Author : Nils-Olof Wallengren; Lund Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; Double contrast; MR imaging; Preoperative staging; Rectal carcinoma; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Aim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. READ MORE
