    Abstract : This thesis addresses infections in prostate biopsy – a global problem. Over 3 million prostate biopsies are performed annually and 3% of men suffer a severe infection. The risk of infection is increasing in parallel with rising antibiotic resistance. READ MORE

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

    Author : Shahin Abdsaleh; PG Lindgren; Per Skaane; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.

  3. 3. Comparison of stereotactic fine needle aspiration biopsy and core needle biopsy in breast lesions

    Author : Karin Leifland; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Purpose: The purpose of this study was to evaluate the diagnostic value of two biopsy methods by comparing stereotactic fine needle aspiration biopsy (S-FNAB) with stereotactic core needle biopsy (S-CNB). The biopsies were performed by the same radiologist, in the same breast lesion on the same occasion, in order to establish which method that best can be recommended in different kind of mammographically detected lesions.

    Abstract : For the diagnosis of prostate cancer, there is a need to develop biopsy strategies, that give representative information both for detection of cancer and for assessment of prognostic indicators.In 80 men, transrectal core biopsies from 10 standardized positions were taken before radical prostatectomy.

  5. 5. Desmoid tumors. New aspects on diagnostic procedures, treatment and outcome

    Author : Mikael Dalén; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : desmoid; fibromatosis; surgery; radiotherapy; chemotherapy; statistics; imaging; studies; cytology; biopsy; pathology;

    Abstract : Desmoid tumor (aggressive fibromatosis) is a rare, benign fibroblastic/myofibroblasticneoplasm that originates from musculoaponeurotic structures. It never metastasizes but locallygrows aggressively and infiltrates surrounding tissues. The treatment of choice has beensurgery. However, local recurrences are frequent. READ MORE
