    • Training in organizations aims to improve the effectiveness of the people who work for them and, as a result, improve the organisations' efficiency, productivity and competitiveness. Within the framework of the project 'Balanced Information Technology', by the National Institute for Working Life, Ostersund, the project hopes to strengthen the competitive capability of enterprises. The goal of this paper is to contribute some aspects of competence and learning factors concerning work design and change theories in relation to ergonomics.

  • Preoperative staging of rectal carcinoma using double-contrast MR imaging. Technical aspects and early clinical experiences
  • 1996
  • In: Acta Radiologica. - 1600-0455. ; 37:5, s. 791-798
  • Journal article (peer-reviewed)abstract
    • PURPOSE: To improve preoperative staging of rectal carcinoma with MR imaging, using a double-contrast technique. MATERIAL AND METHODS: Imaging was performed in 12 patients before and after i.v. injection of Gd-DTPA and rectal administration of a superparamagnetic contrast medium, mainly containing magnetite. The diagnostic information was evaluated and compared with findings at surgery and histopathological analysis. RESULTS: The superparamagnetic contrast medium enema caused a distension of the rectum and intraluminal signal void, whereas Gd-DTPA enhanced the mucosa in T1-weighted images. This allowed an evaluation of the normal rectal wall and separation of the mucosa, tunica muscularis and perirectal space in all cases, which was not possible in T1- or T2-weighted precontrast images. The rectal carcinoma could be delineated and tumor invasion to the rectal wall determined in all cases. The findings in postcontrast MR corresponded with the findings at histopathological examination in 11 of 12 patients. The histopathological examination in one patient revealed metastases (< 1 cm) in regional lymph nodes, too small to be identified in pre- or postcontrast MR images. CONCLUSION: Double-contrast-enhanced MR imaging allows evaluation of the normal rectal wall and preoperative staging of rectal carcinoma.
