“μCT scanning of low density porous polymer scaffolds leads to insufficient imaging ability due to poor contrast. In order to enhance their X-ray absorption, one might trial several approaches using contrast agents. This methods paper is aimed at guiding scientists in applying the most appropriate contrast enhancement method for CT imaging of such materials, by reporting both the positive and the negative results. Iodine staining coupled with chemical drying was the most efficient approach, allowing for contrast enhancement, morphology preservation, and high resolution all at once.”
