Abstract
In this report, we showcase diffusible iodine-based contrast-enhanced computed tomography (DICE-CT) as a method for improving soft tissue visualization and reducing beam hardening artifact within a stented vessel. This technique is commonly used in our pathology lab to image soft tissue specimens with dense metal implants and to ensure reliable morphological analysis through clear delineation of tissue structures. For this report, a porcine right coronary artery with an implanted metal stent was scanned using both conventional and DICE-CT methods. Upon reconstruction, DICE-CT produced less beam hardening artifact in comparison to traditional micro-CT; furthermore, DICE-CT produced results with morphometric similarity to histology. Accordingly, these differences illustrated the clear advantage of using DICE-CT over conventional micro-CT when imaging soft tissue specimens with dense metal implants.
