ABSTRACT:
Radioactive sources, preferably radioactive seeds, for use in brachytherapy comprising a radioisotope within a sealed biocompatible container, wherein at least one part of the outer surface of the container is grooved, preferably with a curved groove. The grooved outer surface is preferably substantially free from angularities. Such grooves enhance the echogenicity of the source using medical ultrasound at a greater range of angles to the ultrasound probe, thus enhancing the ultrasound visibility of the source. Preferred radioisotopes are palladium-103 and iodine-125.
