(a) Axial noncontrast-enhanced CT scan demonstrating a hyperdense oval representing the injectable hydrogel marker with some diffusion at the level of the cervix (red arrows). The tandem is located anterior to the fiducial marker. (b) Axial T1-weighted MRI without contrast demonstrating the hydrogel marker with surrounding edema (red arrows) and a lack of clearly identifiable fiducial marker at the level of the cervix. CT = computed tomography; MRI = magnetic resonance imaging. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
